SARCOCYSTOSIS OF WATER-FOWL IN THE TERRITORY OF THE KURGAN REGION

Abstract

Wild duck meat is a popular dietary product, complete in amino acid composition, rich in vitamins of group B, macro- and micro-elements, essential fatty acids. When eaten, such meat should be safe for humans. Sarcocystosis is a zooanthroponotic disease. The causative agent in ducks is S. rileyi. The definitive hosts are domestic and wild carnivores, as well as humans. Intermediate hosts are herbivores, reptiles, mammals, rodents, omnivores. The contamination of birds with sarkosporidii can reach up to 70%. The pathogen is characterized by interspecific specificity. The diagnosis of sarcocystosisis is based on the results of dissection and microscopy. In the territory of the Kurgan Region, sarcocystosis was recorded in two drakes of the mallard and of the common shoveler female, by the detection of multiple muscle cysts in skeletal muscles as a result of the opening of the carcass. Extensiveness of invasion with sarcocystosis was 8% in 2016, 2.7% in 2017. Infected carcasses have an unpleasant, sour muscle odor. The muscles in the incision are sticky, flabby in texture, when pressed with a spatula with a slow recovery of the fossa. To eliminate the spread of helminthiasis, it is necessary to develop effective control and prevention measures against it. Meat of a wild bird without fail should pass Veterinary and Sanitary Expertise. In the case of sarcocystosis, it is prohibited to use such meat for human and domestic animals. Disposal of carcasses affected by sarkosporidia should imply that homeless and wild animals cannot access it. Sarcocytosis duck meat must be disposed of by burning or burying it in pits to a depth of at least 2 m.
