SEASONAL SAFETY ASSESSMENT OF DAIRY PRODUCTS BY MICROBIOLOGICAL INDICATORS
Following article is dedicated to seasonal dynamic of irregularities in dairy products for hygiene indicators 789 samples of products from retail chains of the Central region Russian Federation were studied in different seasons of 2018 for compliance with the requirements of microbiological safety. It was found that the bulk of the irregularities in the samples were caused by coliform bacteria with the maximum percentage of positive samples (29.7%) in spring compared to other seasons. It turned out that during this period, the most discrepancies in this indicator were found in dairy products and cheeses, 33.3 and 37.4 %, respectively. The largest share of the regulated nonconformances to identify the number of mesophilic aerobic and facultative anaerobic microorganisms were in summer months. It was shown that the increase in climate temperature also influenced on the growth of number of positive samples., The maximum percentage of samples exceeding the norms of sorbic acid content was also noted in the same products in the spring and summer periods.
