COMPARATIVE EFFECTIVENESS OF GASTROS AND AVT-L TYPE DEVICES FOR TRICHINELLOSIS DIAGNOSTICS

Abstract

The purpose of the research is to compare diagnostic and design characteristics of Gastros and AVT-L devices in order to determine the prospects for improving the veterinary and sanitary examination of carcasses with trichinellosis. Taking into account the requirements for ensuring the safety of food products, in particular meat and meat products, special requirements are imposed on the quality of trichinelloscopic control in the conditions of veterinary diagnostic laboratories of meat processing enterprises, markets and slaughterhouses. For this purpose, a fairly wide range of devices is used for both compressor trichinelloscopy and peptolysis of muscle tissue. Comparative tests were carried out for Gastros of Petrolaser LLC and AVT-L (VNIIP) type devices used for this purpose. In the process of work, we analyzed the features of the examination technology, the structural elements of the devices and the diagnostic efficiency. In general, the devices met the requirements of the veterinary and sanitary examination for trichinellosis in various production conditions, however, their design for manufacturability had significant differences. With equal diagnostic efficiency, the devices have significant design differences regarding the type of thermal stabilization, automation, control systems for the duration of the peptolysis and settling of the medium, and the dimensions of the devices. According to these parameters, Gastros is more promising at the present time. AVT-L requires some improvements.
