ASSESSMENT OF THE QUALITY AND NUTRITIONAL VALUE OF FIRST GRADE WHEAT FLOUR FROM DIFFERENT MANUFACTURERS

Despite the sufficient volume of wheat flour production, there are low-grade, falsified products on the consumer market, and flour with low baking properties is also found. In this regard, the purpose of the research was to assess the quality and nutritional value of first grade baking wheat flour from different manufacturers. Studied: organoleptic, physico-chemical, hygienic quality indicators, the content of dietary fiber, mineral elements and vitamins. It was determined that all flour samples in terms of organoleptic indicators met the regulated requirements of GOST 26574-2017, in terms of the amount of pesticides and mycotoxins - the norms of SanPiN 2.3.2.1078-01 and TR TS 021/2011. Flour produced by IP A.A. Mikhailyuta (Omsk region, Kormilovsky district, Pobeditel village) met the requirements of the current standard for first-class products in terms of physical and chemical parameters, was safe in terms of the level of heavy metals within the framework of current regulatory documents, and had a complete macro- and micronutrient composition. Flour produced by JSC “Shadrinsk combine of bread products” (Kurgan region, Shadrinsk) turned out to be unsafe in terms of Pb content, the excess of which was more than 3 times, which is unacceptable. Flour produced by KFH V.V. Malyutov (Ivanovo region, Puchezhsky district, Poperekovo village) did not meet the requirements of GOST 26574-2017 in terms of such indicators as the quantity and quality of gluten, ash content, which may indicate its falsification.

Milk Quality Parameters of Raw Milk in Ecuador between 2010 and 2020: A Systematic Literature Review and Meta-Analysis.

With the objective of evaluating the quality parameters of raw milk in Ecuador between 2010 and 2020, a systematic review and meta-analysis of 73 studies on raw milk produced in different regions of Ecuador was performed. Under the random effects model, effect size and heterogeneity were determined vs. climatic region both among analyses and studies, with Cochran’s Q, I2 and Tau (π) statistics. For all the variables, it was observed that there was great heterogeneity (I2 > 90%) among the studies; additionally, it was found that climatic region had an influence only among the variables arsenic, mercury, pH and total solids, and it was greater in the coastal region than the Inter-Andean region. The mean values of the physicochemical characteristics of the milk (titratable acidity, ash, cryoscopy, fat, lactose, pH, protein, non-fat solids and total solids) in the great majority of these studies were within the range allowed by Ecuadorian regulations. As for the hygienic quality of raw milk (total bacterial count, somatic cell count and presence of reductase), although the mean values were within those determined by local legislation, it should be noted that the range established by Ecuadorian regulations is relatively much higher compared to other regulations, which possibly means that there is a high presence of bacteria and somatic cells in raw milk. Finally, the presence of several adulterants (added water) and contaminants (AFM1, antibiotics and heavy metals) was confirmed in the milk, in addition to other substances such as eprinomectin, zearalenone and ptaquilosides, whose presence can be very dangerous, because they can be hepatotoxic, immunotoxic and even carcinogenic. In conclusion, there is great variability among the studies reviewed, with the physicochemical characteristics being the most compliant with Ecuadorian legislation; the hygienic characteristics, adulterants and contaminants of raw milk require greater attention by producers and local authorities, so that they do not harm the health of consumers and the profitability of producers in Ecuador.

Application of Edible Coating Based on Liquid Acid Whey Protein Concentrate with Indigenous Lactobacillus helveticus for Acid-Curd Cheese Quality Improvement.

Edible coatings as carriers for protective lactic acid bacteria (LAB) can enhance hygienic quality to dairy products. Thus, the aim of this study was to improve the quality of artisanal acid-curd cheese by applying liquid acid whey protein concentrate based edible coating with entrapped indigenous antimicrobial Lactobacillus helveticus MI-LH13. The edible fresh acid-curd cheese coating was composed of 100% (w/w) liquid acid whey protein concentrate (LAWPC), apple pectin, sunflower oil, and glycerol containing 6 log10 CFU/mL of strain biomass applied on cheese by dipping. The cheese samples were examined over 21 days of storage for changes of microbiological criteria (LAB, yeast and mould, coliform, enterobacteria, and lipolytic microorganism), physicochemical (pH, lactic acid, protein, fat, moisture content, and colour), rheological, and sensory properties. The coating significantly improved appearance and slowed down discolouration of cheese by preserving moisture during prolonged storage. The immobilisation of L. helveticus cells into the coating had no negative effect on their viability throughout 14 days of storage at 4 °C and 23 °C. The application of coating with immobilised cells on cheeses significantly decreased the counts of yeast up to 1 log10 CFU/g during 14 days (p < 0.05) of storage and suppressed growth of mould for 21 days resulting in improved flavour of curd cheese at the end of storage. These findings indicate that LAWPC-pectin formulation provided an excellent matrix to support L. helveticus cell viability. Acting as protective antimicrobial barrier in fresh cheeses, this bioactive coating can reduce microbial contamination after processing enabling the producers to extend the shelf life of this perishable product.

Karakteristik Pasien Demam Tifoid Di Rumah Sakit Ibnu Sina Makassar

Typhoid fever is an infectious disease caused by the bacterium Salmonella enterica serovar Typhi (S. Typhi). It is estimated that between 350-850 per 100,000 population per year. This disease attacks all ages, some studies argue that the male sex suffers from typhoid fever more because it is influenced by work, environment, and eating and drinking habits. This disease is an endemic disease that is still a health problem in Indonesia due to the lack of deep quality of personal hygiene and environmental sanitation. This study aims to determine, classify and describe the characteristics (age, gender, type of therapy, length of treatment) in typhoid fever patients at Ibnu Sina Hospital Makassar in 2019. This study is a descriptive observational study with a retrospective approach. The population in the study amounted to 490 samples. The sample of this study is secondary data, namely, by taking medical record data, sampling using purposive sampling method and the sample size is obtained as many as 82 samples. ie 15 – 24 years (39.0%), based on the type of therapy, namely type 1 therapy (92.7%) where this type of therapy used 1 type of antibiotic, based on the length of treatment 7 days (90.2%). The conclusion is that the number of typhoid fever sufferers is 82 people with the most gender being male, the highest age is 15-24 years, the most use of therapy using one type of antibiotic is accompanied by the longest length of treatment, which is an average of fewer than 7 days.

VARIABILITY OF SELECTED PARAMETERS OF HYGIENIC QUALITY OF FRESH, MARINATED AND GRILLED POULTRY MEAT IN RELATION TO ITS STORAGE CONDITIONS

The aim of research was to verify scientifically variability of selected parameters of hygienic quality of fresh (A), marinated (B-E) and grilled (G) poultry meat in relation to its storage conditions. Marinated meat was kept under various conditions (12 hours and 48 hours at a temperature of 0 to 4 °C and 5 to 8 °C) until it was heat-treated. Using microbiological and physico-chemical methods, poultry meat was analysed in fresh, marinated, as well as grilled state. During the experiment period, water activity, pH, salt, and fat content, but also TVC - total viable count of microorganisms, coliforms, MFF - microscopic filamentous fungi and yeast were analysed. The value of aw ranged from 0.92 (EG) to 0.99 (AG and D). The range of mean pH values ranged from 5.82 to 6.15. The salt content was lowest in fresh meat (0.16 g/100g), in samples of marinated meat it ranged from 0.38 to 0.47 g/100g. Thus, in neither case was the maximum permitted salt content (1.3 g/100g) exceeded. The difference between the lowest and the highest fat content was very observable. The lowest value of fat content 3.40 g/100g was obtained in the sample AG. On the contrary, the highest fat content (10.24 g/100g) was detected in the sample D. The average TVC value in fresh poultry meat was 4.01 log CFU/g. In marinating process, the value increased to 4.21 log CFU/g (12 hours, 0 to 4 °C) and to 4.65 log CFU/g (48 hours, 5 to 8 °C). Microorganisms were present in number of less than 1.101 CFU/g in grilled meat. The number of microscopic filamentous fungi and yeasts was low in fresh meat and marinated meat (<4.101 CFU/g). After grilling they were not detected. Coliforms indicating the cross contamination were not present in the samples. All the obtained results were statistically evaluated. The data were processed to the analysis of variance (ANOVA) in the general linear models (GLM), Scheffe’s test and Pearson correlation coefficients (rxy).

Is alfalfa hay an alternative to meadow hay in equine nutrition?

Roughage alternatives for equine nutrition must be found due to the increasing climatic challenges. The aim of this study was to examine the nutrient composition and feed hygiene of alfalfa hay in comparison to meadow hay and to investigate the acceptance, weight development and faecal quality of broodmares fed alfalfa hay. The feed used was examined for nutrient content and hygiene status according to the standards of the Verband Deutscher Landwirtschaftlicher Untersuchungs- und Forschungsanstalten (VDLUFA). Twenty adult pregnant warmblood mares were fed in two groups (n=10) with a defined amount of alfalfa hay or meadow hay in a controlled study with a wash-out phase and subsequent crossing of the groups. Alfalfa hay intake was observed daily, and bodyweight was recorded weekly. On day 0 (T0) and day 28 (T28) of each study period, fresh faecal samples were collected and analyzed for pH, dry matter (DM) and short-chain fatty acids (SCFA). The hygienic quality of the alfalfa and meadow hay was slightly reduced (quality level II) on average. The intake of the alfalfa hay was carried out in all mares without backweighing. The median crude protein content of the alfalfa hay was 134 g/kg DM, the median calcium content was 13,9 g/kg DM and the median magnesium content was 1,50 g/kg DM. Horses fed alfalfa showed a significantly greater median percent weight gain of 3,25 % compared to hay-fed horses (1,68 %) (p.

Literature Study: Effectiveness of Scabies Treatment Using Natural Ingredients

The skin is the outermost organ that is often exposed to the external environment, which can cause skin diseases, one of which is scabies. Scabies is caused by the mite Sarcoptes scabiei var hominis and its products. often found in densely populated environments, such as Islamic boarding schools and communities with poor personal hygiene quality or tend to be poor, and low economic status. For management, administration of drugs is generally topical to kill the mites that cause this disease. However, it has limitations, such as the relatively expensive price, so that alternative medicine materials with relatively cheaper costs are needed, namely medicines made from plants. The purpose of this study was to evaluate publications on the effectiveness of scabies treatment using natural ingredients. Methods: This study uses a literature study method in obtaining information or data from journals and research documents. The results of the literature study indicate that the use of traditional medicine is effective in the healing process of scabies. The use of traditional medicine is effective in curing scabies but as a complement to the use of topical drugs.

Effects of attribute bonuses on milk quality in 164 dairy farms of Ubaté and Chiquinquirá (March 2012 – March 2018)

Introduction: Given that milk price fluctuations have an impact on local milk production, which affects a vital sector for the economy due to its contribution to GDP and the generation of direct and indirect jobs, this study seeks to establish what has been the effect of monetary incentives on the quality of milk from 164 dairy farms in the Ubaté and Chiquinquirá valley between March 2012 and March 2018. Methodology: To answer this question, it is hypothesized that the implementation of the quality payment scheme described in Resolution 0017 of 2012 positively affected the values with which the hygienic quality of milk is measured. To test this hypothesis, a mixed approach methodology was used (qualitative and quantitative), descriptive, correlational and explanatory, non-experimental, using a longitudinal model of panel data for the sample of milk producing farms. Results: The study allowed establishing that the current quality payment scheme (QPP), the lagged QPP and the price paid to the producer (PPP) have significant effect on decreasing milk microbiological counts, the price per gram of solids and the amount of solids per liter are significant increase milk microbiological counts. Conclusions: It was possible to conclude that it is advisable to increase the participation of bonuses per CFU on the total price, this would incentivize a faster improvement of hygienic quality.

Microbiological Quality of Red Meat Offal Produced at Australian Export Establishments.

A national baseline study of offal hygiene was undertaken at 17 Australian export establishments. A total of 1756 samples of different offal types were analysed for aerobic plate count (APC), generic Escherichia coli, and coliform bacteria. Average APC values varied from 1.51 to 5.26 Log10 CFU/g, depending on species and offal type. The average APC on beef, sheep, lamb, and goat offal was 3.25, 3.38, 3.70, and 2.97 Log10 CFU/g, respectively. There is a small but significant difference in APC on offal sampled frozen (3.26 Log10 CFU/g) and offal sampled fresh (3.73 Log10 CFU/g). Escherichia coli prevalence on beef, sheep, lamb, and goat offal was 15.4%, 28.1%, 17.5%, and 39.3%, respectively. The number of E. coli on positive offal samples ranged from 1.42 to 1.82 Log10 CFU/g. While the quality of some offal approach that of muscle meat, the hygienic quality of red meat offal can be understood by considering the anatomical site from which it is harvested, the usual bacterial levels found at that site, the difficulty in hygienically removing the offal from the carcase, the process prior to packing, and the chilling method used.

Raw Milk for Provolone Valpadana PDO Cheese: Impact of Modified Cold Storage Conditions on the Composition of the Bacterial Biota

The raw milk for production of long-ripened, spicy type, Provolone Valpadana (PV) PDO cheese must be stored, refrigerated, and processed within 60 h from the first milking, according to European and Consortium regulations. Low-temperature storage conditions preserve the hygienic quality, but also reduce the diversity and content of dairy microbiota, which is important to define the characteristics and quality of raw milk cheeses. Eleven bulk, raw milk samples were stored, at laboratory level, under two different time/temperature conditions (i.e., 10 °C or 12 °C for 15 h, then cooled to 4 °C for 45 h). The count of different bacterial groups and the diversity of bacterial communities were determined before and after storage by culture-dependent and DNA metabarcoding methods, respectively. The two-step cold storage conditions increased the mesophilic, psychrotrophic, lipolytic, and proteolytic bacterial load, without affecting the hygienic quality of milk. Among the 66 dominant and 161 subdominant taxa retrieved by DNA metabarcoding, Acinetobacter, Pseudomonas, and the lactic acid bacteria belonging to the genera Lactococcus and Streptococcus were present in almost all the raw milk samples, and their relative abundance was positively related with the total bacterial count. The storage conditions tested could be considered for eventual application in long-ripened PV cheese production to rationalize storage, transfer, and processing of raw milk.

Prevalence of Sleep Hygiene Awareness, Practices and Quality among Elementary School Students in Canada

Enough sleep is crucial for physical and emotional growth of kids and students. It has been noted that there is a progressive decline in bedtime as kids turn into teens, despite the fact that the need for sleep among students does not decrease. Teenagers need for sleep has been estimated as much as 9.2 h per day. Poor sleep has actually been noted to lead to poor diet regimen, excessive weight, stunted growth, psychological health concerns, as well as chemical abuse. Much as the need for sleep is an individual particular, approximately at least 8.3 hrs. of rest per evening is recommended for teens, to avoid excessive daytime drowsiness. High quality sleep is necessary for young professional athletes for making sure much better performance in psychomotor as well as cognitive activities, and for minimizing the chances of creating challenging factors for musculoskeletal discomfort. Detection of sleep disorders in adolescent complaining of sleeplessness is a day-to-day challenge for doctors and clients alike. The purpose of the research study was to assess the prevalence of sleep hygiene awareness, practices and quality among elementary schools students in Canada. The study was a literature based. The research discovered that a boost in the occurrence of difficulty in getting sleep and in too much screen time exposure and marginal increase in physical activity levels. In addition, teens exceeding 2-h everyday display time had 20% higher probabilities of reporting sleep-onset problems, while no association was discovered for physical activity. The study also discovered that a regular every night routine aids the body recognize that it is going to bed; this could consist of taking warm shower or bathroom, checking out a publication, or light stretches. Whenever feasible it is essential for the students to try to avoid emotionally distressing conversations and activities before attempting to sleep considering that maintaining a routine sleep timetable also on weekends keeps the timing of the body's body clock and also can aid you fall asleep and wake up much more quickly. Based on the finding, the research study concluded that the daily substances that students take, the medicines one takes, how long they sleep in a day and exactly how they choose to invest their nights can considerably influence their quality of sleep. Also a couple of mild adjustments can, in many cases indicate the difference between sound rest as well as a restless evening. Finishing a two-week rest diary can help one understand how their routines impact their sleep. The study suggested that teenagers must reserve no more than eight hrs. For sleep given that the suggested quantity of sleep for a healthy grownup goes to least 7 hrs. Keywords: Sleep Hygiene, Awareness, Sleep Quality, Sleep Disorder, Students

The effect of acute gamma radiation onto growth media for mother culture of a Volvariella mushroom

Potato Dextrose Agar (PDA) is a semicrystalline polymer made from amylopectin, agarose, and amylose, used in laboratories for Agar plate culturing for a multitude of fungal strains. The existing pretreatment method for the elimination of pathogenic bacteria, namely steam sterilization, has shown several drawbacks, including high cost, uneven heating due to temperature differentials and an inability to treat specimens volumetrically. These drawbacks are mitigated by gamma irradiation, being carried out in order to improve hygienic quality and germination control, retarding sprouting, also enhancing physical attributes of the food product. Present study investigates the growth and survival of pretreated potato dextrose agar (PDA) substrate with gamma irradiations, for doses ranging from 0 kGy (unirradiated) up to 20 kGy, particularly for Volvariella mushroom cultivation. The relative elemental composition of PDA substrate has been obtained through use of Energy Dispersive X-ray Analysis (EDX), identifying carbohydrate (53.35%), oxygen (45.29%) and 1.36% of mineral trace elements. Gamma irradiation doses to the PDA substrate of 0.5 kGy, 1 kGy and 1.5 kGy have been found to be associated with respective growth rates of 0.93 ± 0.03, 0.94 ± 0.02 and 0.89 ± 0.02 cm/day, the PDA becoming more amorphous and acidic with reduced viscosity at higher doses. The findings of this study could pave the way for a low-cost yet highly effective system for irradiation in mushroom, as well as offering a viable alternative to current conventional sterilizations, well suited to applications in food security.

From Nutritional Adequacy to Hygiene Quality: A Detailed Assessment of Commercial Raw Pet-Food for Dogs and Cats.

Simple SummaryAs alternative diets to processed pet food, raw meat-based diets (RMBDs) have received increasing attention in recent years. Commercial RMBDs consist mainly of raw meats, animal by-products, such as offal, and bones. Most RMBDs do not contain additives; therefore, they potentially pose a risk of nutritional imbalances to adults and, to a greater extent, growing animals. RMBDs are frozen ready-to-use products that are fed to pets after being thawed. Bacterial contamination of RMBDs is an area of concern, including the risk of spreading zoonotic diseases to humans. In this study, a detailed assessment of commercial RMBDs was performed in relation to nutritional adequacy and hygiene quality. The results showed that the tested products often provided deficient amounts of essential nutrients, were nutritionally unbalanced, and very rich in fat. They were also characterized by high microbial contamination, showing low hygiene quality. This study provides information that indicates the need for strict monitoring of the nutritional and microbiological quality of commercial RMBDs.Raw meat-based diets (RMBDs) are widely used as unconventional diets for dogs and cats at different life stages, despite concerns regarding nutritional adequacy and microbial contamination. The aim of this study was to evaluate both the nutritional and hygiene quality profile of RMBDs purchased in Germany. For this purpose, crude nutrients were assessed in 44 RMBDs and compared to declared values. In addition, selected minerals were determined in 31 RMBDs labelled as complete and compared to the minimum requirement (MR) for intended species and life stages. Aerobic colony count (ACC) and Enterobacteriaceae were used to assess the hygiene quality of 37 commercial RMBDs, while the presence of Salmonella spp. was examined in 10 products. Fat and protein content exceeded tolerated deviation from declared values in 33% and 45% of RMBDs, respectively. Each RMBD showed at least one concern regarding nutrient content. The RMBDs had high fat contents (mean 69, range 33–95 g/Mcal) that were negatively correlated with protein (r = −0.74, p < 0.0001). Considerable contaminations by ACC and Enterobacteriaceae were found (2.61 × 108 ± 3.63 × 108 and 3.61 × 106 ± 8.39 x106 CFU/g, respectively). A higher count of Enterobacteriaceae was detected in a frozen RMBDs made of poultry or carcasses from different animals, compared to the thawed counterpart (p = 0.003), as well as compared to other sources, such as beef, horse, and lamb, regardless of the storage condition. Salmonella spp. were found in 2/10 RMBDs. This study confirmed that feeding commercial RMBDs might pose a risk to pet health.

Mini-Implant Rejection Rate in Teenage Patients Depending on Insertion Site: A Retrospective Study.

Mini-implants have undeniable advantages in Orthodontics. However, the use of mini-implants shows some limitations and disadvantages related to patient age, the quality of the bone tissue, the characteristics of the oral mucosa, implant site, the state of health of the organism and the quality of oral hygiene. The aim of this paper was to analyze the rejection rate of mini-implants in teenage patients, depending on their insertion site, and examine their stability up to three months after insertion. This retrospective study was conducted on dental charts belonging to patients aged between 12 and 17 years, from Oradea, Romania. The mini-implants were placed for various therapeutic reasons and were inserted in the following sites: buccal maxillary area, the infrazygomatic region, palatal area, buccal mandibular area and lingual area; they had a diameter of 1.6 mm (inter-radicular spaces) and of 2 mm (nonbearing tooth areas), and a length of 6–8 mm (mandible) or 8–10 mm (maxilla). The rejection rate was checked in the first month, second month, third month and after the third month from insertion. A total of 432 patients were included in the study, and they had a total of 573 mini-implants. Most implants were placed in the buccal region of the maxilla (27.7%), and most patients had one mini-implant placed (65.7%). The highest rejection rate was obtained in the first month (15.2%). The rejection rate between genders was similar. The mini-implants from the buccal mandibular region had a significantly higher rate of rejection in the first month (M1) in comparison to the mini-implants from the palatal region (24.4% vs. 8.3%). The mini-implants from the lingual region of the mandible had a significantly higher rate of rejection in the second month (M2) in comparison to the mini-implants from the infrazygomatic or the palatal region (10.5% vs. 0%/0%). Mini-implants are very useful for carrying out various orthodontic treatments, but their stability should be enhanced.

Women during Lactation Reduce Their Physical Activity and Sleep Duration Compared to Pregnancy.

Sleep, mental health and physical activity are fundamental for wellbeing, and some of these factors are interrelated. However, these aspects are not usually considered during pregnancy and lactation, which are particularly vulnerable periods. Therefore, our aims were to conduct a cross sectional study to assess the psychological capital, quality of life, sleep hygiene and physical activity in a cohort of women during pregnancy and lactation periods. Women were recruited from Spanish maternity and lactation non-profit associations and social networks through an online platform with the following inclusion criteria: pregnancy (in any period of gestation) or breastfeeding period (≤6 months postpartum). The cohort was categorized into ≤12 weeks of gestation (n = 32), >12 weeks of gestation (n = 119) and lactation (n = 60). The women self-reported the sociodemographic data, obstetric complications and full breastfeeding or mixed practices. In addition, women responded to the psychological capital instrument, the health survey form, the Pittsburg sleep quality index and the pregnancy physical activity questionnaire. Overall, the groups were similar in sociodemographic variables. Women in the lactation period perceived lower social support compared to the gestation period. No statistically differences were found between groups in the psychological capital nor in the general health survey form. However, the models adjusted by employment and civil and economic status and perceived social support, demonstrated that the sleep duration negatively associated with the lactation period (β = 1.13 ± 0.56; p-Value = 0.016), and the household tasks were associated with this period (β = 2147.3 ± 480.7; p-Value < 0.001). A decrease in physical daily activities were associated with both the end of gestation and the lactation periods. In addition, the decreasing total activity was associated with the lactation period (β = 1683.67 ± 688.05; p-Value = 0.016). In conclusion, during lactation, the poorer sleep and physical activity, together with a lower social support of the woman, may lead to deficient mental health adjustment. Our data suggest that women are at higher risk of vulnerability in lactation compared to the gestation period.

Characterization of the traditional cheese Adghess produced from cow's milk

In Algeria, milk is traditionally transformed into several forms to allow its preservation, particularly fermented products, among which cheese has been the pride of the culinary tradition for a long time. Adghess is a fresh cheese frequently made in the region, especially in rural areas. Adghess is a product poorly known outside its original geographical area. The objective of this study was to characterize Adghess cheese by determining some of its physicochemical and microbiological characteristics. The characterization was preceded by a survey carried out in Oum El Bouaghi with 50 households in order to determine the production diagram of this cheese. The survey was carried out by means of a questionnaire based on random sampling. Ten samples were collected at the level of five farms located in the region and were analyzed for physicochemical attributes such as pH, total dry extract, total lipids as well as, dornic acidity, and microbial population such as total flora, total and fecal coliforms, Salmonella, Clostridium, yeast, and molds. The results obtained showed that the cheese samples analyzed were acidic (pH and an acidity of 4.4 and 38.4°D, respectively). For the total dry extract of Adghess cheese is 334 g kg-1 with a lipid level of 91 g kg-1, the recorded ash content was 3.8g/kg, while sodium chloride was 2.4g/kg. The microbiological results showed a high content of the total flora (7.8×108cfu g-1): Total coliforms were noted to be present in all the analyzed samples, with the absence of fecal coliforms. Unlike molds, yeasts marked their presence (4.6×102cfu g-1). The microbiological findings revealed a high level of total flora (7.8108 cfu g-1): total coliforms were found to be present in all of the examined samples, although fecal coliforms were not found. Yeasts (4.6 102 cfu g-1) left a trace of their existence, unlike molds. The absence of all the pathogenic microorganisms sought (Salmonella, Clostidium, and molds) made the cheese healthier for consumption. Overall, the hygienic quality of the cheese studied was satisfactory. This work constituted the starting point to launch research on this product in order to preserve the know-how on the one hand and achieve the objective of manufacturing it on artisanal, then industrial scales.

Hygienic Quality of Mutton Grills Sold on the Outskirts of the Streets of Korhogo Town

In Korhogo town, there is a proliferation of places selling grilled meats. Also, controlling contamination of meat by pathogenic germs and toxic compounds is a major challenge for actors in the sector. It is in this context that a study was conducted to assess the hygienic quality of mutton grills sold on the outskirts of the streets of Korhogo town. To do this, a survey was conducted among sellers to describe the preparation and storage methods of mutton grills. Then, at points of sale, observations were made on the environment, equipment, raw material, method and workforce in order to assess the hygiene of mutton grills preparation. After that, the microbiological quality of mutton grills was assessed by looking for TMAF, faecal coliforms, S. aureus and Salmonella spp. Finally, the benzo[a]pyrene (BaP) content in mutton grills was estimated through a cooking test. The survey revealed that the majority of mutton grills sellers (60%) cooked the meat over an ember fire and stored the unsold grills at room temperature in basins or baskets. In most of the sale places visited (83.33%), the sellers did not comply with the principle of separating “clean” and “dirty” areas. Microbiological analysis showed that unpackaged mutton grills had better microbiological quality compared to mutton grills packaged in recovery paper, which served as a cement bag. However, the mutton grills overall quality was unsatisfactory in most cases (66.67%). The main microorganisms incriminated in the unsatisfactory quality of mutton grills were S. aureus (53.67%) and faecal coliforms (51.67%). Furthermore, the cooking test indicated that mutton cooked over an ember fire had a BaP content above the recommended maximum limit (2 µg/kg). Considering the results above, the mutton grills sold on the outskirts of the streets of Korhogo town would present a risk of food toxi-infection and poisoning for consumers. These results must be taken into account in order to carry out preventive actions, such as

Hygienic Quality and Conservation of Market Gardening Products Sold in the City of Korhogo (Northern Côte d’Ivoire)

Market gardening is an activity commonly practiced in the city of Korhogo. This study made it possible to take stock of this activity with a view to improving it for the benefit of consumers. A survey was therefore conducted among 100 market gardeners in the Kassirimé, Natio-Kobadara, Koko and Téguérré neighborhoods and 100 vendors at the Sinistré and Belle-Ville markets and at the large market. The results showed that the majority of market gardeners and sellers are women who have not been educated, with more than 10 years of experience. The analysis of production sites through the requirements of the GLOBALGAP standard showed non-compliance rates above 90%. The study on market gardening sites and markets using the ISHIKAWA causality diagram made it possible to identify the risk factors and to propose measures for controlling the dangers. The survey showed that vendors use aeration, ventilation, immersion, drying and sprinkling for the preservation of vegetables. Moreover, market gardeners, like sellers, encounter problems in the practice of this activity. These problems are linked to the lack of supervision, access to agricultural credit and pest’s attacks.
