Consumption Of Chicken Meat Research Articles

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.

Anthocyanin based sensory pad for determination of chicken meat spoilage

AbstractProduction and consumption of chicken meat has increased considerably with the increasing world population, and will continue to increase, due to its health benefits and its economic value. Chicken meat is a sensitive food due to its characteristics and microbiological load. Traceability is very important to increase food safety and biosecurity. Freshness indicators are often used to monitor the presence of metabolites produced by microorganisms, mostly functioning through the colour change of the indicator. A developed natural, edible, biodegradable, purple coloured pH sensitive sensory pad was put inside a chicken meat package to observe the chicken meat spoilage with colour change due to pH changes in the meat.

<i>Corrigendum to</i>: Environmental impacts of the Australian poultry industry. 1. Chicken meat production

<sec> Context Steadily increasing consumption of chicken meat (Australia’s most consumed meat protein) has resulted in expanded production. With societal expectations that industries improve sustainability, understanding baseline impacts is vital. </sec> <sec> Aims This study determined carbon footprint (kg CO<sub>2</sub>-e), fossil energy (MJ), fresh water consumption (L), stress (LH<sub>2</sub>O-e) and scarcity (m<sup>3</sup>), and land-occupation (m<sup>2</sup>) impacts for conventional (C) and free-range (FR) production systems, identified hotspots and the implications of changes in production over the past decade, to establish targets for future improvement. </sec> <sec> Methods In the largest study of its kind, attributional life-cycle assessment with data collected for ∼50% of birds processed was used, reporting impacts per kilogram of the typical market mix of chicken products, and boneless chicken. Uncertainty was assessed through Monte Carlo analysis, and results are presented as the means and standard deviation. </sec> <sec> Key results Slightly lower impacts per kilogram of chicken meat product were observed for C production (2.1±0.03kgCO<sub>2</sub>-e, 18.0±0.3MJ, 178.6±22.4L, and 10.2±0.1m<sup>2</sup>) than for FR (2.2±0.03kgCO<sub>2</sub>-e, 18.5±0.3MJ, 189.6±24.6L, and 10.6±0.1m<sup>2</sup>). Feed production was the major hotspot, followed by grow-out and meat processing. Land use (LU) and direct land use-change (dLUC) impacts associated with imported soymeal added 1.7±0.3 and 1.8±0.3kgCO<sub>2</sub>-e to C and FR respectively. FR carbon footprint and land occupation were significantly (<i>P</i><0.05) higher. Since 2010, fossil energy, arable land, and greenhouse-gas emissions have declined. One countertrend was LU and dLUC emissions, which increased due to changed soy imports, resulting in a slightly higher C carbon footprint. </sec> <sec> Conclusions Multi-indicator analysis is fundamental to understanding, communicating, and improving performance, and distinguishing between short-term fluctuations and long-term trends. Since 2010, feed-production impacts have increased (due to imported soymeal in poultry diets), indicating that alternative feed protein sources are a priority. Efficiency improvements reduced per-kilogram impacts across other indicators, demonstrating a positive trend in producing more food from fewer inputs. </sec> <sec> Implications Australian chicken meat is a low-impact animal protein. Future improvements require alternative feed proteins, technology adoption and practice change to maintain or reduce impacts as production expands alongside consumer demand. </sec>

Human health risk assessment of edible body parts of chicken through heavy metals and trace elements quantitative analysis.

Food safety and security have now been regarded as a significant emerging area within the food supply chain leading to scientific and public health concerns in the global world. The poultry sector is a substantial threat to heavy metal intoxication for Bangladeshi people due to contaminated drinking water and feed sources, as well as the poultry sector's surrounding environment and soil. This study was carried out to ascertain the residual concentrations of heavy metals (Pb, Cd) and trace elements (Cr, Fe, Cu, and Zn) in various edible chicken body parts (breast, liver, gizzard, heart, kidney, and brain) to observe the quality of the consumed chickens and to assess public health risk. Atomic absorption spectrometry (AAS) was used to check the content of toxic heavy metals and trace elements in 108 samples of 18 broiler chickens collected from six different locations of Dhaka North City Corporation markets in Bangladesh. The measured concentrations (mg/kg fresh weight) ranged from 0.33±0.2 to 4.6±0.4, 0.004±0.0 to 0.125±0.2, 0.006±0.0 to 0.94±0.4, 4.05±4.2 to 92.31±48.8, 0.67±0.006 to 4.15±2.7, and 4.45±0.62 to 23.75±4.3, for Pb, Cd, Cr, Fe, Cu, and Zn respectively. Except for Pb and Cu most of the investigated heavy metals and trace element levels in chickens were lower than the maximum allowable concentration (MAC) set by FAO/WHO and other regulatory agencies., The estimated level of Pb was nearly six times higher in the chicken brain. The estimated daily intake (EDI) values for all the studied metals were below the preliminary tolerated daily intake (PTDI). The target hazard quotient (THQ) values of the broiler chicken meat samples varied for adults and children, and the range was found to be 0.037-0.073 for Pb, 0.007-0.01 for Cd, 0.0-0.08 for Cr, 0.002-0.004 for Fe, for 0.00-0.002 Cu, and 0.004-0.008 for Zn, not exceeding the maximum level of 1 according to USEPA. The calculated THQ and total target hazard quotient (TTHQ) values were measured at less than one, suggesting that the consumption of chicken meat has no carcinogenic danger to its consumers. The Target carcinogenic risks (TCRs) of Pb, Cd, Cr, and Cu were within acceptable limits. The TCR values for children were, to some extent, higher than that of adults, which proposes that regular monitoring of both harmful and essential elements in chicken samples is necessary to determine whether or not any possible health risk to consumers exists. In terms of health, this study demonstrated that consumers are chronically exposed to elemental contamination with carcinogenic and non-carcinogenic effects.

ANALYSIS OF SUPPLY AND DEMAND OF BROILER CHICKEN MEAT IN BALI PROVINCE

This study aims to analyze factors such as broiler chicken population, DOC prices, feed prices and drug prices on boiler chicken meat supply, and population, per capita income, boiler chicken meat prices, tourist visits and religious holidays to demand boiler chicken meat in Bali Province. The research method used is multiple linear regression analysis with the help of the SPSS program and trend analysis. Used 2 dependent variables and 9 independent variables. The data used in this study are primary data obtained from interviews with 100 respondents, while secondary data is obtained from annual data from 2009 to 2019. The results of the study concluded that the broiler chicken population, DOC prices, feed prices and drug prices had no effect on the supply of boiler chicken meat at the 95% confidence level and R2 of 0.641. This is because most breeders have partnerships with companies. Meanwhile, partially the demand for boiler chicken meat is determined by the population with a coefficient of 0.045 at 95% confidence. This shows that the increase in population is directly proportional to the consumption of broiler chicken meat. While other variables do not affect the demand for broiler chicken in Bali Province.

Estimando a produção de carne de frango em países líderes para os anos 2019-2025

ABSTRACT: The study predicted chicken meat production in 2019-2025 period for the leading chicken-producing countries with the help of the 1961-2018 Food and Agriculture Organization (FAO) data since chicken meat consumption is so high worldwide. The USA ranks the first place while Brazil and China take second and third places, respectively. The analysis of the pioneer chicken meat-producing countries indicates that while the portion of the USA in world production decreases, the share, particularly Brazil and China, will approach that of the USA. World chicken meat production, which was 7.56 million tons in 1961, will increase to 139.19 million tons in 2025, and this production per capita is predicted to increase to 17.0 kg in 2025 from 2.4, 5.35, 9.80, and 15.0 kg in 1961, 1981, 2001, and 2018, respectively. Indonesia, Russia, Brazil, Japan, and India will run the highest increases in production. However, the share of countries in chicken meat production will decrease from 61% to 60% in 2019-2025 compared to the 2012-2018 periods. This condition showed that apart from some leading countries, the production will keep a rapid increase in production. The increase in chicken meat production and chicken meat import worldwide will improve human nutrition, especially in developing and underdeveloped countries. Countries that run cost advantages and high-quality life standards in line with technological innovations produce processed chicken products, strengthen animal health, hygiene, and transportation standards, and attach importance to advertising activities that increase consumer demand will be more advantageous in this market.

COMPARISON AND RISK ASSESSMENT OF TRACE METAL CONTENT IN FACTORY-FARMED BROILER AND FREE-RANGE CHICKEN MEAT SOLD IN LAGUNA, PHILIPPINES

Chicken meat consumption remains high in the Philippines, and consequently, annual chicken production has risen steadily over the years. Although most of the chicken meat available in the market are sourced from factory farms, there has been growing popularity of free-range chicken production, largely driven by its perceived health benefits and sanitation concerns in factory farms, among others. In this work, we aimed at comparing the trace metal (copper, iron, lead, manganese, and zinc) content of free-range and factory-farmed broiler chicken meat that are being sold in Laguna, Philippines. The samples were subjected to acid digestion and analysis was done using atomic absorption spectrometry. Results showed an average concentration between 0.17 – 0.24 mg/kg, 2.22 – 2.34 mg/kg, 0.12 – 0.15 mg/kg, 0.95 – 1.32 mg/kg, and 1.81 – 1.96 mg/kg for copper, iron, lead, manganese, and zinc, respectively. Statistical analysis using one-way ANOVA and Tukey multiple comparison test (p < 0.05) showed no significant differences in the trace metal content of free-range and factory-farmed chicken meats, suggesting that in terms of the levels of these trace metals, not much differentiates the two varieties. Analysis of the health hazards, reported as target hazard quotient (THQ) and hazardous index (HI), associated with the consumption of the said chicken breast meat indicated no potential health risks.

Impact of COVID-19 Lockdown on Livestock and Poultry Sectors: Veterinary Students Perception and Suggestions

The study was undertaken to know perception of veterinary students on impact of COVID-19 lockdown on livestock and poultry sectors and suggestions to manage the lockdown impact. Data were collected through google form from 73 veterinary undergraduate students on July 2021. The data was analysed by descriptive statistics, Rank Based Quotient (RBQ) and results were interpreted. Our results revealed that veterinary students strongly agreed with increased prices for concentrate feed and limited supply (50.70%), limited availability of veterinary doctors for private practices (39.70%), declined livestock sales owing to livestock transportation constraints (41.10%) and declined demand for meat/livestock due to consumer unreadiness (28.80%) toward the livestock sectors. Further, the study reported that veterinary students had greater perception on price drop of eggs and broiler chicken during lockdown's initial period (47.90%), rise in consumption of country chicken meat and eggs (61.60%) and farm labour shortages (47.90%) in the poultry sector. These participants suggested, expansion of milk collection centres; and sell milk and meat via a mobile van (RBQ 47.06); give COVID-19 vaccination priority to farm labour; employ family labour for farm maintenance (RBQ 36.76); and promote COVID-19 measures through prominent local leaders (RBQ 35.29) to manage COVID-19 impact on livestock.

Growth, innovation, and policy for chicken in Latin America 1961–2019

SummaryMotivationLatin America has witnessed massive increases in production and consumption of chicken meat over the last 60 years and well beyond its share of the developing world's population. Chicken is now a major source of livestock protein in regional diets; leads livestock production in 25 out of the region's 33 countries; production, slaughtering, and sales provide millions of jobs.PurposeTo analyse growth rates for chicken meat in Latin America, why they have differed, how the role of innovation and development policies contributed to bringing about this growth, in turn leading to the patterns of governance of these activities today.Methods and approachThis study used a modified value chain framework along with FAO statistics, national data, published and unpublished studies to analyse macro‐level developments and their linkages to shifts in the organization of activities in the value chain for chicken from pre‐production through to consumption and trade from past to present.FindingsDifferent natural resource endowments, demographics, and dietary preferences combined with frequent innovations and an array of policy measures led to a spectacular surge in output and productivity, lower costs, and facilitated a steady rise in consumption. As part of that growth, these activities became increasingly concentrated in Brazil, Mexico, and Peru and within those countries in a few very large firms. Their operations expanded in the value chain beyond the farm gate, across the region, and in some cases around the world.Policy implicationsThis paper has implications for greater transparency in grower contracts, better working conditions for slaughterhouse workers and bird catchers, more environmentally and bird‐friendly chicken production, accelerated adoption of practices as per Principles for Responsible Investment in Agriculture and Food Systems in the value chain for broilers in Latin America and the Caribbean, and improved enforcement of laws and regulations governing the technical and financial operations of value chains for chicken, along with renewed collaboration among government authorities to that effect.

Detection of Toxocara species larvae in four Iranian free-range broiler farms

BackgroundThe epidemiology of Toxocara canis and Toxocara cati in food animals, associated products, and their zoonotic potential are poorly understood. A cross sectional study was designed to determine the prevalence of Toxocara spp. larvae from free-range broiler chickens in traditional farms using conventional techniques and molecular method. Eight-hundred tissue samples including liver, gizzard, lungs and heart were collected from 200 chickens belonging to different regions of Zanjan Province, Iran and were processed by conventional and molecular methods.ResultsOut of 800 chicken tissues, 49 samples (6.1%) were positive for nematode larvae. Polymerase chain reaction was performed to identify species-specific of Toxocara larvae. The findings showed that 10.5% (21 out of 200) chickens were infected with Toxocara species, so that 57.1% (12 out of 21) of the samples were positive for Toxocara canis and 42.9% (9 out of 21) of the samples were positive for Toxocara cati.ConclusionConsidering the significant contamination/infection of free-range broiler chickens with Toxocara larvae, the consumption of chicken meat and viscera, especially liver and gizzards, can play an important role in the transmission of infection to humans. Prevention and control measures focused on regular deworming of dogs and cats, increasing public awareness of Toxocara infection are recommended.

Pengaruh Konsentrasi HCl Pada Proses Exfoliasi Graphene Oxide/Reduce Graphene Oxide (GO/rGO) Dari Karbon Bulu Ayam

<p class="AbstractText"><span lang="EN-AU">An increase in the consumption of chicken meat may have an impact on the waste of chicken feathers. Several efforts have been made to treat chicken feather waste, which is difficult to decompose and can pollute the environment. Chicken feathers are biomass with a high keratin content that has the potential to be used as a carbon material. In this study, chicken feathers were used in the chemical exfoliation method to produce reduced Graphene Oxide (rGO) material.

The exfoliation procedure was carried out with varying concentrations of HCl (0, 0.5, 1, 1.5, and 2 M). The X-ray diffraction spectra revealed that the sample had a rGO type carbon phase, with the crystal size decreasing as the HCl concentration increased. The presence of functional groups C-O, C=C, and C-OH identified as GO/rGO was revealed by FTIR spectra. The HCl exfoliation process reduced the sample's conductivity and capacitance, with the highest values obtained in aquadest sample (GO-0 M), about 10<sup>-5</sup> S/m and 10<sup>-7</sup> F/m<sup>2</sup>.</span></p>

The animal welfare cost of meat: evidence from a survey of hypothetical scenarios among Belgian consumers

ABSTRACT A survey in Belgium with hypothetical scenarios concerning willingness to pay to avoid the experiences of farm animals is used to estimate the animal welfare costs of meat production. Most participants indicate that farm animals have lives not worth living. The median estimate of the animal welfare cost of chicken meat is 10 euro/kg, whereas its mean estimate is several orders of magnitude higher. The animal welfare costs of meat are likely much larger than the consumer utility of meat consumption, the consumer willingness to pay for higher animal welfare meat and the climate/environmental costs of meat. A demand shift from beef to chicken meat due to misaligned consumer concerns for animal welfare or a carbon tax on meat, could possibly increase animal welfare costs and decrease the non-anthropocentric social welfare function. Consumers could prioritize lowering chicken meat consumption and governments could implement a flat tax on meat.

Molecular detection of Toxoplasma gondii in Tunisian free-range chicken meat and their offal.

Free-range chickens are infected by Toxoplasma gondii (T. gondii) mainly when they pick-up their food from the ground. The present study was performed to estimate the molecular prevalence of T. gondii in free-range chicken meat (breast and thigh muscles) and their offal (heart and gizzard). The molecular characterization and the phylogeny of T. gondii amplicons were also investigated. Two PCRs were compared, the first targeting B1 gene and a nested PCR targeting the internal transcribed spacer ITS-1 gene. Among the 60 tested birds, 47 free-range chickens had at least one positive PCR, i.e., a prevalence of 78.3% (95% CI: 67.9-88.7%). The prevalence of T. gondii infection in muscles and organs analyzed by specific PCR targeting B1 gene (43.3%; 95% CI: 37-49.6%) was significantly higher than those analyzed for ITS-1 gene detection (15%; 95%CI: 10.4-19.5%) (p < 0.001). Heart samples had the highest T. gondii infection prevalence, as well as targeting either B1 gene (48.3%; 95% CI: 35.6-60.9%) or ITS-1 gene (21.6%; 95%CI: 11.2-32%). The present study showed that the consumption of undercooked free-range chicken meat represents a high risk for seronegative pregnant women. Our phylogenetic analysis revealed homology with wild and domestic birds and domestic mammals and a large geographic distribution.

Willingness to Pay for Safe Chicken Meat in Bangladesh: A Contingent Valuation Approach

The poultry meat industry is primarily dominated by broilers, and conventional broiler meat is claimed to be malicious to human health and environment since it is produced using hazardous feeds and other dietary supplements. This study aimed to evaluate consumers’ willingness to pay (WTP) for safe broiler chicken meat following a contingent valuation model (CVM). Also, consumers’ consumption and different types of perceptions on safe broiler meat were assessed from the data collected among 300 consumers in Bangladesh. Consumers’ health and environmental perception of safe broiler meat are found to be high, indicating that they are more concerned about these attributes in the case of consuming broiler meat. The results reveal that conventional broiler meat losses its appeal to consumers after a certain income level and is mainly consumed by lower- and middle-income groups. This study divulges a unanimous demand for safe broiler meat among the consumers who intend to consume about 36% higher than their present consumption level if the availability was ensured in their local market. The average WTP premium for safe broiler meat is estimated to be about BDT 39.87 per kg. The consumers’ WTP is positively influenced by their education, income level, the current consumption of broiler chicken meat, health perception, and taste and nutrition perception. This study recommends meat producers, entrepreneurs, and farmers adjust their production and marketing plans by incorporating suitable quality control procedures to meet the unfilled consumer demand for safer broiler meat. Besides, slow-growing safer broiler chicken needs to be introduced to improve meat’s taste and nutritional aspects.

Pulsed Light Application for Campylobacter Control on Poultry Meat and Its Effect on Colour and Volatile Profile.

Campylobacter on poultry meat needs to be controlled to reduce the risk of infection caused by the consumption of chicken meat. Pulsed light (PL) application on poultry meat was studied to control Campylobacter spp. The effect of this technology was evaluated regarding poultry meat colour and volatile compound changes. Two breast sample groups were prepared: inoculated with Campylobacter (107 bacteria of Campylobacter jejuni strains) and not inoculated. Samples were submitted to PL, five pulses/s of 300 ms, 1 Hz, and 1 J/cm2 in the apparatus, PL Tecum unit (Claranor). A response surface experimental design was applied regarding the factors of voltage (1828 to 3000 W) and distance to the source UV lamp (2.6 to 5.4 cm). The binomial factorial treatment (voltage and distance) with PL induced different energy doses (fluence J/cm2) received by samples, 2.82 to 9.67 J/cm2. Poultry meat pulsed light treated had a significant decrease of Enterobacteriaceae counts. The treatments applied were unable to reduce 1 log Campylobacter cfu/g of poultry meat. The poultry meat PL treated became slightly light, redder, and yellower than those not treated. PL can decrease the proportion of aldehydes on total volatiles in meat, particularly on those associated with chicken-like, chicken skin-like, and sweet odour notes in fresh poultry meat. Further studies of PL with higher energy doses will be necessary to confirm if there are Campylobacter reductions and about poultry meat treated under storage to evaluate if volatile compounds can affect the flavour of PL-treated meat samples.

Genotypic and phenotypic quantitative microbial risk assessment model of human salmonellosis related to the consumption of chicken meat in the central region of Mexico

Chicken meat is often associated withSalmonella entericacontamination worldwide. This study proposes a risk assessment model for human salmonellosis linked to the domestic consumption of chicken meat in the central region of Mexico, incorporating genotypic and phenotypic data. SixS. entericagroups were used, considering the presence of specific virulence genes and multidrug resistance (MDR). Sixteen exposure scenarios were established considering retail point (RP1 = fresh market/butcher shop; RP2 = mini-super/supermarket), transportation, home storage, cooking, and cross-contamination. The model predicted a mean annual salmonellosis cases of 66,754 due to chicken consumption (CI95% 10775–231606). The mean probability of illness (Pill) among the exposure scenarios ranged from 2.5 × 10-9 to 3.7 × 10-6, 7.7 × 10-8 to 1.1 × 10-4, and 6.7 × 10-4 to 7.8 × 10-2 for low, moderate, and high virulence groups. Exposure scenarios with the highest Pill were not responsible for most cases due to their low frequency of occurrence. The high virulence/ MDR group was responsible for most cases (66.5 %), despite the low S. enterica prevalence (RP1 0.5 % and RP2 5.0 %). The years lost due to disability (YLD) value for MDR was 2.6 × higher than for non-MDR. Spearman rank showed that the inputs with higher influence on the variability of salmonellosis depended on the type of exposure scenario. For example, the cooking temperature and time had the most significant influence in the scenarios where S. enterica can survive after cooking.Including the microbial genotypic and phenotypic characteristics in risk assessment modeling highlights the importance of focusing on high-virulent and MDR strains, which are not the most frequent but represent the highest public health risk.

ESBL producing &lt;em&gt;Escherichia coli&lt;/em&gt; prevalence in chicken stools in selected broiler farms in Galle district

Introduction: Most of the animals reared for food are reservoirs for Extended Spectrum Beta-lactamase (ESBL) producing coliforms. ESBL producing Escherichia coli (E. coli) in chicken meat are increasing worldwide. Since the consumption of chicken in meals is higher compared to other livestock in Sri Lanka, there is a threat to transmit these organisms to humans via food. The aim of this study was to determine the ESBL producing E. coli prevalence in chicken stools and the presence of antibacterial substances in chicken feed and water in selected broiler farms in Galle district Methods: Eighty stool samples were collected from selected broiler farms in Galle district. Isolates were confirmed as E. coli on the lactose fermentation, colony morphology, Gram staining and biochemical tests. ESBL production was detected according to the CLSI double disc diffusion method. Ready to serve chicken feed and water samples were collected and tested against two types of E. coli control cultures using agar well diffusion method to detect the effects of any antibacterial substances. Results: Eighty-six different types of E. coli were isolated from 80 chicken stool samples. There were no ESBL producers among all isolated E coli. There was no antibacterial activity demonstrated in food or water served for chicken except for in one farm. The percentage distribution of fecal microbial flora as well as their density was altered in the farm where antibiotics were used in chicken feed. Conclusions: No ESBL producing E. coli were detected in chicken stool in the selected broiler farms of Galle district indicating the minimum risk of transmission of ESBLs to the human via consumption of chicken meat.
