Summary. Raw milk, which is a unique food product in its composition and taste, occupies an important place in the diet of most countries of the world and is used for feeding farm animals. Currently, the quality and safety of raw milk require constant monitoring at all stages of its production to prevent food poisoning caused by enterotoxigenic staphylococci. Outbreaks of such poisoning often lead to hospitalization of patients, therefore, the separation of staphylococci into pathogenic and non-pathogenic species is of great epizootological and epidemiological importance. Most staphylococci are the usual microflora of mucous membranes and skin without the causative agent of the disease. However, food intoxication caused by enterotoxigenic strains of staphylococcus, especially the species staphylococcus aureus, represents a separate group of diseases of this kind. A considerable part of enterotoxigenic staphylococci does not belong to the species staphylococcus aureus and even to coagulase-positive staphylococci in general. According to some data, 11.2% of enterotoxigenic cultures of staphylococci that cause food intoxication are coagulase negative. From all of the above, it becomes obvious that it is necessary to conduct studies of coagulase-negative enterotoxigenic staphylococci in raw milk in order to detect them in a timely manner and prevent toxicoinfections and toxicoses associated with dairy products.

Keywords: raw milk, bulk milk, milk products, dairy farms, staphylococcus, toxicoinfections, coagulase-negative staphylococci, Moscow region.
