Abstract
The Far East is home to special species of salmon fish and non-fish species, many of which are delicacies and are in high demand among the population. Such products are delivered to the central regions in a frozen form, which raises the issue of bacteriological safety during logistics, and the impossibility of full control over wild commercial species and the impact of human activity on their habitats creates the need to check toxicological and radiological safety. The article presents the results of organoleptic, toxicological and laboratory studies of frozen shrimp and semi-finished products (steaks) from some types of salmon fish caught in the waters of the Far East and sold in retail stores. Their safety and good quality have been proven. The organoleptic parameters corresponded to those required from fresh products, no pathogenic microorganisms were found in all samples, the concentration of hydrogen ions in the samples was in the range of 6,4–6,8, the amount of cesium-137 and strontium-90 in salmon fish samples was 5,6±22,3 Bq/kg and less than 0,1 Bq/kg, respectively, in shrimp samples – 0±13,7 Bq/kg and less than 0,1 Bq/kg, respectively. The results were obtained using generally accepted methods of veterinary and sanitary examination and were analyzed in comparison with the requirements established by these technical regulations and sanitary rules.
