Introduction. To date, one of the priority tasks of the agro-industrial complex of Ukraine is to provide the population with benign and safe environmental and veterinary-sanitary products of animal products. Aquaculture is one of the fastest growing industries in the rapidly developing agro-industrial complex. The mentioned industry is able to provide the population with high quality nutritious and dietary fishery products in a relatively short period. Fish products replenish the human diet with essential amino acids, polyunsaturated fatty acids, trace elements and other nutrients to meet the needs of the body. But important indicators are the quality and safety of fish and fish products. The use of hazardous fish products by humans can lead to human diseases. Therefore, research on determining the safety and quality of fish remains an important link. The goal of the work. The purpose of our research was to investigate commercial fish sold in the Sumy trade network and to carry out its veterinary and sanitary evaluation. Materials and methods of research. These studies were conducted under the conditions of the Department of Veterinary Expertise, Microbiology, Zohygiene and Safety and Quality of Livestock Products of Sumy National Agrarian University and in Sumy Regional State Laboratory of the State Consumer Service. Conducted research on commercial fish, which came to the sale in the trade network of the city of Sumy, namely in supermarkets, specialized stores and agri-food markets. Fresh, dried and frozen fish were studied.. Results of research and discussion. As a result of the study of the selected samples was found in live fish, namely the fathead, characteristic signs of postodiplastomosis. This disease manifested itself as small black spots on the body of a fish. It was also revealed in the study of carp in two specimens that the chronic course of aeromonosis was manifested by the presence of fissured ulcers on the body of the fish. Since the detection of the disease did not spoil the product indicators of fish, then all living fish are allowed to sell. When examining dried fish, no deviations from the requirements for dried fish were found in the submitted samples. All fish are identified as benign and admitted for sale. Studies of fresh frozen fish (hake) revealed the presence in the muscle tissue of the nematode Contracoecum squalii Affected fish are characterized by an increased content of microorganisms in the deep and superficial muscle layers, a doubtful or negative reaction to peroxidase, a doubtful or substandard reaction with a Nesler reagent, a doubtful or substandard reaction with sulfuric acid, acidification. Conclusions and prospects for further research: 1. In a study of 323 samples of live, dried, frozen fish, which entered the trade network in Sumy, it was found that 8 (2.47%) samples did not correspond to good-quality fish.2. Signs of diseases characteristic of aeromonosis (2 specimens), postodiplastomosis (1 specimen) and contracenosis (5 specimens) were established in the selected fish samples.3. A batch of hake (170 kg) in which the pathogen Contracoecum squalii was detected is not allowed for sale and is intended for technical disposal. In the future, it is planned to develop and implement a permanent monitoring system for the quality and safety of fish and fishery products that are commercially available.
