Evaluation of contamination of cow milk with various conditionally pathogenic microflora for mastitis: genera Staphylococcus

Abstract

The food safety issue of livestock products concerning insemination by opportunistic and accompanying microflora has attracted increasing attention from specialists. The ever-increasing trade and export of dairy and meat products from Ukraine to the EU countries requires constant monitoring of inoculation with mesophilic-aerobic and facultatively anaerobic microorganisms and psychrophilic microorganisms, in particular the genera Listeria and Yersinia, which survive and multiply at low temperatures and in salted and fermented products and pose a threat to human health. Milk and lactic acid products make up a significant part of the diet of a modern person. Therefore, constant control of raw materials from dairy enterprises for the production of milk and directly at enterprises for its processing is a guarantee of food safety. At the stage of milk production, due to violations of technological cycles of production (mastitis and contamination with antibiotics) and the spread of several diseases in Ukraine (paratuberculosis, tuberculosis, leptospirosis, brucellosis), milk from a herd of dairy cows poses a significant threat to human health due to the danger of mastitis milk and milk containing the causative agents of tuberculosis, brucellosis, leptospirosis, and recently there are more and more reports about the association of bovine paratuberculosis and human short bowel syndrome (Crohn's disease) mainly among the young population of Europe, which may be due to extreme variability and adaptive capacity mycobacteria.
