Factors associated with hygiene practices among primary school children in southern Ethiopia

BackgroundEight years into the Sustainable Development Goal period, Ethiopia is not on track to achieve good hygiene practices among school children. Ensuring good hygiene practices among primary school children to prevent the spread of communicable diseases remains a challenge in most primary schools in Ethiopia. Therefore, the aim of this study was to identify factors associated with hygiene practices among primary school children in southern Ethiopia.MethodsA school-based cross-sectional study was conducted from June 3 to July 28, 2022, in five primary schools. The simple random sampling technique was used to select the school. Subsequently, 640 students were selected from the proportionally allocated sample size. Pretested semi-structured interviewer-administered questionnaires and observational checklists were utilized to collect data. The data was then entered into EpiData version 4.6 and analyzed using SPSS version 25. Variables with a p ≤ 0.25 at bivariate analysis were used to develop a multivariable logistic model to identify factors associated with hygiene practices. P < 0.05 with a 95% confidence interval was considered statistically significant.ResultsThe magnitude of overall good hygiene practices was 29.2% (95% CI: 25.81–32.59). Urban residence (AOR = 3.4, 95% CI 2.1–5.55), knowledge of handwashing (AOR = 4.5, 95% CI 2.8–7.36), being a member of a hygiene and sanitation club (AOR = 3.7, 95% CI 2.4–6.86), and experience of visiting a model school (AOR = 3.1, 95% CI 2.1–5.55) were found to be significantly associated with hygiene practices.ConclusionThe overall level of good hygiene practices in Kedida district was low. Therefore, it is essential to enhance health education on handwashing, establish sanitation and hygiene clubs, and conduct visits to district model elementary schools.

Identification and antimicrobial susceptibility profiles of Campylobacter isolated from camel at municipal abattoirs in eastern Ethiopia

Campylobacteriosis is an infectious zoonotic disease caused by the genus Campylobacter. The disease is transmitted from animals to humans predominantly through the consumption of contaminated food and water. However, the lack of information on the status of Campylobacter makes it difficult to quantify the role of camel meat in the dissemination of the pathogen. A cross-sectional study was conducted from June 2022 to August 2023 to investigate the occurrence of Campylobacter and associated risk factors and to determine the antimicrobial susceptibility profiles of Campylobacter species from camels slaughtered at municipal abattoirs in the towns of Harar, Babile, Jigjiga and Dire Dawa in eastern Ethiopia. A total of 324 (146 carcass swabs, 146 camel feces and 32 abattoir environmental swab samples) were collected and analyzed using TaqMan real-time PCR and culture techniques following standard procedures. In addition, antimicrobial susceptibility tests were performed using the disk diffusion method for eight antimicrobial agents according to the Clinical Laboratory Standards Institute. The overall prevalence of Campylobacter was 7.7%. Campylobacter was more frequently detected from carcasses and surface contact environmental swabs. We isolated Campylobacter at the genus level from approximately half of the PCR-positive samples, representing 54.2% (13 out of 24) of the total. The isolation levels of C. jejuni and C. coli were also 5.56% and 2.2%, respectively, which varied significantly (p = 0.037) based on sample type and site. The odds of occurrence of C. jejuni in samples collected from abattoir environments was 7.52 times greater than those in carcass and fecal samples. We detected resistance to chloramphenicol (78.6%), followed by amoxicillin (71.4%). However, 93%, 78.6%, and 71.4% of the isolates were susceptible to ceftriaxone, ciprofloxacin, and nalidixic acid, respectively. Multidrug resistance (MDR) was detected in 60% of the isolates. Of these MDR isolates, 9 (75%) were C. jejuni and 3 (25%) were C. coli. This study revealed that a considerable proportion of multidrug-resistant Campylobacter species circulate in both camel meat and abattoir environments. This indicates possible carcass cross-contamination by Campylobacter during slaughtering that can pose a threat to humans and limit therapeutic options, which could be prevented by applying good hygienic practices at abattoirs. Therefore, abattoir workers need to be aware of abattoir hygienic standard operating procedures. Regular coordinated actions should be implemented for the rational use of veterinary and medical drugs at the national level, together with training and awareness of hygienic practices.

Quantitative Risk Assessment of Aflatoxin M1 Related to the Consumption of Raw Cow's Milk in Daloa (Côte d’Ivoire)

Cow's milk represents a potential health risk for consumers. The objective of this work is to assess the sanitary quality of raw cow's milk produced and consumed by the populations of Daloa. For this purpose, a total of 30 raw milk samples were collected from 3 raw cow's milk extraction points in the city of Daloa. Mycotoxins were determined using gas chromatography. The results showed that 100% of the analyzed samples were contaminated with aflatoxin M1 (AFLM1). These results indicated that the aflatoxin M1 levels in the analyzed samples exceeded the maximum limit (ML) set by European regulations. To assess the risk of contamination for the population of Daloa, a survey was conducted among consumers of raw cow's milk. A total of 388 individuals were interviewed to gather their opinions. The survey involved a form with questionnaires related to the objectives of the study. This form provided information on identity, marital status, consumption patterns, frequency, quantity, and the socio-economic characteristics of the consumers. The results showed that the risk of liver cancer related to the consumption of raw cow's milk in the city of Daloa is approximately 36.08% to 36.16%; representing 36,080 to 36,150 cases per 100,000 inhabitants. Thus, to ensure consumer safety, good hygiene practices in the preservation of feed for cattle and the construction of enclosures for them must be implemented.

Prevalence, Cross Contamination, Virulence, and Multidrug Resistance Profiles of Staphylococcus aureus Isolates from Four Middle-Scale Dairy Farms in Bareilly, Northern India.

Milk, a nutritious global important food commodity, serves as an excellent medium for microbial growth as well. The foodborne pathogen Staphylococcus aureus is a commensal member of human microflora that enters the food chain through poor hygienic practices and cross contamination and causes various clinical manifestations in humans. During this study, raw milk and swab samples (milker's hand, udder, towel, milking bucket, and farm floor) were collected from four middle-scale buffalo dairy farms. The results revealed S. aureus presence in 11.6% (n = 56/448) bucket raw milk samples and 2.6% (n = 12/448) udder raw milk samples. Contrarily, S. aureus prevalence was significantly higher in farm floors (100%, n = 84/84), towel (35.7%, n = 10/28), milking bucket (11.6%, n = 56/448), milker's hand (10.7%, n = 3/28), and udder swab samples (4.0%, n = 18/448). The chi-square test yielded p values of 0.000, 0.005, and 0.0011 for udder raw milk, udder swab, and milker's hand swab, respectively. The p values of the milking bucket (p = 0.048) and farm floors (p = 0.0183) confirmed their possible role in S. aureus cross contamination. Gene amplifications of nuclease and enterotoxin A indicate potential virulence of S. aureus isolates in collected samples. Antibiotic susceptibility testing revealed multidrug resistance in 44% (n = 239) of S. aureus isolates with the highest resistance of 61% against penicillin. Resistance against ampicillin, streptomycin, and lincomycin was observed. Fewer S. aureus isolates were resistant to kanamycin and erythromycin, whereas the lowest number of resistant isolates was observed against chloramphenicol. A high prevalence of S. aureus in the farm environment and milking equipment suggested the cross contamination of potentially enterotoxin-producing and multidrug-resistant S. aureus to raw milk. Therefore, good hygiene practices should be enforced to avoid foodborne and zoonotic infections.

Detection of bacteria of the genus Salmonella in meat from north-western Croatia

Salmonellosis is one of the most common food-borne zoonoses, and the most common source of infection for humans is meat and meat products. In 2023, 1125 samples of portioned meat (chicken, pork, beef) were tested in butcher shops in five districts of northern Croatia. The samples were tested for the presence of bacteria of the genus Salmonella, which were isolated in 88 (7.82%) samples. Salmonella was isolated from 604 chicken meat samples in 69 (11.4%) samples, from 319 pork samples in 10 (3.1%) samples and from 202 beef samples in 9 (4.5%) samples. Serological typing identified S. Infantis in 60 (87%) isolates from chicken meat samples, S. Mbandaka in 6 (8.7%) and S. Enteritidis in 3 (4.3%) samples. In pork, S. Derby was identified in 2 (20%) isolates, S. Typhimurium, S. Typhimurium (monophasic), S. London and S. Rissen in one isolate each (10%). In beef, S. Bovismorbificans was detected in 5 (55.6%) and S. Muenster in one (11.1%) isolate. Salmonellosis can be an economic problem due to the damage it causes in intensive production, but also a significant public health challenge as it spreads into the environment through the consumption and handling of contaminated meat in slaughterhouses, food processing and retail facilities. The implementation of appropriate hygiene measures and good hygiene practices from farms and slaughterhouses to butchers could help to reduce the contamination of meat with bacteria of the genus Salmonella.

Oral health-related beliefs among a sample of pregnant women in Southwestern Ontario: a descriptive study

IntroductionUnfavorable beliefs about oral health and dental treatment during pregnancy can lead to the avoidance of dental care and the underutilization of dental services, adversely affecting adherence to good oral hygiene practices and, consequently, the health of the fetus. This study investigated the commonly held oral health beliefs among pregnant women in Southwestern Ontario, Canada.MethodsParticipants were recruited from the Family Medicine Obstetrics Clinic in London, Ontario, Canada. Eligible participants were pregnant women aged 18 or older, excluding those unwilling to participate. Participants completed a 33-item self-administered questionnaire, including three open-ended questions about oral health beliefs and their impacts on pregnancy, which were analyzed for this study. Thematic analysis in NVivo identified key patterns, while analysis determined the most common beliefs and the degree of diversity in responses. Responses were categorized into sub-themes, and the frequency and percentage of each category were calculated.ResultsA total of 130 participants met the inclusion criteria. Among them, 40.7% (n = 46) believed that oral health impacts their child's health, 48.2% (n = 53) believed that dental treatment affects fetal health, and 64.4% (n = 76) believed that pregnancy influences their oral health. Many beliefs regarding oral health during pregnancy regarded infection risks. Participants held negative beliefs about the effects of antibiotics, analgesics, and dental x-rays during pregnancy. Common beliefs about the impacts of pregnancy on oral health included developing conditions, such as tooth sensitivity, caries, and gingivitis, as well as a loss of minerals to the fetus.ConclusionThis study revealed important misconceptions and concerns about oral health and dental treatment among pregnant women in Southwestern Ontario. The findings highlighted the need for enhanced oral health education for pregnant women to address these misconceptions and promote proper care during pregnancy. Healthcare providers are encouraged to focus on dispelling myths, emphasizing the safety of necessary dental treatments, and reinforcing the significance of maintaining good oral health for maternal and fetal well-being.

Shiga toxin-producing Escherichia coli in the milk production chain: Evaluation of virulence genes and clonal diversity of O157:H7 strains

Microbial contamination of milk and dairy products is a significant issue due to sensory changes and the risk of foodborne diseases. Shiga toxin-producing Escherichia coli (STEC), particularly the O157:H7, are major pathogens transmitted by dairy products. This study aimed to evaluate the microbiological quality of bovine milk at various stages of the production chain in a dairy cooperative and its suppliers in Rio de Janeiro, Brazil. Additionally, the presence of STEC in milk and faeces from dairy cattle was investigated, along with the isolation of STEC O157:H7 strains and the evaluation of virulence genes and clonal diversity. These findings were compared with previously isolated STEC O157:H7 strains from the same region. A total of 100 raw milk samples (54 farm gallon (FG) samples, 25 community bulk tank milk (CBTM) samples, 14 isothermal car-tanker milk (ICTM) samples, and 7 industry tank milk (ITM) samples) and 10 pasteurized milk samples, along with 63 bovine faeces samples, were analysed. The stx gene, a marker for STEC, was detected in 65% of raw milk samples and 88.9% of faecal samples, indicating a high risk of contamination throughout the production chain. None of the pasteurized milk samples tested positive for the stx gene. The prevalence of stx in faeces and raw milk underscores the need for rigorous controls to prevent contamination. While pasteurization was effective, the microbiological quality of raw milk remained unsatisfactory, highlighting the importance of good hygiene practices and continuous monitoring to ensure dairy safety.

Evaluation of the antimicrobial activity of chemical and herbal toothpastes on selected clinical microbial oral flora

Background: Microbes are most commonly found associated with oral diseases. Globally, researchers along with the world Health Organization (WHO) suggested that this could be due to poor oral health and encourage all individuals to practice good oral hygiene using daily oral health products. The study aimed to determine the antimicrobial effects of toothpastes, as acclaimed by the manufacturers, to selected microbial flora involved in oral infections. Methodology: The antimicrobial activity of 6 toothpastes (3 herbal and 3 chemical) was tested against 3 clinical microbial isolates; Staphylococcus aureus, Escherichia coli and Candida albicans, with minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) of each toothpaste determined for each microbial isolate using the broth dilution method. Results: Colgate exhibited the highest inhibitory activity against S. aureus with respective MIC and MBC of 125mg/ml and 125mg/ml, followed by Oral-B with MIC and MBC of 125mg/ml and 500mg/ml, Dabur herbal with MIC and MBC of 250mg/ml and 500mg/ml, and Longrich with MIC of 500mg/ml and MBC of 1000mg/ml. Colgate and CloseUp exhibited highest inhibitory activity against E. coli with respective MIC and MBC of 125mg/ml and 500mg/ml, followed by Dabur herbal with MIC of 500mg/ml but no MBC. Colgate exhibited the highest inhibitory activity against C. albicans with respective MIC and MBC of 125mg/ml and 500mg/ml, followed by CloseUp with MIC of 500mg/ml, Longrich with MIC of 500mg/ml and MBC of 1000mg/ml, and oral-B with MIC of 500mg/ml but no MBC. Longrich and Oral-B exhibited no MIC/MBC against E. coli while Gavia charcoal exhibited no MIC/MBC against all the 3 microbial isolates at the concentrations used in the assay.Conclusion: The results obtained showed that chemically formulated toothpastes (Colgate, CloseUp and Oral-B) had higher inhibitory activity on microbial isolates than herbal toothpastes (Longrich, Dabur herbal and Gavia charcoal). This supports the manufacturers claim for the chemical toothpastes used, however, the herbal toothpastes showed little or no inhibitory effects on the microbial flora.

Detection of the CTX-M Gene Associated with Extended-Spectrum β-Lactamase (ESBL) in Broiler Chickens in Surabaya Traditional Markets

A common indicator used to examine the frequency and distribution of antibiotic resistance against other enteric bacteria in humans and animals is the commensal enteric bacterium, Escherichia coli. The transmission of plasmids harboring ESBL enzymes, primarily generated by E. coli, is the cause of this resistance. The purpose of this study was to identify the CTX-M gene in ESBL-producing E. coli from broiler chicken cloacal swabs in traditional Surabaya markets. The samples used were 96 cloacal swabs from broiler chickens in the traditional markets of Dukuh Kupang, Keputran, Pacar Keling, and Pucang. The antibiotic disks used in this study belonged to five different antibiotic classes; they are aztreonam (monobactam), chloramphenicol (phenicol), kanamycin (aminoglycoside), ciprofloxacin (fluoroquinolone), and tetracycline (tetracycline). Presumptive ESBL strains were then molecularly screened for the presence of CTX-M gene. Results revealed that out of the 96 chicken cloacal swab samples collected, 58 (60.42%) were positive for E. coli based on morphological culture, Gram staining, and biochemical tests. Additionally, 15 out of the 58 E. coli isolates recovered from broiler chicken cloacal swabs were multidrug-resistant (MDR) while 7 of E. coli isolates harbored CTX-M gene. Conclusively, this study has shown that broiler chickens sold in traditional Surabaya markets harbor MDR E. coli which possess CTX-M gene. Conditions in traditional markets with low levels of cleanliness and chickens placed close together can spread resistance genes with serious public health consequences. Therefore, it is imperative to observe good hygienic practices in Surabaya traditional markets in order to curtail the spread of MDR bacterial pathogens in the food chain.

Assessing foodborne outbreak risks in Chinese households: A national survey analysis of pork handling practices

ObjectiveThis study aimed to assess the risk of foodborne outbreaks associated with household food handling practices in China and identify the consumer groups that are at higher risk for foodborne outbreaks. MethodsA national survey of household pork handling practices was conducted in China. The risk of foodborne outbreaks stemming from consumers’ improper handling practices was assessed utilizing the Weighted Harmonic Outbreak Prevention Index (WHOPI). The index categorized these practices into three levels of good hygienic practice (GHP): low (WHOPI≤0.35), medium (WHOPI: 0.36–0.70), and high (WHOPI>0.7). Logistic regression analyses were used to identify groups at higher risk for foodborne outbreaks. ResultsA total of 2730 households from seven provinces in mainland China were analyzed. Based on WHOPI, only 0.4 % of households demonstrated a high level of GHP, while 55.4 % showed a low level of GHP. The primary non-conforming stage was separation practices, followed by cooking and purchasing practices. Nearly two-thirds of households (64.8 %) didn’t have a separate cutting board for raw meat, and 44.9 % of them claimed to use the same board to handle ready-to-eats afterward. Logistic regression indicated more attention is required for those living in southern and rural areas, working in non-public institutions, possessing lower levels of education, and being single or widowed. ConclusionThe household food handling practices of Chinese consumers involve serious food safety risks. Education programs and interventions concerning safe handling practices in households are urgently needed.

Comprehensive evaluation of deep neck infections: A retrospective analysis of 111 cases.

Our study will analyze patients' clinical characteristics, treatment strategies, and complications with deep neck infection (DNI) using their medical records for five years. The present study included 111 patients diagnosed with DNI in our clinic between January 2018 and March 2023. The patients' complaints at admission, sociodemographic characteristics, season of diagnosis, findings from laboratory tests, radiological imaging performed at the time of first diagnosis, abscess localization, medical and surgical treatment methods used, and complications developing during follow-up were retrospectively examined. The mean age of the patients included in the study was 38.51 ± 16.92 (6-87 years). There was a significant correlation between chronic disease, smoking behaviours, oral hygiene, and DNI among patients based on their sociodemographic characteristics and medical history (p < .005). DNI development did not differ by season (p > .005). Physical examination findings predominantly revealed neck masses (39.6%) and peritonsillar abscesses (32.4%), and patients with peritonsillar abscesses had a shorter length of hospital stay than those with other localizations. No severe complications occurred during the clinical follow-up. Chronic diseases, smoking, and poor oral hygiene are the primary risk factors for developing DNIs. If an abscess is located in a critical area, it may require extended hospitalization and surgery under general anesthesia. Therefore, addressing these risk factors and encouraging good oral hygiene practices are crucial to preventing DNIs and reducing the need for intensive treatment.

Exposure assessment and semi-quantitative risk analysis of histamine in tuna and tuna-like fish from Indonesia

This study aimed to investigate histamine exposure associated with consumption of fresh tuna and tuna-like species in West Java, and to estimate risk of Scombroid Fish Poisoning (SFP) in Indonesia. A range of species, including tuna (Thunnus spp.), bullet tuna ( Auxis sp.), and skipjack ( Katsuwonus pelamis ) were collected from local markets and fish landing sites. Subsequently, histamine concentrations were determined using NMR analysis and exposure was calculated in mg/day for toddlers, children, and adults. The results showed that skipjack had the highest histamine exposure for all age groups, followed by bullet and regular tuna. The highest EDI for histamine was from skipjack consumption, accounting for 38.67; 37.77 and 20.74 percentage of exposure for toddlers, children and adults, respectively. These values are below the defined thresholds levels (ARfD), indicating no potential risk of acute health effect. Cooked bullet tuna and skipjack were estimated to cause similar illnesses, accounting for 6–7 cases per 100,000 individuals, which was higher than cooked tuna at 1–2 cases per 100,000 individuals. Considering the preparation of raw tuna in restaurants following Good Hygienic Practices (GHP), the predicted annual cases decreased significantly to 4–5 cases per million individuals. This risk estimation only considered histamine levels in fresh fish, without including data from fish preparation. Therefore, further studies were recommended to estimate the risk level in raw/fresh tuna and similar species before consumption.

Assessment of Lactococcus Cremoris preparations for the pre- and post-milking teat disinfection

Good hygienic milking practices including the disinfection of the cow teat skin before and after milking aimed at preventing the occurrence of new intramammary infections (IMI) in dairy cows. This practice is generally performed using disinfectants, and in the current context of attention to the emergence of resistances, it is of greatest interest to evaluate alternative solutions that can expand treatment options. We assessed the efficacy of a pre-dipping and a post-dipping product based on the bacteriocin-containing culture of Lactococcus cremoris strain FT27, as compared to commercial disinfectants. FT27 was selected for the bactericidal activity in vitro against food pathogens. In the present study, it also revealed a high bactericidal activity against the main mastitis pathogens, most likely related to Nisin A production, according to genomic and proteomic analysis. The lactococcus-based preparations were applied in two commercial dairy farms in Northern Italy. Overall, 298 dairy cows were enrolled, 141 in the treated group (TR), and 157 in the control group (CTR). The cows were sampled at quarter level every two weeks for 3 months. During the trial, all cows showed a good health status. The hygiene level for udder, flanks and legs was generally good (on average < 3 score); the udder hygiene was significantly worse (P < 0.01) in the CTR group. The teat apex hyperkeratosis was overall low (on average < 2 score). We recorded no significant differences between the two experimental groups in the Somatic Cell Count (SCC) values and the bacteriological results. The overall frequency of new IMI was low, ranging 0.6 − 0.5% for S. aureus in the TR or CTR group respectively, to 2.6–4.4% for NASM. Regarding Str. spp., the new IMI accounted for 1.7% or 1.9% in the TR or CTR group, respectively. Notably, the incidence of S. aureus new IMI did not increase during the study, even though neither of the two herds segregated the positive cows. The non-inferiority test showed that the Lactococcus-based pre- and post-dipping products had an efficacy comparable to proven commercial disinfectants in maintaining udder health and preventing new IMI, thus representing a possible alternative to current teat dip products.

Content quality and reliablity of YouTube™ videos as a source of information about good oral hygiene practices in adults.

Good oral hygiene is crucial for preventing dental caries and periodontal diseases. However, proper and regular application of oral hygiene practices requires adequate knowledge. In recent years, the internet has become one of the most popular places to find health-related information, necessitating studies that analyze the quality of the content available online. The purpose of the present study was to analyze the content quality and reliability of YouTube™ videos on the topic of adult oral hygiene practices and to guide oral health care professionals who use this platform for patient education. A YouTube™ search was performed of the most frequent search term, 'dental hygiene'. A total of 150 videos were screened, and 51 were included in the final study. The characteristics, sources, and content of the videos were analyzed using the Global Quality Score (GQS) and DISCERN reliability indices. The IBM SPSS 25 program was used for statistical analyses. Most of the included videos were uploaded by oral health care professionals (63%). GQS revealed only 17.6% of the videos were excellent quality whereas 23.5% of them were poor quality. In the content analysis, 62.7% of the videos were deemed moderately useful. Video duration, total content score, and interaction indices were all significantly higher in the useful and very useful groups compared to the slightly useful group (p = 0.020, p < 0.001, p = 0.040). GQS had a positive, low-medium statistically significant correlation with both video duration and total content scores (r = 0.235, r = 0.517; p < 0.05). DISCERN score also had a positive, low-medium statistically significant correlation with total content score (r = 0.500; p < 0.05). The study concluded that most YouTube™ videos on oral hygiene practices for adults are moderately useful. When using YouTube™ for patient education, oral health care professionals and organizations should be aware of low-quality videos and seek out accurate, useful videos. There is also a need for quality videos with expanded oral health content.

Multidrug-Resistant Proteus mirabilis and Other Gram-Negative Species Isolated from Native Egyptian Chicken Carcasses.

Poultry carcasses may be reservoirs for the zoonotic transmission of antimicrobial-resistant bacteria to humans and pose a major public health hazard. During the isolation of Salmonella from poultry and other foods, many of the presumptive typical Salmonella colonies on xylose lysine deoxycholate (XLD) agar were found to lack the invA gene, which is the specific target gene for Salmonella spp. Therefore, the current study aimed to estimate the prevalence and antimicrobial resistance profiles of extensively drug-resistant invA-negative non-Salmonella isolates recovered from native Egyptian chicken carcasses as presumptive Salmonella colonies on XLD agar. The non-Salmonella isolates were detected in 84% (126/150) of the examined native Egyptian chicken carcasses and classified into five genera, with prevalence rates of 64% (96/150), 14% (21/150), 6.7% (10/150), 3.3% (5/150), and 1.3% (2/150) for Proteus, Citrobacter, Shigella, Pseudomonas, and Edwardsiella, respectively. One hundred and ninety-five invA-negative, non-verified presumptive Salmonella isolates were recovered and classified at the species level into Proteus mirabilis (132/195; 67.7%), Proteus vulgaris (11/195; 5.6%), Citrobacter freundii (26/195; 13.3%), Shigella flexneri (8/195; 4.1%), Shigella sonnei (6/195; 3.1%), Shigella dysenteriae (3/195; 1.5%), Pseudomonas fluorescens (6/195; 3.1%), and Edwardsiella tarda (3/195; 1.5%). All (195/195; 100%) of these isolates showed resistance against cefaclor and fosfomycin. Additionally, these isolates showed high resistance rates of 98%, 92.8%, 89.7%, 89.2%, 89.2%, 86.7%, 80%, 78.5%, 74.4%, and 73.9% against cephalothin, azithromycin, vancomycin, nalidixic acid, tetracycline, sulfamethoxazole/trimethoprim, cefepime, gentamicin, cefotaxime, and ciprofloxacin, respectively. Interestingly, all (195/195; 100%) of the identified isolates were resistant to at least five antibiotics and exhibited an average MAR (multiple antibiotic resistance) index of 0.783. Furthermore, 73.9% of the examined isolates were classified as extensively drug-resistant, with an MAR index equal to 0.830. The high prevalence of extensively drug-resistant foodborne Proteus, Citrobacter, Shigella, Pseudomonas, and Edwardsiella isolated from native chicken carcasses poses a great hazard to public health and necessitates more monitoring and concern about the overuse and misuse of antibiotics in humans and animals. This study also recommends the strict implementation of GHP (good hygienic practices) and GMP (good manufacturing practices) in the chicken meat supply chain to protect consumer health.

Effects of health education intervention on menstrual hygiene knowledge and practices among the adolescent girls of Pokhara Metropolitan, Nepal.

Poor menstrual hygiene practices are one of the major public health problems in Nepal. Due to persistent taboos and socio-cultural constraints, adolescent girls are often unaware of scientific facts, knowledge, and practices related to menstrual hygiene. This paper aims to assess the effects of health education intervention on menstrual hygiene knowledge and practices among adolescent girls in Pokhara Metropolitan, Nepal. A true experimental study was conducted in two government basic schools in Pokhara Metropolitan, Nepal. The study population was adolescent girls who had attended the menarche. Firstly, a pretest with the help of a self-administered questionnaire was done to find out the socio-demographic information, knowledge and practices of menstrual hygiene. Next, health education sessions were conducted among the intervention group. Finally, after one month of intervention, a post-test was conducted among the intervention and non-intervention group. Data analysis was done through descriptive and inferential statistics. The findings showed significant improvement in the knowledge and practice level of adolescent girls on menstrual hygiene after health education intervention. Participants in the intervention group showed a significant increase in knowledge scores from 10.0% to 67.0%, while the non-intervention group remained unchanged at 7.5%. Good menstrual hygiene practices scores in the intervention group increased significantly from 22.5% to 67.0%, whereas the non-intervention group saw a slight rise from 20.0% to 22.5%. Regarding observed practice scores in menstrual hygiene, significant improvement was observed in the intervention group (45.0% to 100.0%) in contrast to the non-intervention group (25.0% to 27.5%). This study highlights the crucial role of school health education interventions in promoting menstrual hygiene among adolescent girls. It emphasizes the importance of comprehensive educational programs tailored to early teenage girls, addressing timing, content, and delivery methods alongside ensuring the availability of Water, Sanitation and Hygiene (WASH) facilities.

Characterization of toxigenic genes of Bacillus cereus strains isolated from different spices sold in Algeria.

Many cooked foods are prepared with spices and dried herbs; these can be contaminated by several types of microorganisms, including aerobic spore-forming bacteria. The Bacillus cereus group is very widespread in nature and is known among the common food contaminants. They are involved in food poisoning, causing two types of syndromes, diarrheal and emetic. The aims of the present work were to determine the prevalence of toxigenic Bacillus cereus spores in spices and herbs marketed in the Laghouat area and to identify their toxigenic genes via PCR. Among the 191 samples, 14.13% were determined to be B. cereus, with concentrations ranging from 2.52 to 5.82 log cfu/g, where the highest level of contamination was observed in allspice and ginger. Moreover, entFM (100%), nhe (88.23%) and cytK (70.58%) were the most frequently identified toxin genes, whereas hbl (23.52%) was less common, and no emetic toxin-encoding gene (cesB) was found in any of the samples. Considering the results of the present study, the B. cereus microbial load and toxin gene profiles of spices show that spices have potential for public health in Algeria. In this context, it is crucial to guarantee the microbiological safety of spices by respecting good hygiene practices, eliminating bacterial spores and toxin production via sterilization and using appropriate packaging for these products.

Microbiological and nutritional assessment of ‘&lt;i&gt;ncha iwu&lt;/i&gt;’ (edible emulsion) vended in selected markets in Umunneochi Lga, Abia State, Nigeria

‘Ncha iwu’ is commonly used as a sauce in the preparation of ready-to-eat African salad, a wellknowndelicacy among the Igbo tribe in Nigeria. A total number of fifteen (15) samples of ‘ncha iwu’ were randomly purchased from three (3) vendors in Orie Ngodo and Eke Eziama market in Umunneochi Local Government Area of Abia state. The microbiological quality, proximate composition, and mineral content of the samples were determined using Standard Methods. ‘Ncha iwu’ prepared in the laboratory served as the control. The results showed that total bacterial, Staphylococcal, Coliform and fungal counts of the samples ranged from 3.81-4.37, 2.0-3.58, 3.0-3.8, and 2.0-3.0 log10 CFU/g, respectively. The bacterial species isolated and frequency of occurrence were Staphylococcus aureus (28 %), Klebsiella spp. (18 %), Pseudomonas spp. (18 %), Escherichia coli (18 %) while the fungal species were Penicillium spp. (50 %), Aspergillus spp. (40 %), and Candida spp. (10 %). Proximate analysis indicated that ‘ncha iwu’ contains ash (63.93%), moisture (15.88 %), fibre (8.99 %), lipid (7.70 %), protein (3.50 %) and carbohydrate (0.0 %) while minerals content include Fe (3.679 mg/g), Mg (1.055 mg/g), K (1.054 mg/g), Ca (1.030 mg/g), Mn (0.469 mg/g) and Na (0.222 mg/g). Although ‘ncha iwu’ contains beneficial nutrients, majority of the commercial samples were contaminated with potential pathogenic microorganisms which is a public health concern unlike the control. This is as a result of poor handling by the producers and vendors. Good hygienic practices by the handlers, proper packaging and storage of ‘ncha iwu’ will reduce the microbial contamination of the product. Hence, adequate public health awareness campaign, training on food safety, sanitation and hygenic practices should be provided to the local processors and vendors of ‘ncha iwu’.

Assessment of Sleep Quality and Duration of Medical Students in Enugu State College of Medicine

Sleep is a physiological behaviour that occurs in all animal species forming about one – third of human life and is essential for survival. Prolonged sleep deprivation leads to severe physical impairment usually accompanied by cognitive loss and can even lead to death. Sleep is a naturally recurring state of mind and body, characterized by relatively inhibited sensory activity and reduced interactions with surroundings, altered consciousness, reduced muscle activity and inhibition of nearly all voluntary eye muscles. Therefore, this study is aimed at investigating the impact of various sleep duration among students and the effect on their academic performance. Using a simple random method of sampling, questionnaires were physically distributed among medicine and surgery students of ESUT College of medicine and 265 students participated. Statistical analysis was done using the Statistical Package for the Social Sciences (SPSS) version 23 (SPSS Inc., Chicago, IL) with a value of &lt;0.05 considered significant. From the analysis of the data retrieved from the questionnaire, it was observed that during a regular school week, majority of students (27.5%) obtained 6 hours of sleep, while the night prior to an examination, of students (27.9%) obtained 4 hours of sleep. Also, 68.7% of students believe that insufficient sleep has a negative impact on memory consolidation, while 31.3% believes otherwise. In conclusion from the results, the study suggests that students should be educated regarding good sleep hygiene practices as this has a positive effect on their academic performance.

Assessment of Microbial Contamination and Hygiene Practices of Okra Powders in Public Markets of Yamoussoukro

Background: Okra is one of the most consumed fruit vegetables by Ivorians either fresh or powdered. However, due to a lack of supervision, okra powders are sold under conditions that often leave something to be desired. Objectives: This study aims to assess the level of microbial contamination of okra powders sold in public markets, with a view to preventing any potential health risks for consumers. Methodology: The experimental method is based on a survey within the markets of the city of Yamoussoukro in order to describe the conditions of sale. Samples of okra powders sold in these markets were analyzed. Acquired Results: The survey showed that, most marketers sell their product beyond 10 days. Additionally, okra powders are sold in plastic containers, uncovered. In addition, the analyzes reveal the absence of Salmonella spp. but the presence of yeasts, molds, Staphylococcus aureus and Escherichia coli whose loads varying from 3.5. 103a ± 0.16.103 to 4.8.103a ± 0.49.103 CFU/g, 1.5.104b ± 0.28.104 to 3.2.103a ± 0.32.103 CFU/g and 3.3.103a ± 0.17.103 to 8.103a ± 0.91.103 CFU/g. However, all the okra powders analyzed present an unsatisfactory microbiological quality. Conclusion and Outlook: To avoid any health risk for consumers, traders must be supervised, organized and made aware of good hygiene practices.
