Microbiological monitoring of the production environment at the Birsk Dairy Plant

This paper discusses the state of the production environment at the Birsk dairy plant. Milk and dairy products are one of the main human food products, and should be safe for microbiological indicators. Monitoring of the production environment was carried out to prevent secondary contamination of food with pathogenic microflora. The main methods of microbiological control in the production of dairy products that were used for the study are described. The paper presents the results of the sanitary and hygienic state of the air environment and drinking water of centralized water supply. Microbiological industrial monitoring of air and drinking water was carried out 4 times a year in the period from November 15 2019 to July 9 2020. 6 production facilities were selected for the study. During monitoring, microbiological parameters of the air environment were determined: NMAFAM (the number of mesophilic anaerobic and facultative anaerobic microorganisms), mold fungi and yeast. Microbiological parameters were determined in drinking water: total microbial number, total coliform bacteria, and thermotolerant coliform bacteria. The results of the analysis showed that the state of the production environment complies with all established norms and rules, and it is safe to produce dairy products in these conditions.
