MICROBIOLOGICAL SAFETY OF MEAT AND MEAT PRODUCTS AT THE RETAIL MARKET IN LATVIA Aigul Maldybayeva, Ainura Taipova, Margarita Terentjeva Research for Rural Development, 2025 Microorganisms significantly affect the quality and safety of meat and meat products; therefore, detection of microbiological contamination is important to assess the safety of retailed products. The present study was aimed to detect microbiological contamination of raw meats and processed meat products purchased from supermarkets and farmers' markets during 2024- 2025 in Latvia. Raw meat included poultry, beef, and pork, but meat products were smoked ham, smoked and boiled sausages, pâté, cutlets, and meat balls. Samples were investigated according to the International Organization of Standardization (ISO) methodology and detected microorganisms and microbial groups were the total microbial count (TVC), Enterobacteriaceae, E. coli, Salmonella spp., Listeria spp. and Yersinia spp. All purchased meat products had acceptable microbiological quality in terms of TVC, Enterobacteriaceae and E. coli. The highest TVC levels were recorded in raw meat samples, while the highest concentrations of Enterobacteriaceae were found in raw meat obtained from farmers' markets, supermarkets and retail stores. The highest levels of E. coli were found in raw meat and processed meat. Differences in microbial contamination of meat and meat product could be related to the processing and hygienic practices at the retail level. Higher microbial contamination rates for raw products at the farmer market could be explained with difficulties to provide an adequate level of hygiene at the farmer markets in comparison with supermarkets.
Enhancing Animal Welfare and Immune Health: A Study on Hydrogen Peroxide and Iodine-based Disinfectants in Farms , M.R. Turabekov, B.B. Barakhov, , Zh.B. Myrzabekov, , O.O. Tagayev, , P.Sh. Ibragimov, , G.E. Alpysbayeva, , D.D. Narbayeva, , K.D. Alikhanov, , A.A. Taipova, and Engineered Science, 2024 Microbial contamination in agricultural environments poses a significant challenge, impacting both animal health and overall biosecurity.The study conducted at "Aidarbaev E.S." and "Agrofarm Dinara" revealed a significant accumulation of microorganisms on floors and walls, with concentrations ranging from 32.4 x 10 3 to 45.6 x 10 3 , while microbial counts were comparatively lower at drinking bowls.The application of a hydrogen peroxide-based disinfectant in the wet method demonstrated an average disinfection efficiency of 79.3%, surpassing other tested agents.Furthermore, the foam method using the same hydrogen peroxide-based composition exhibited a higher efficiency of 86.2%, highlighting its superiority over wet disinfection by 6.9%.Additionally, the iodine-based disinfectant composition, at a concentration of 0.5%, demonstrated a substantial impact on poultry houses and barns, reducing microorganism counts by 72.1% to 76.5% after a 3-hour exposure.Importantly, this disinfection process had no adverse effects on the physiological and clinical status of animals and birds, with hematological and biochemical indicators suggesting an improvement in the immune system by 9.2% in birds and 16.8% in dairy cows.Overall, our findings emphasize the effectiveness and safety of hydrogen peroxide and iodine-based disinfectants in enhancing biosecurity and animal health in agricultural settings.
Development of a Disinfectant Composition Based on Hydrogen Peroxide , G.E. Alpysbayeva, M.R. Turabekov, , B.B. Barakhov, , Zh.B. Myrzabekov, , P.Sh. Ibragimov, , O.O. Tagayev, , K.D. Alikhanov, , D.D. Narbayeva, , A.A. Taipova, and Engineered Science, 2024 The article presents the results of laboratory tests of a new disinfectant developed based on hydrogen peroxide to disinfect veterinary inspection facilities.Purpose of the study -creating unique, highly effective, cheap, multifunctional, and environmentally friendly disinfectants is an essential area of research in veterinary sanitation and disinfection of veterinary inspection objects.Preparations of this type include a newly developed disinfectant composition based on hydrogen peroxide.Hydrogen peroxide is a broad-spectrum antimicrobial agent.The scientific novelty of this work lies in creating a disinfectant composition that works comprehensively against microorganisms, and the drug can be used in the presence of animals.As a result of the study, the effectiveness of the new disinfectant was determined by the high bactericidal activity by diffusion into agar (the diameter of the growth inhibition zones is 21 mm for E. coli and 20 mm for St aureus) and at a 0.1% concentration, complete death of E. coli occurs and Staphylococcus aureus for 60 minutes.One of the important criteria for assessing the disinfection effect is the phenolic coefficient, which, for a composition based on hydrogen peroxide, the bactericidal effect of the drug under study exceeds the bactericidal effect of phenol by 24.81 and 20.66 times about E. coli pcs.1257 and St.aureus 209-P, respectively.The results obtained during the development of modes of use of the disinfectant in laboratory conditions made it possible to preliminarily determine the working concentrations and consumption of the drug per 1 m 2. The product under study amounted to 1-3% concentration with exposures of 30 minutes and at consumption of 0.5 l/ m2.
Marking of Genetic Resistance to Chlamydia, Brucellosis and Mastitis in Holstein Cows by Using Polymorphic Variants of LTF, MBL1 and TLR9 Genes Indira Beishova, Birzhan Nurgaliyev, Alena Belaya, Gulzhagan Chuzhebayeva, Vadim Ulyanov, Tatyana Ulyanova, Alexandr Kovalchuk, Laura Dushayeva, Kenzhebek Murzabayev, Ainura Taipova, Aizhan Zholdasbekova, Azamat Isabaev American Journal of Animal and Veterinary Sciences, 2023 The purpose of the research is to study the association of polymorphic variants of the Toll-Like Receptor 9 (TLR9), Mannose-Binding Lectin 1 (MBL1), and Lactoferrin (LTF) genes with the incidence of chlamydia, brucellosis and mastitis in Holstein cows. Samples of Holstein cows with established diagnoses of chlamydia, brucellosis, and mastitis were characterized by the nature of the correspondence of the observed frequencies of genotypes theoretically expected by the Hardy Weinberg law, by the percentage of genotypes in comparison with the control group of healthy animals, as well as by the nature of the distribution of relative frequencies of alleles of the studied genes. It was found that the genotypes TLR9-BfaIAA and MBL1-HaeIIICC were the genetic markers of increased resistance to chlamydia. The genotypes TLR9-BfaI AG and MBL1-HaeIIITT were the genetic markers of an increased risk of chlamydia. The genotypes MBL1-HaeIIITT and LTF-EcoRIAA were the genetic markers of an increased risk of brucellosis. The genotypes MBL1-HaeIIITC and LTF-EcoRIAB were the genetic markers of increased brucellosis resistance. The LTF-EcoRIAA genotype was a genetic marker of an increased risk of mastitis and the LTF-EcoRIAB genotype marked increased resistance to mastitis in Holstein cattle.
