Consumption Of Chicken Meat Research Articles

Effect of Probiotics on the Length and Weight of Broilers Small Intestine

The increasing need for chicken meat consumption every year makes farmers have to optimize the target of broiler production performance. One solution to maximize production targets is to provide probiotics. Probiotics are live microorganisms that function to increase the effectiveness of the gastrointestinal tract. The media used in making probiotics is prebiotics in the form of milk powder waste with kefir grain starter. In probiotic solutions there are several types of bacteria such as Lactobacillus, Bacillus sp. The purpose of this study was to increase the intestinal length of broiler chickens by probiotic supplementation in finisher phase broiler chickens. The research employed a Group Randomized Design (RAK) comprising 4 treatments and 5 repeats, namely P0 (Without probiotics), P1 (3% probiotics), P2 (5% probiotics) and P3 (7%) implementation of probiotics in broiler chicken drinking water given every afternoon to morning, using One Way ANOVA statistical test parameters with Duncan follow-up tests. Based on the results of P0, P1, P2 and P3 studies that have been carried out, the best probiotic dose research results were obtained at P3 (7% probiotics) with duodenal length worth 50.4 cm, jejenum 86.2 cm and ileum worth 52 cm. The weight of duodenum is worth 29.7 grams, jejenum is worth 30.4 grams and ileum is 30.1 grams.

Analysis of animal-based food consumption of farmer households in Girisubo Sub-district, Gunungkidul Regency

Abstract Food is one the basic necesssities that people must meet. One of the important needs for health is a source of protein. Sources of protein that are often consumed are fish, meat, eggs, and milk. The aim of this study was to identify the reasons that impact the amount of animal-based food consumed by households who engage in farming activities Girisubo Sub-district, Gunungkidul Regency. This study belongs to descriptive research. The research location was determined using the purposive method. The data samples include 100 respondents. The data were analyzed using multiple linear regression. The results showed that the average consumption of animal-based food of farmer households in Girisubo Sub-district, Gunungkidul Regency, was 1.31 kg/month of broiler chicken meat, 1.40 kg/month of broiler chicken eggs, and 1.54 kg/month of tuna. The education level and broiler chicken egg price have a positive effect on the consumption of broiler chicken meat, while cooking oil has a negative effect. The consumption of broiler chicken eggs is influenced by income and cooking oil price. Meanwhile, the factors affecting tuna consumption are income, egg price, tuna price, and cooking oil price. Income elasticity shows that broiler chicken eggs and tuna are categorized as normal goods. The price elasticity explains that tuna consumption is elastic. The cross-price elasticity indicates that broiler chicken eggs are substitute goods for broiler chicken meat and tuna while cooking oil is a complementary goods for broiler chicken meat, broiler chicken eggs, and tuna.

Genomic insights into antimicrobial resistant Salmonella in internationally traded chicken meat: First baseline findings in the United Arab Emirates

Non-typhoidal Salmonella is among the most prevalent foodborne zoonoses, challenging food safety and One Health worldwide. A dearth of knowledge exists regarding non-typhoidal Salmonella prevalence and genomic features within the United Arab Emirates (UAE), one of the top markets in chicken meat consumption worldwide. In this study, Salmonella was detected in 16 out of 254 (6.30 %, 95 % confidence interval: 3.64 %, 10.03 %) samples of imported frozen chicken carcasses sampled from UAE retails. Among the recovered serotypes, S. Minnesota; ST 548 (10/16) emerged as the most prevalent, trailed by S. Heidelberg; ST 15 (4/16), and then S. Kentucky; ST 198, and ST 152 (2/16). Antimicrobial resistance (AMR) was most prevalent against tetracycline (93.7 %), followed by ampicillin (68.7 %), and extended-spectrum cephalosporins (ceftriaxone and cefoxitin) (56.2 %); with 68.7 % (11/16) of the isolates classified as multidrug resistant (MDR). Whole-genome sequencing (WGS) analysis revealed the existence of 14 AMR genes, among which the blaCMY-2, an AmpC cephalosporinases resistance gene, presented in 10 of the 16 isolates. Among the ten out of the eleven MDR Salmonella isolates, both IncC and Col(pHAD28) plasmid incompatibility types were concurrently featured. The range of virulence genes varied from 149 to 165 genes, with an average of 168 genes per isolate. Except for one isolate, all other isolates possessed type III secretion system (TTSS) related genes known to be encoded by the Salmonella pathogenicity island-1 (SPI-1). This study contributes to our global understanding of Salmonella epidemiology, specifically focusing on the Middle East. The insights gained from this study are significant in shaping import risk analyses aimed at mitigating Salmonella exposure risks through globally traded chicken. The research underscores the value of WGS as a crucial tool for substantiating evidence-based food safety hazard assessment.

The impact of nutrition on psycho-affective status in an older Cretan population: a cross-sectional study.

Cognitive and mood status influence both personal and social daily activities, with great impact on life quality, particularly among the elderly population. This cross-sectional study aimed to investigate the psycho-affective status concerning eating habits within an elderly population of the Chania area in Crete, Greece. Cognitive status was assessed in 101 elderly subjects through the Mini-Mental State Examination (MMSE), and mood was evaluated using the Hospital Anxiety and Depression Scale (HADS). Nutritional status was assessed using a validated food frequency questionnaire. Multivariable statistical analysis, after adjustment for age, marital status, education, and comorbidity, highlighted among males a positive association of the MMSE score with vegetable consumption (RR 1.18; 95%CI 1.03‒1.34) and a negative association with potato consumption (RR 0.83; 95%CI 0.72‒0.95). Conversely, among females, no statistically significant association was observed for any food. Further, among males, a protective effect on affective status was identified for chicken meat (RR 0.45; 95%CI 0.27‒0.77), fish (RR 0.41; 95%CI 0.21‒0.82), fruit (RR 0.70; 95%CI 0.52‒0.94), cereals (RR 0.67; 95%CI 0.53‒0.87), and cheese (RR 0.78; 95%CI 0.63‒0.97) consumption. Among females, the adjusted model showed a significant detrimental effect of vegetable consumption (RR 1.33; 95%CI 1.02‒1.73). A predominantly vegetable-based diet-with the notable exception of fruits and legumes-was associated with better cognitive status in males, albeit not in females. A higher intake of fruit, as well as fish, chicken meat, and cheese among males was associated with a better affective status, indicating that adequate protein supply may play a role in maintaining emotional balance.

Assessing concordance between Campylobacter prevalence in broilers and human cases before and during the COVID-19 pandemic in Lower Saxony, Germany, considering fresh chicken meat consumption patterns.

As the most common foodborne disease, number of campylobacteriosis decreased in Germany with the beginning of the COVID-19 pandemic in 2020. As the consumption of fresh chicken meat is a major risk factor for human infection, this study investigated the relationship between Campylobacter contamination levels on chicken carcasses and human cases in Lower Saxony, Germany and observed fresh chicken meat consumption patterns between 2018 and 2021 including the time of the COVID-19 pandemic. Campylobacter levels in broilers and human cases were classified based on the median and descriptively analysed per week using contingency tables. Before the COVID-19 pandemic (2018 and 2019), high Campylobacter contamination levels on neck samples and many human cases were more present, whereas with the beginning of the COVID-19 pandemic (2020 and 2021), low contamination levels on chicken carcasses and few human cases were more present. Lowest concordance between both parameters was shown in 2018 (Cohen's cappa coefficient: 0.37) and 2020 (0.38). The highest concordance was examined in 2021 (0.69). The private consumption of fresh chicken meat in Lower Saxony increased significantly with the beginning of the COVID-19 pandemic in 2020 by 63.9 tonnes compared to 2019 to an average of 453.5 tonnes per week. Public health measures and a reduced number of medical treatments have undoubtedly had an impact on less reported human cases during the COVID-19 pandemic. However, number of human cases remained at a low level in Germany in 2023 while chicken meat consumption increased. Thus, further risk assessments regarding the risk of campyloabcteriosis due to chicken meat consumption should include the country of origin, as the level of contamination of chicken carcasses varies between European countries.

Assessing the environmental sustainability of consumer-centric poultry chain in the UK through life cycle approaches and the household simulation model

Chicken fillets, predominantly encased in disposable plastic packaging, represent a common perishable commodity frequently found in the shopping baskets of British consumers, with an annual slaughter exceeding 1.1 billion chickens. The associated environmental implications are of considerable significance. However, a noticeable gap exists concerning the household-level ramifications of chicken meat consumption, which remains a prominent driver (165 kg CO2eyr−1 per capita) of environmental impacts in the United Kingdom (UK). This study's primary objective is to integrate Life Cycle Assessment (LCA) methodology with insights derived from a spectrum of interventions simulated within the Household Simulation Model (HHSM). The interventions that are simulated are influenced by various consumer behaviours related to the purchase, consumption, storage and disposal of chicken fillets. The overarching aim is to provide a comprehensive understanding of the environmental consequences associated with each intervention.The research encompasses eight distinct household archetypes and the UK average, with a focus on discerning differences in their environmental influence. The introduction of shelf-life extension measures leads to a reduction in the overall environmental impacts (in μPt), with reductions ranging from 1 % to 18 %. Concurrently, waste treatment's environmental burdens can be curtailed by 9 % to 69 % for the UK average. Of the 12 interventions tested, the intervention that combines a one-day extension in the shelf life of open packs and a three-day extension for unopened packs leads to the greatest reduction in environmental impacts, at 18 % for the entire process and 69 % for the waste treatment. This intervention is estimated to yield annual reductions of 130,722 t of CO2 emissions across the entire process and 34,720 t of CO2 emissions from waste treatment, as compared to the default scenario. These findings demonstrate the importance of integrating consumer behaviour, food waste, and packaging considerations within the domain of food LCA research.

Assessment of heavy metals level in chicken with indeterminate analysis in localities of Lahore, Pakistan.

The poultry industry is a significant source of animal protein, vitamins, and minerals, particularly through the consumption of chicken meat. In order to conduct the study, 100 samples of liver, chicken feed, and drinking water were collected in nearby areas of Lahore. The investigation aims to detect the presence of specific heavy metals in the collected samples. For this purpose, atomic absorption spectroscopy (AAS) was used to detect heavy metals after proper preparation of the samples. The experimentally observed data were analyzed through a novel statistical approach known as neutrosophic statistics. It was observed that copper (Cu), zinc (Zn), and cadmium (Cd) were the most prominent metals detected with contamination above the safe limits (for chicken drinking water (Zn = 23.09±13.67 mg/L, Cu = 3.84±3.04 mg/L, Cd = 0.805±0.645 mg/L, Pb = 0.275±0.095 mg/L, As = 0.982±0.978 mg/L), for chicken feed (Zn = 2.705±0.715 mg/kg, Cu = 1.85±0.53 mg/kg, Cd = 3.065±1.185 mg/kg, Pb = 0.215±0.175 mg/kg, As = 0.68±0.22 mg/kg), and chicken's liver (Zn = 3.93±0.66 mg/kg, Cu = 1.2±0.52 mg/kg, Cd = 0.07±0.05 mg/kg, Pb = 0.805±0.775 mg/kg, As = 1.05±0.8 mg/kg)). Similarly, the statistical analysis leads that the findings emphasize the importance of monitoring and mitigating heavy metal contamination in the poultry industry to ensure the safety and quality of poultry products.

Profile of Broiler Chicken Farmers and Supporting Resources in Kepulauan Yapen Regency, Papua Province

Efforts to realize chicken meat consumption have not been achieved. Broiler chicken production in Kepulauan Yapen was about 7,379 and it was not comparable to the human population of 112,676 people. The per capita consumption of chicken meat in Kepulauan Yapen is still far from the national consumption of broiler chicken meat. The research uses descriptive methods with case study techniques. Data taken includes gender, age, education level, business scale, number of family members, farming experience, main job, and marketing channel. Data was obtained from farmers using questionnaires and from various related agencies of the Kepulauan Yapen. The collected data was analyzed using Minitab version 17 to obtain the average and percentage of each data obtained. Results of research showed that the majority of farmers who raise broiler chickens are male (81.82%), aged 15-65 years (100%), have a diploma or above education (45.5%), the scale of business is micro (100%), the number of family members involved in raising broiler chickens is 4 – 6 (54.5%), the farming experience is less than 10 years (100%), the main occupation is others such as trading, hunting (45.45%) and the marketing channel is from farmers directly to consumers.

A comparative analysis of locally sourced feeding systems on chicken body weight gain in Malaysia

The surge in global poultry popularity has led to increased chicken meat consumption. The pandemic-induced rise in imported chicken feed prices has adversely affected the profitability of the chicken meat business. This situation prompted an investigation into the impact of four locally sourced feeding systems on chicken body weight gain, aiming to enhance the profitability of Malaysia’s chicken meat industry. The study, conducted on a Malaysian farm with 200 chickens, analyzed Feeding 1 (Premier Starter Feed (PSF) - Control Feed), Feeding 2 (PSF + SK Gold yellow powder), Feeding 3 (PSF + crude palm kernel oil) and Feeding 4 (PSF + PERFAT Pfi-7 organic acid). Over 14 weeks and 2,800 observations, Engle & Granger’s Vector Autoregression estimation procedure was employed, revealing a positive correlation between chicken age and feeding systems impacting chicken body weight. Feeding 3, incorporating crude palm kernel oil, exhibited the most significant influence on chicken body weight gain, emerging as the optimal and effective choice for improving the chicken meat business. The model’s reliability was affirmed by consistent experimental results, rendering the findings applicable to the commercial market. In conclusion, this research establishes that Feeding 3 is the most efficient, offering valuable insights for commercial applications.

A broad host phage, CP6, for combating multidrug-resistant Campylobacter prevalent in poultry meat

Campylobacter is a major cause of bacterial foodborne diarrhea worldwide. Consumption of raw or undercooked chicken meat contaminated with Campylobacter is the most common causative agent of human infections. Given the high prevalence of contamination in poultry meat and the recent rise of multi-drug-resistant (MDR) Campylobacter strains, an effective intervention method of reducing bird colonization is needed. In this study, the Campylobacter-specific lytic phage CP6 was isolated from chicken feces. Phage CP6 exhibited a broad host range against different MDR Campylobacter isolates (97.4% of strains were infected). Some biological characteristics were observed, such as a good pH (3-9) stability and moderate temperature tolerance (<50 ℃). The complete genome sequence revealed a linear double-stranded DNA (178,350 bp, group II Campylobacter phage) with 27.51% GC content, including 209 predicted open reading frames, among which only 54 were annotated with known functions. Phylogenetic analysis of the phage major capsid protein demonstrated that phage CP6 was closely related to Campylobacter phage CPt10, CP21, CP20, IBB35, and CP220. CP6 phage exerted good antimicrobial effects on MDR Campylobacter in vitro culture and reduced CFUs of the host cells by up to 1-log compared with the control in artificially contaminated chicken breast meat. Our findings suggested the potential of CP6 phage as a promising antimicrobial agent for combating MDR Campylobacter in food processing.

Quantifying health risks from ESBL-producing Escherichia coli in Dutch broiler production chains and potential interventions using compartmental models

Extended-spectrum beta-lactamase (ESBL)-producing Escherichia coli (E. coli) in animals are considered a human health threat, because this type of bacteria can serve as a reservoir of antibiotic resistant genes and act as a continuous threat of the emergence of new resistant bacteria, in addition to the direct effect of making infection untreatable. Although the prevalence of ESBL producing bacteria in broilers was drastically reduced in the Netherlands, chicken meat still has the highest prevalence among meat products. Therefore, further control of the ESBL-producing E. coli in the broiler production chain is important to reduce public health risks. The main objectives of this study were to evaluate the effectiveness of intervention scenarios to reduce the transmission of ESBL-producing E. coli in the broiler production chain and to quantitatively estimate the risk to public health. In this study, we developed two different types of transmission models that described the observed time-related decline in prevalence during a production round: one with time-dependent decline in susceptibility and one with partial immunity to phylogenetic groups. Both models incorporated the environmental contamination effect between production rounds and within flocks. The parameter values, including transmission rate and recovery rate, were estimated by Approximate Bayesian computation (ABC) method using data from a longitudinal study in a Dutch organic broiler farm. We applied the models to the three production stages in the broiler production chain, beginning from the Parent Stock (PS) farms, the hatcheries, and to the broiler farms. In our models, eggs were collected from different parent stock farms and transported to the hatchery and from there to a broiler farm.The size of a flock and the number of farms were adjusted to the Dutch situation. Both models were able to describe the observed dynamics within and between the production stages equally well, with estimated ESBL-producing E. coli prevalence of 8.98% and 11.47% in broilers at slaughter and 0.12% and 0.15% in humans due to chicken consumption. Both models indicated that improving farm management to eliminate the bacteria from the environment was the most effective intervention, making this outcome robust. Although chicken meat consumption is not a major risk factor for human carriage of the bacteria according to our models, reducing the bacteria in the PS and broiler farm environment to at least one percent can further decrease the prevalence in humans.

Antibiogram of Salmonella spp Isolates from Raw Chicken Meat of Kathmandu Valley

Salmonella is one of the pathogenic microbe responsible in food borne diseases. In developing countries like Nepal, Salmonellosis is one of the leading food-borne disease. The present study was conducted with an objective to enumerate coliform and to find the prevalence of Salmonella species in chicken meat along with their antimicrobial susceptible profile. A total of 30 chicken meat samples were collected and examined following the standard techniques and procedures at the Med Micro Lab from January 2020 to April 2020. The study was performed following the conventional methods for the detection of Salmonella spp. Biochemical methods were implied for the detection of isolates and Antibiotic Susceptibility Test were performed by modified Kirby Bauer disc diffusion test [1]. Out of the 30 samples, 12(40%) sample showed positive for Salmonella spp. Salmonella spp 2(16.67%) were found to be resistant to Ciprofloxacin, Chloramphenicol 1 (0.33%), Cotrimoxazole 2(16.66%), Nalidixic acid 7 (58.33%) Ampicillin 3 (25%) and Ceftriaxone (0%). Salmonella was found to be 100% sensitive towards Ceftriaxone. The highest resistance was observed towards Nalidixic acid (58.33%) followed by Ampicillin (25%) and Cotrimoxazole (16.67%). Finally, the result of the study recommended that the use of standardized procedures in slaughtering and handling of chicken meat, provision of training on best practice of handling of meat for handlers and raising the level of awareness of people about the healthy consumption of chicken meat should be increased.

Bacteriology of chicken meat samples from Bharatpur, Chitwan, Nepal

Many food-borne diseases are associated with the consumption of chicken meat and thus are of public health significance worldwide. A cross-sectional study was done to isolate, identify, and characterize bacteria from chicken meat samples of Bharatpur, Chitwan. A total of 102 samples were randomly collected and processed at the Microbiology laboratory of Birendra Multiple Campus, Chitwan for three months (May-July 2016). One gram of each sample was crushed on 9 ml distilled water in a sterile mortar pestle followed by serial dilution and inoculation of 0.1 ml sample into suitable culture media and incubated at 37 оC for 24 hours. Identification of the isolates was done by microscopic examination and biochemical tests and the antimicrobial susceptibility pattern of the isolates was determined by the Kirby Bauer disc diffusion method. Out of 102 meat samples, the growth positivity rate was 94.0% (n = 96/102) on all of the culture media. 26/48 fresh and 44/54 frozen samples gave positive growth with 36 isolates from fresh and 60 isolates from frozen meat samples, with the occurrence of Staphylococcus aureus 26(27.08%), Pseudomonas spp 6(6.25%), Proteus spp 4(4.16%), Escherichia coli 22(22.91%), Salmonella spp 16(16.66%), Citrobacter spp 8(8.33), Acinetobacter spp 8(8.33%), Streptococcus spp 2(2.08%), Shigella spp 4(4.16%) and Vibrio spp 2(2.08%). Cefalexin (92.85%) was the most effective antibiotic against Gram-positive bacteria followed by Amoxicillin (71.42%) and Methicillin (64.28%). The least effective antibiotic was Ampicillin (50%). Similarly, Gentamicin (76.47%) followed by Nalidixic acid (41.47%) were effective against Gram-negative bacteria, while some showed resistance to all three classes of drugs exhibiting MDR.

Chemically Treated Chicken Feather Meal for Fish Feed

The increasing demand and consumption of chicken meat from year to year makes the waste produced also increase, especially chicken feathers. One of the physical waste utilization of chicken feathers is handicrafts that use chicken feathers such as dream catchers. The utilization of chicken feather waste as a feed ingredient is still relatively rare because chicken feathers have crude protein which includes structural protein called keratin. Therefore, it is necessary to process it first so that the keratin in the chicken feather can be degraded properly. The purpose of this review is to provide an overview of the chemical processing of chicken feathers and its application as one of the raw materials that make up fish feed. Based on the results of the review of published articles, chicken feathers contain protein and amino acids that are quite good as fish feed. Chemical processing of chicken feathers is considered more effective and economical because it does not damage the protein in chicken feathers and produces more natural chicken feather flour and can reduce damaged amino acids. The quality of chicken feathers is influenced by chemicals, concentration and length of processing time. Various fish species such as tilapia, catfish and catfish show good growth and survival when fed feed containing chicken feather meal. In other words, chicken feather meal has the potential to be used as an alternative raw material in making fish feed.

Identification of management practices in broiler chicken producers in the Ceibas Arriba village, San Vicente del Caguán, Caquetá

Broiler production is a globally relevant agricultural activity, with chicken meat being one of the most consumed meat products worldwide. In 2018, per capita consumption experienced an increase, led by countries such as Brazil, Israel, the United States and Colombia. At the continental level, the Americas produced around 48.4 million tons of chicken meat, with Brazil as the largest contributor. A significant increase in global chicken meat consumption is expected by 2030, according to FAO. Despite the growth of Colombia's poultry industry, the department of Caquetá has a modest share of national production. San Vicente del Caguán, traditionally focused on livestock, is experiencing growth in poultry production, driven in part by the presence of a veterinary school. In the village of Ceibas Aribas Arriba, about 20 families are engaged in intermittent broiler production. They face challenges such as high feed costs, susceptibility to disease, sudden death and marketing difficulties. Although some families have experienced losses, others have managed to recover with the support of other production systems. Given these challenges, there is a need for research to understand the factors that affect poultry production in this region of San Vicente del Caguán. Poultry farming, despite its influence on the local economy, faces obstacles that limit its development.

Prevalencia y resistencia antimicrobiana de Campylobacter jejuni y Campylobacter coli en pollos parrilleros de una planta frigorífica en Paraguay

Campylobacteriosis is one of the main zoonotic diseases transmitted by food, especially chicken meat and derivatives which represent an important transmission source for humans. This research aimed to verify prevalence and antimicrobial resistance of Campylobacter jejuni and Campylobacter coli in broiler chickens Cobb 500TM obtained from a slaughterhouse in Paraguay. 300 cloacal swabs samples were randomly collected, then subjected to microbiological analysis and subsequent PCR bacterial confirmation. Antimicrobial susceptibility to ciprofloxacin and erythromycin was determined by the E-test®. Campylobacter spp. prevalence was 63.6%, 97.3% corresponding to C. jejuni and 2.6% to C. coli. Resistance to ciprofloxacin was 89.8% for C. jejuni and 100% for C. coli. Resistance to erythromycin was found only in one strain of C. jejuni (0.5%). High resistance to ciprofloxacin and high prevalence of C. jejuni, were confirmed. This research describes public health risk of consumption of chicken meat contaminated with antibiotic-resistant Campylobacter species. The results indicate the need to implement health control measures regarding the antibiotic treatments in poultry production. This research represents the first scientific report that reveals antimicrobial prevalence and resistance of C. jejuni and C. coli in commercial broiler chickens in Paraguay.

Analisis Faktor-Faktor Yang Mempengaruhi Konsumsi Daging Ayam Ras Di Kecamatan Teluk Ambon Kota Ambon

Increasing people's welfare is in line with increasing consumption of broiler meat as a source of animal protein. Improving a person's quality of life has implications for a selective attitude in choosing the quality and quantity of food consumed. This study aims to analyze the factors that influence the consumption of purebred chicken in Teluk Ambon District. The research location was determined purposively, namely deliberately in the market located in Teluk Ambon District, namely Pasar Rumah Tiga and Pasar Wayame. The basis for location considerations is that the people around the market have varied occupational professions and have heterogeneous levels of education. The research sample was drawn using the accidental sampling method, namely taking samples of respondents who are consumers who happen to shop for chicken meat. Respondents were taken as many as 60 people. To analyze the factors that influence the amount of consumption of chicken meat analyzed using multiple linear regression analysis method. The research results show that the price of chicken meat, the price of chicken eggs, the price of fish, the level of education, dependants, tastes, and income together have a significant influence on the amount of consumption of chicken meat. Partially, the variable price of chicken meat, the number of family dependents, income tastes have a significant effect on the amount of chicken meat consumption, while the price of chicken eggs, the price of fish, and the level of education have no significant effect on the amount of chicken meat consumption.

Explainable Machine Learning Models for Identification of Food-Related Lifestyle Factors in Chicken Meat Consumption Case in Northern Greece

A consumer’s decision-making process regarding the purchase of chicken meat is a multifaceted one, influenced by various food-related, personal, and environmental factors that interact with one another. The mediating effect of food lifestyle that bridges the gap between consumer food values and the environment, further shapes consumer behavior towards meat purchase and consumption. This research introduces the concept of Food-Related Lifestyle (FRL) and aims to identify and explain the factors associated with chicken meat consumption in Northern Greece using a machine learning pipeline. To achieve this, the Boruta algorithm and four widely recognized classifiers were employed, achieving a binary classification accuracy of up to 78.26%. The study primarily focuses on determining the items from the FRL tool that carry significant weight in the classification output, thereby providing valuable insights. Additionally, the research aims to interpret the significance of these selected factors in the decision-making process using the SHAP model. Specifically, it turns out that the freshness, safety, and nutritional value of chicken meat are essential considerations for consumers in their eating habits. Additionally, external factors like health crises and price fluctuations can have a significant impact on consumer choices related to chicken meat consumption. The findings contribute to a more nuanced understanding of consumer preferences, enabling the food industry to align its offerings and marketing efforts with consumer needs and desires. Ultimately, this work demonstrates the potential of AI in shaping the future of the food industry and informs strategies for effective decision-making.

Integrasi Pasar Jangka Pendek Ayam Broiler di Indonesia

One of the fast-growing livestock subsectors is the poultry sector. This livestock subsector produces broiler chicken meat as a strategic commodity in addition to beef, milk, and eggs. The level of broiler chicken meat consumption is the highest order, followed by native chicken consumption, then beef. Broiler meat is a rapidly growing strategic commodity. This study uses ECM model analysis to determine the short-term market integration in broiler chickens—time series data on broiler chicken prices at the producer level between January 2015 and December 2020. This analysis's first step is testing broiler chicken meat producer price data stationarity in 28 provinces. Data that are not stationary will be heteroscedastic (have autocorrelation). In addition, time series data that are not stationary can also produce spurious regression, a condition in which two or more variables have a causality relationship, but there is no theory or logic underlying the direct causality relationship between two or more of these variables. According to the findings of this investigation, there is no complete integration. According to the study's findings, the weak flow of information in the market is suspected, so the information transmitted is not perfect. This shows that the broiler meat market in Indonesia leads to imperfect competition. The broiler's construction meat commodity market leads to oligopsony. Government intervention is required to establish broiler meat price control policies with the primary consideration of focusing on the price leader market that will be transmitted in harmony with other regions to make the broiler meat market structure more competitive.

Heavy metal contamination in retailed food in Bangladesh: a dietary public health risk assessment

Introduction Contamination with heavy and toxic metals along the food value chain is a public health concern in Bangladesh. Methods In this study, 608 fish and chicken samples from traditional and modern retail outlets in urban, peri-urban, and rural areas were collected and analyzed for chromium (Cr), cadmium (Cd), and lead (Pb) contamination, using atomic absorption spectrometry method. The daily intake, target hazard quotient and the target carcinogenic risk (for lead only) as a result of fish and chicken consumption was calculated based on mean results, and by Monte Carlo simulation in @Risk with 100,000 iterations (quantitative risk assessment). Results Cr and Cd were detected in 80–86% of both chicken meat and fish samples, while Pb positivity found in chicken meat and fish was 54.9 and 23.3%, respectively. The mean concentration (±SD) of Cr, Cd, and Pb in chicken meat were 0.66 ± 0.93, 0.02 ± 0.03, and 0.09 ± 0.10 mg/kg, respectively; and in fish were 0.49 ± 0.62, 0.02 ± 0.03, and 0.06 ± 0.09 mg/kg, respectively. The estimated daily intakes of Cr, Cd, and Pb from chicken and fish were lower than the maximum tolerable daily intake in all studied areas. In addition, the target carcinogenic risk for Pb in chicken was lower than the negligible range, which indicated the risk of cancer due to exposure to Pb through chicken meat and fish consumption was very low. Discussion The present study concludes that consumption of chicken meat and fish in Bangladesh, currently at very low levels, is unlikely to constitute a major health risk for humans in respect to these metals. However, continuous market surveillance for heavy metals in food stuff is recommended, especially since consumers may increase their meat intake.
