Оценка безопасности продуктов убоя при фасциолёзе крупного рогатого скота

Abstract

The aim of the study was a veterinary and sanitary assessment of meat and slaughter products in cattle fasciosis. To achieve the goal, depending on the intensity and extensiveness of fasciolous invasion, meat carcasses received by the laboratory of veterinary and sanitary examination of the market were divided into four groups: with a low degree of invasion; with a moderate degree of invasion; with a high degree of invasion and no signs of invasion. Safety assessment of slaughter products was carried out using organoleptic, physicochemical indices, bacterioscopic examination of smears and microbiological analysis of meat. As a result of the studies, it was found that the infection of cattle with fasciosis leads to changes in the organoleptic and physicochemical characteristics of meat. The strongest deviations in physicochemical indicators were recorded in the group with a strong degree of invasion: the reaction with copper sulfate and the formal reaction turned out to be slightly positive. In sanitary microbiological examination, no bacteria of the E. coli group, bacteria of the genus Proteus, bacteria of the genera Salmonella and Listeria monocytogenes were found in all the studied samples, indicating the safety of meat. However, the total bacterial obscurity in samples from carcasses of the group with a strong degree of invasion exceeded the normative indicators (3,0 103±0,18 KOE/g).Therefore, cattle meat with a high degree of contamination should be sent for industrial processing within five days after slaughter.
