Effect of precipitation methods on physicochemical properties of keratin films produced from chicken feather waste

AbstractEngineering keratin plastics from chicken feather wastes is highly attractive from an environmental prospect but challenging due to the influence of extraction routes on the macromolecular keratin features. In this study, the effect of precipitation methods on desired properties of biodegradable keratin films was investigated. Keratin was extracted from an industrial chicken feather waste by sulfitolysis, and further recovered using hydrochloric acid (KHA), citric acid (KCA), sodium chloride (KSC), and acetone (KAT) as precipitating agents. Keratin films containing glycerol at 25 wt% were produced by compression molding. All keratin films were nearly colorless and highly transparent to visible light while exhibiting good UV barrier properties. The KAT and KSC films showed greater ductility (εbreak > 50%) compared with KHA and KCA, which was correlated with broader molecular weight distributions and less crosslinking in the former keratins. Importantly, disulfide bonds created in the processing led to keratin films with low water solubility. Larger surface hydrophobicity was attained from keratin recovered by organic solvent precipitation (KAT). These results advance the understanding of precipitating agents as physicochemical property modifiers of biodegradable keratin films for food packaging and other applications.

Dynamics of microbial functional guilds involved in the humification process during aerobic composting of chicken manure on an industrial scale.

Proper composting treatment of poultry manure waste is recommended before its use as a fertilizer. This involves many bioprocesses driven by microorganisms. Therefore, it is important to understand microbial mechanisms behind these bioprocesses in manure composting systems. Many efforts have been made to study the microbial community structure and diversity in these systems using high-throughput sequencing techniques. However, the dynamics of microbial interaction and functionality, especially for key microbial functional guilds, are not yet fully understood. To address these knowledge gaps, we collected samples from a 150-day industrial chicken manure composting system and performed the microbial network analysis based on the sequencing data. We found that the family Bacillaceae and genus Bacillus might play important roles in organic matter biodegradation at the mesophilic/thermophilic phases. Genera Virgibacillus, Gracilibacillus, Nocardiopsis, Novibacillus, and Bacillaceae_BM62 were identified as the key ones for humic acid synthesis at the mature phases. These findings improve our understanding about the fundamental mechanisms behind manure composting and can aid the development of microbial agents to promote manure composting performance.

МОНИТОРИНГ УСТОЙЧИВОСТИ ПРОМЫШЛЕННОГО КУРОВОДСТВА АЛМАТИНСКОЙ ОБЛАСТИ КАЗАХСТАНА К САЛЬМОНЕЛЛЁЗУ

Salmonellosis is a common digestive infection of the food chain, so it is important to provide bio-logical protection of poultry farms to exclude economic losses and prevent horizontal transfer of Salmo-nella bacteria through chicken products (eggs, meat) to humans. The aim of the study was to conduct comprehensive monitoring and study the resistance of industrial chicken farming in some poultry farms in Almaty region of Kazakhstan to bacteria of the genus Salmonella. The research methodology was based on weekly sampling from the environment of poultry farms in Almaty region of Kazakhstan and determination of the presence of bacteria of Salmonella genus in the selected samples by culture and biochemical methods. Samples from the technological facilities of poultry farms were taken from the entire calendar year. A total of 5672 samples were collected for testing, including 537 samples of litter, 3838 samples of flushes, 1024 samples of eggs, 181 samples of dust, 43 samples of straw, 49 samples of transport crates, litter paper and cardboard used for transport crates. Of the 5672 samples tested, the presence of Salmonella bacteria was recorded in 24 samples (0.5% of all samples tested). The results of these studies showed that detection of Salmonella bacteria in the tested samples is an effective method of biosecurity management for poultry farmers and allows them to quickly find sanitary and zoohygienic solutions in order to prevent the threat of Salmonella bacteria in chicken farms. Therefore, the efforts of poultry farms to reduce the transmission of Salmonella bacteria through chicken products should be realized on the scale of Kazakhstan.

Renewable Energy from Livestock Waste Valorization: Amyloid-Based Feather Keratin Fuel Cells.

Increasing carbon emissions have accelerated climate change, resulting in devastating effects that are now tangible on an everyday basis. This is mirrored by a projected increase in global energy demand of approximately 50% within a single generation, urging a shift from fossil-fuel-derived materials toward greener materials and more sustainable manufacturing processes. Biobased industrial byproducts, such as side streams from the food industry, are attractive alternatives with strong potential for valorization due to their large volume, low cost, renewability, biodegradability, and intrinsic material properties. Here, we demonstrate the reutilization of industrial chicken feather waste into proton-conductive membranes for fuel cells, protonic transistors, and water-splitting devices. Keratin was isolated from chicken feathers via a fast and economical process, converted into amyloid fibrils through heat treatment, and further processed into membranes with an imparted proton conductivity of 6.3 mS cm-1 using a simple oxidative method. The functionality of the membranes is demonstrated by assembling them into a hydrogen fuel cell capable of generating 25 mW cm-2 of power density to operate various types of devices using hydrogen and air as fuel. Additionally, these membranes were used to generate hydrogen through water splitting and in protonic field-effect transistors as thin-film modulators of protonic conductivity via the electrostatic gating effect. We believe that by converting industrial waste into renewable energy materials at low cost and high scalability, our green manufacturing process can contribute to a fully circular economy with a neutral carbon footprint.

Performance of IC Engines Using Chicken Waste as Biofuel, CNT and MnO Nano-Biofuels and Diesel Fuel: A Comparation Study

Biofuel production and its properties improvisation are the wide areas of research in internal combustion (IC) engines. This research derived biofuel from industrial chicken waste. Nanofuels were produced in this study by adding 40 nm-sized nanoparticles of carbon nanotube (CNT) and manganese oxide (MnO) with a variation of 100 to 200 ppm to the derived oil. Four fuel blends (biofuel (B), B with CNT, B with MnO, and B with CNT+MnO) were compared to the performance of diesel fuel in a 3.5 kW CI engine. The combustion process (peak pressure and heat release), brake thermal efficiency (BTE), and exhaust emissions (CO, HC, NOx, and CO2) were used as parameters to evaluate the fuel’s performance. The result revealed that nanofuel outperformed both diesel fuel and biofuel. The addition of 200 ppm CNT in biofuel enhanced the fuel properties, resulting in higher BTE by 28% and 9.7% compared to diesel fuel and biofuel. The CNT-biofuel also generated fewer emissions compared to diesel fuel by 26%, 9.4%, and 25% for NOx, HC, and CO gases respectively.

Molecular detection of Neospora caninum in chicken meat and eggs in Iran

Neospora caninum is an obligatory intracellular protozoan parasite, phylum Apicomplexa. Canids are definitive hosts and different animals can be intermediate hosts. Neospora DNA has been also detected in humans, recently. This study aimed to understand the infection rate of N. caninum in chicken meat because consumption of raw and undercooked meat can be the main risk factor for canine neosporosis. Investigation of Neospora vertical transmission to the eggs is also important. One hundred chicken legs, and fifty eggs from free-range chickens, and fifty eggs from industrial chickens were collected from different stores in Semnan city, Iran. Deoxyribonucleic acid (DNA) of samples was extracted, and the Nested-PCR (polymerase chain reaction) on Neospora internal transcribed spacer (ITS-1) gene was performed. Neospora caninum DNA was detected in eight out of one hundred (8%) chicken legs, and no eggs were infected. These results revealed that N. caninum infection in chicken meat for the first time in Iran. For the investigation of Neospora vertical transmission to eggs, more studies will be necessary. Indoor carnivores should be fed, and humans should be consumed well-cooked chicken meat to prevent infection.

Evaluation of the sanitary and hygienic characteristics of chicken meat and semi-finished products

This article presents research on sanitary and bacteriological evaluation of the quality of semi-finished chicken meat and whole chicken carcasses sold in Kostanay. The quality of products was evaluated by organoleptic, biochemical and bacteriological indicators. A total of 32 samples were analyzed, including whole chicken carcasses of domestic poultry and industrial chicken carcasses, as well as semi-finished chicken products (shank, thigh, wings on a substrate). During organoleptic and biochemical analysis of the quality of the samples 5 samples did not meet the requirements of normative documents. Sanitary and bacteriological examination showed excess of total microbial contamination. In a sample of imported semi-finished products the presence of Bacteroidetes was detected. Salmonella and L. monocytogenes bacteria were identified in two samples of domestic chicken. In order to facilitate faster identification of pathogens in food, chromogenic selective media were used, which have a high sensitivity and facilitate their identification. Due to the presence of markers of specific enzymatic activity, the colonies of the bacteria in question are stained with a characteristic colour and the growth of extraneous microflora is inhibited. The use of modern nutrient media saves time for routine laboratory tests.

Antimicrobial Resistance in Poultry Farming: A Look Back at Environmental Escherichia coli Isolated from Poultry Farms during the Growing and Resting Periods.

During the production cycle of poultry farms, pathogens may remain in the next cycle of rearing young chickens. This study was conducted at three industrial chicken farms (A, B, and C) in central Thailand. Results showed that the percentages of E. coli during the resting period in farms A, B, and C were 28.6, 53.8, and 7.8, respectively, and those during the growing period were 45, 68.8, and 75. The most common resistant patterns during the resting period in all farms were AML-AMP-SXT and AML-AMP-DO-SXT, and those during the growing period were AML-AMP and AML-AMP-SXT. The locations of blaTEM-positive E. coli isolates from the inside houses (inside buildings) of all farms included cloacal swabs, floors, water nipples, pan feeders, and husks, whereas that from the outside environment included boots, wastewater, soil, and water from cooling pads and tanks. Our results indicate that the percentage of antimicrobial resistance (AMR) and its pattern depend on the husbandry period and the strictness of biosecurity. Moreover, our findings derived from samples gathered from broiler farms between 2013 and 2015 align with those of the current studies, highlighting persistent trends in E. coli resistance to various antimicrobial agents. Therefore, enhancing biosecurity measures throughout both the resting and growing periods is crucial, with a specific focus on managing raw materials, bedding, breeding equipment, and staff hygiene to reduce the transmission of antimicrobial resistance in poultry farms.

Effects of supplementation of pomegranate processing by-products and waste cooking oils as alternative feed resources in broiler nutrition.

Agricultural residues can be used as alternative feed sources in industrial chicken production. The impacts of different levels of pomegranate peel and waste cooking oil as an agricultural residue on broilers' nutrition were investigated. Results showed that the replacement of 8% pomegranate peel in diets decreased the growth performance of broilers. Supplementing 8% pomegranate peel in diets reduced apparent nutrient digestibility. The highest level of waste oil inclusion in broiler diets indicated negative impacts on apparent zmetabolizable energy and crude fat apparent nutrients digestibility. Broilers fed the diet containing 4% pomegranate peel had a higher Lactobacillus population. The results showed that the Lactobacillus population was lower in broilers fed 8% pomegranate peel powder and 4% waste oil in diets. The inclusion of 8% pomegranate peel powder in diets showed lower villus height and crypt depth in the duodenum, jejunum, and ileum. The inclusion of 4% pomegranate peel decreased the peroxide value (PV) of meat. Dietary inclusion of 4% waste oil raised the PV of meat. Alpha-tocopherol supplementation decreased the PV of meat. Finally, the results provide information that 4% of pomegranate peel and 4% waste oil could be used as an alternative feed ingredient in broiler diets without adverse effects.

Comparison of Antimicrobial Susceptibility Profiles of Thermotolerant Campylobacter spp. Isolated from Human and Poultry Samples in Georgia (Caucasus).

Antimicrobial resistance remains a public health concern globally. This study presents antimicrobial resistance by microdilution and genetic diversity by the whole-genome sequencing of Campylobacter spp. from human and poultry samples isolated in Georgia in 2020/2021. The major species in poultry samples was C. coli, while C. jejuni was preferentially isolated from human samples. Resistance against tetracycline was highest (100%) in C. coli from industrial chicken and lowest in C. jejuni from clinical isolates (36%), while resistance against ciprofloxacin varied from 80% in C. jejuni from backyard chicken to 100% in C. jejuni and C. coli from industrial chicken. The point mutations in gyrA (T86I) and tet (O) genes were detected as resistance determinants for (fluoro-)quinolone or tetracycline resistance, respectively. Ertapenem resistance is still enigmatic. All isolates displayed sensitivity towards erythromycin, gentamicin and chloramphenicol. Multi-resistance was more frequently observed in C. coli than in C. jejuni, irrespective of the isolation matrix, and in chicken isolates compared to human isolates, independent of the Campylobacter species. The Georgian strains showed high variability of multi-locus sequence types (ST), including novel STs. This study provides the first antibiotic resistance data from Campylobacter spp. in Georgia and addresses the need for follow-up monitoring programs.

Effects of probiotic (Lactobacillus plantarum and Bacillus subtilis) supplementation on mortality, growth performance, and carcass characteristics of native Vietnamese broilers challenged with Salmonella Typhimurium.

Probiotic species have been proven to be beneficial on broiler performance; however, most studies have focused on industrial chickens with fast growth, whereas little information concerning the use of these species on native chickens is available. This study aimed to investigate the effects of probiotics Lactobacillus plantarum (LP) and Bacillus subtilis (BS) on the mortality, growth rate, and carcass characteristics in native Noi chickens challenged with Salmonella Typhimurium. We divided 420 1-day-old Noi chicks into seven different treatment groups (n = 60): negative control (no S. Typhimurium, no probiotics or antibiotics); positive control (PC, S. Typhimurium infection, no probiotics or antibiotics); and S. Typhimurium infection and supplementation with LP, BS, LP + BS, enrofloxacin, and commercial probiotics, respectively. Treatment was for 96 days, and the chicks were orally challenged with S. Typhimurium at 22 days old. No deaths occurred during the 4 weeks post-infection in the negative control, LP, or LP+BS groups. The PC group had the highest mortality rate (20%). Re-isolation of S. Typhimurium from the liver, spleen, and heart showed reduced bacterial counts at 1 week post-infection in the LP, BS, and LP + BS groups. The lowest body weight gain was observed in the PC group (949 g/bird), and chicks in the LP group gained 1148 g/bird. An improved feed conversion ratio was noted in the groups receiving probiotic supplementation (3.42-3.50 kg feed/kg gain). There was little evidence that probiotics affected carcass percentage and related parameters, such as breast, thigh and drumstick, and wings. Lactobacillus plantarum or BS dietary supplementation to native Noi broilers resulted in a lower mortality rate and improved body weight gain but did not affect carcass characteristics.

Detection of toxoplasmosis in (Free living and Industrial) chicken of Qadisiyah province, Iraq

The study aimed to investigate the differences in the genetic tree of types infected (Free living and Industrial chickens) with the Toxoplasma parasite, (brain and liver) collecting samples in Al-Qadisiyah province during the period from October 2021 until the end of March 2022. A total of 90 samples of chicken were collected, 60 samples of brain and 30 samples of liver. The purpose of diagnosis, the impression method was used. It was found that 60 samples of free living chickens were all positive for examination. As for industrial chickens, 20 samples from 30 were positive at rate 88.8%, in rate of (83.3%) 50/60 from the brain and (66.6%) 20/30 from the liver. Nested PCR targeting aspecific region within SAG3 gene technique applied for detect the genotype of T.gondii, the results showed that 30/48 of the chickens (brain and liver) (62.5%) were positive. A genetic match was found between Toxoplasma gondii in chickens SAG3 gene and the gene isolates according to NCBI – BLAST.

Molecular detection of Toxoplasma gondii in chicken hearts from markets and retail stores in Northern Iran

Detection of Toxoplasma gondii in chicken products indicates risk of transmission to consumers. The objective of the current study was to investigate the molecular prevalence of T. gondii in free-ranging and industrial chickens in Guilan province, Northern Iran. A total of 150 chicken heart samples including 75 free-range and 75 industrial chickens were collected from farmers' markets and chicken retailers in Guilan, Northern Iran, between October 2017 and August 2018. Genomic DNA were extracted from samples and examined for evidence of T. gondii using polymerase chain reaction (PCR) targeting the B1 gene. The B1-positive samples were further analyzed by nested-PCR for SAG1 gene. Of the 150 samples, T. gondii DNA fragments were detected in 59 (39.3%), including 30 (40%) free-range and 29 (38.7%) industrial chicken. No significant differences of T. gondii DNA detection was observed between the free-range and industrial chicken samples (p = 0.73). Four selected positive samples were used for amplifying and sequencing of the SAG1 gene. The results revealed that all four sequences of SAG1 had 100% similarity with T. gondii sequences previously isolated from an AIDS/HIV patient in Mazandaran province, Northern Iran. Furthermore, the phylogenetic analysis demonstrated that all four sequences were closely related to Type I of T. gondii. However, our Type I identification is preliminary and needs to be confirmed by further multilocus sequence typing (MLST) analysis. The findings of the present study provide new data about the presence of T. gondii DNA in chicken hearts in the study area. These results confirm that chicken can be used as sentinels for environment contamination; however, further studies are needed to determine the viability of T. gondii in chicken hearts from Iran for risk assessment.

Efficiency of using probiotic Elac-grow and Han-proway in laying-egg hens

Industrial chicken farm has to face many challenges such as epidermis and environmental pollution. Antibiotics and synthetic antimicrobial agents are routinely used to alleviate stress as well as to elevate growth and feed efficiency. However, using antibiotic had many negative effects, especially antibiotic resistance; therefore, probiotic products are a bio-secure solution being popularly applied in livestock husbandry. The study was carried out on the two probiotics Elac-grow, a diet supplement, and Han-proway, a waste treatment product, in industrial egg-laying hens. There were two lodgings (test and control) in these experiments; each had 4000 23-week-old hens of Hyline breed. Two probiotics were applied to the test and none to the control. The results showed that there was not significantly difference of egg yield between the two groups, although, the test lodging had higher egg yield growing ratio (67.48%) than the control one (65.73%). Egg quality in the experimental lodging was also significantly improved in the damaged egg ratio, the egg weight and the egg yolk weight after using Elac-grow. The efficiency of using Elac-grow and Han-proway was also shown through the concentration of ammonia emission in animal lodging. The ammonia value of the test lodging was maximum 5 ppm and remained stable at this point, lower than of the control. This efficiency was shown significantly in the microbial fluctuation analysis, when the total bacteria and coliform counts were reduced in the test lodging sequentially above 1x108 CFU bacteria/g and above 1x107 CFU coliform/g, the control had uptrend sequentially above 2x109 CFU bacteria/g and above 1x108 CFU coliform/g.

Properties of Animal-Origin Ash—A Valuable Material for Circular Economy

In the presented paper, two types of animal-origin biomass, cow dung and chicken litter, are characterized in terms of combustion-related problems and ash properties. It was found that these parameters strongly depend on the farming style. Whether it is cow dung or chicken litter, free-range raw materials are characterized by higher ash contents than industrial farming ones. Free-range samples contain chlorine at lower levels, while industrial farming samples are chlorine rich. Free-range samples are characterized by the predominant content of silica in the ash: 75.60% in cow dung and 57.11% in chicken litter, while industrial farming samples contain more calcium. Samples were classified by 11 “slagging indices” based on the ash and fuel composition to evaluate their tendencies for slagging, fouling, ash deposition and bed agglomeration. Furthermore, an assessment was made against the current EU law regulations, whether the ashes can be component materials for fertilizers. The phosphorus concentration in the investigated ashes corresponds to 4.09–23.73 wt% P2O5 and is significantly higher in industrial chicken litter samples. The concentrations of Hg, Cu, As, Ni, Cd and Pb in all samples are below the limits of the UE regulations. However, concentrations of Cr in all samples and Zn in industrial chicken litter exceed these standards.

Environmental Injustice and Industrial Chicken Farming in Delaware.

Potential disparities in the distribution of poultry CAFOs (confined animal feeding operations) and meat-processing facilities across Delaware were explored with regards to sociodemographic factors including race, ethnicity, and socioeconomic status. We conducted buffer analyses of CAFO host census tracts alongside sociodemographic data in order to explore populations in proximity to the Delaware chicken industry. We conducted a hotspot analysis of CAFOs to find areas with large concentrations of poultry operations and applied zero-inflation regression models to determine if there's a relationship between sociodemographic composition and number of CAFOs/meat- processing facilities in Delaware. Median household income was lower in CAFO host census tracts than all others, and also lower than the state median. A larger percentage of people living in poverty are in poultry CAFO hotspots (15.4 percent) compared to the state average (13.7 percent). Delaware's chicken industry disproportionately burdens low-wealth communities. Delaware policy-makers should employ environmental justice-oriented solutions to best serve impacted populations.

New Green Animal Waste Hydrolysis Initiated by Malic Acid

Background: A giant amount of poultry waste represents one of the threats to the environment, or conversely, a significant source of peptides and other substances in demand. Rational use of huge quantities of poultry waste, especially after industrial chicken processing, is one of the pillars of biorefinery of animal wastes. Introduction: Six different animal wastes: chicken feathers, cartilages and the residue after meat separation, sheep wool, rabbit hair, and the rest of the goose feathers from blankets after cleaning were chosen for a hydrolysis test with malic acid as the initiator. Result: The newly designed hydrolysis of animal wastes at 140 oC with malic acid for initiation was successfully verified for all animal wastes. The resulting hydrolysates contained a mixture of amino acids, peptides, proteins, glycoproteins, and no salts. Conclusion: Hydrolysate applications for agriculture was successfully tested as a biostimulant in the form of a 10% water solution.

Environmental Injustice and Industrial Chicken Farming in Maryland.

Maryland’s growing chicken industry, including concentrated animal feeding operations (CAFOs) and meat processing plants, raises a number of concerns regarding public health and environmental justice. Using hot spot analysis, we analyzed the totality of Maryland’s CAFOs and meat processing plants and those restricted to the Eastern Shore to assess whether communities of color and/or low socioeconomic status communities disproportionately hosted these types of facilities at the census tract level. We used zero-inflated regression modeling to determine the strength of the associations between environmental justice variables and the location of CAFOs and meatpacking facilities at the State level and on the Eastern Shore. Hot spot analyses demonstrated that CAFO hot spots on the Eastern Shore were located in counties with some of the lowest wealth in the State, including the lowest ranking county—Somerset. Zero-inflated regression models demonstrated that increases in median household income across the state were associated with a 0.04-unit reduction in CAFOs. For every unit increase in the percentage of people of color (POC), there was a 0.02-unit increase in meat processing facilities across the state. The distribution of CAFOs and meat processing plants across Maryland may contribute to poor health outcomes in areas affected by such production, and contribute to health disparities and health inequity.

High Prevalence of Toxoplasma gondii in Industrial Tunisian Poultry Meat.

Food-borne Toxoplasma gondii infection is ranked among parasitic diseases of global concern. Toxoplasmosis is qualified as a one health disease, since it affects human health, animals, and ecosystems. The present study was performed to estimate the molecular prevalence of T. gondii in industrial poultry meat samples from Tunisia. A total of 140 breast samples were collected from chicken (Gallus gallus domesticus) and turkey (Meleagris gallopavo) and four breeding systems (broiler chickens, reform laying hens, chicken farm label, and broiler turkeys) cover the majority of chicken meat production in Tunisia. For each sample, DNA was extracted and T. gondii-specific PCR, targeting the B1 gene was performed. The overall molecular prevalence of T. gondii in poultry meat samples was 20% (28/140; 95%CI: 13.3-26.6%). The highest prevalence was observed in chicken farm label (25.7%; 9/35). Prevalence rates were 20.0% (7/35), 20.0% (7/35), and 14.3% (5/35) in broiler chickens, broiler turkeys, and reform laying hens, respectively (p > 0.05). Our finding suggests the involvement of industrial chicken meat, as a potential risk factor of human T. gondii transmission, especially when the latter is consumed undercooked.

Intensive animal farming operations and outbreaks of zoonotic bacterial diseases in Ukraine

In Ukraine zoonoses are a permanent threat to human health, some of them are bacterial diseases associated with farm animals. Complete avoidance of outbreaks of bacterial zoonoses is not possible but it is appropriate to study them to reduce the risks of transmission of zoonosis pathogens from industrial farms to the human population and the environment. The article highlights the results of a literature review on the potential role of industrial livestock farms in the spread of major bacterial zoonoses in Ukraine. About half of all of the country’s farmed animals are kept on farms using industrial technology; more than half of the establishments are classified as medium and large. The technology of keeping animals on such farms contributes to the development of diseases of obligate hosts caused by fecal bacteria. The systematic search and selection of literary sources, which are relevant to the topic of the study were carried out. The vast majority of analyzed publications are published in Ukrainian in local peer-reviewed scientific journals. An analysis of open-access official statistics from the state authorities of Ukraine was also conducted. The authors analyzed statistics and scientific papers published over the last 10–15 years discussing the outbreaks of food-borne zoonoses among humans and the studying their pathogens (Campylobacter spp., Salmonella spp., Escherichia coli (STEC strains), Listeria spp.) on industrial livestock farms. The main source of Campylobacter spp. and Salmonella spp. distribution are industrial poultry, including broilers and chickens, respectively. The STEC strains E. coli carriers are various types of farm animals, including cattle and pigs. The majority of infections documented in Ukraine are cases of salmonellosis in humans and animals. Despite reports of a significant prevalence of campylobacteriosis, colibacillosis and listeriosis in livestock farms, their association with outbreaks of food-borne zoonoses in humans remains poorly understood. The concept of an industrial livestock farm involves a permanent presence of a risk of outbreaks of bacterial zoonoses and their rapid spreading to the human population. This is due to concentrated maintenance of animals, standardized feeding, the priority of achieving the highest productivity of animals and economic indicators. Under such conditions, disturbance of hygienic norms and technologies significantly increases the risk of bacterial zoonoses on industrial farms. It is important to enforce the continuous control of the level of microbial pollution of farms, animal health, hygiene of milk production and processing, meat, eggs, etc. Farms have a negative impact on the ecological welfare of the surrounding territories. The problem of spread of antibiotic-resistant strains of bacterial zoonoses is a very serious one. Efforts for the formation of a national system of epidemiological supervision over bacterial zoonoses, comprising epidemiological, epizootological, ecological, microbiological, serological and molecular genetic monitoring, as well as the development on this basis of effective prophylactic and anti-epidemic measures are relevant and necessary.
