BACTERIAL CONTAMINATION AND BIOLOGICAL SAFETY OF BREAM AND WALLEYE IN POSTDIPLOSTOMOSIS IN THE CONDITIONS OF THE KUIBYSHEV RESERVOIR

Fish and fish products are of no small importance as an obligatory component of the human diet. This is due to the fact that fish meat has a high nutritional and nutritional value. However, in some cases, fish is a source of infection for humans. This is the case with some parasitoses and infections. Fish parasitoses are quite widespread, both in natural reservoirs and in pond fish farms. Often, the course of parasitosis in fish is complicated by the addition of secondary microflora, which aggravates the pathological process and serves as a source of toxic infections for humans. The authors conducted a comparative analysis of microflora in postdiplostomosis of bream and walleye in the conditions of the Kuibyshev reservoir. During the research, an inventory of the microflora of sick fish was carried out. It is represented by microorganisms from two families - Enterobacteriaceae and Vibrionaceae and three genera Listeria, Pseudomonas, Staphylococcus. Contamination of organs and tissues of sick fish also has differences. The gills are maximally contaminated. Minimal contamination is inherent in the skin. In a fish with postdiplostomosis, the presentation is violated. In its raw, insufficiently boiled, fried, dried salted form, it is dangerous for humans as a source of helminthic invasion. The contamination of pathogenic and conditionally pathogenic microflora creates prerequisites for the development of toxic infections in humans when eating such fish.
