Comparative Evaluation of Diagnostic Methods for Trichinellosis in the Meat From Wild Animals

Trichinellosis is widespread in natural environments and natural biocenoses as a zoonosis and has important epidemiological and epizootological significance. In Russia, trichinellosis has been recorded in more than 50 species of wild and domestic animals. Uncontrolled use of meat products from wild animals as well as insufficient thermal meat treatment can result in infection foci among humans, therefore early diagnosis of the disease is important. The article discusses three main diagnosis methods of trichinellosis in meat from wild animal: compressor trichinelloscopy, the method of digestion in artificial gastric juice (AGJ) and the AGJ digestion method using a Gastros-2M single-reactor device. The study object was a meat sample from a wild boar obtained on a hunting farm. The evaluation of the above methods recorded the time of the study, its usability, and cash expenses. The comparative assessment result showed that the fastest and most effective method for identifying Trichinella larvae in meat was the digestion in artificial gastric juice using the Gastros-2M device. However, it was noted that the compressor trichinelloscopy was more appropriate in single studies since it did not require costs for reagents.
