VETERINARY AND SANITARY EXAMINATION OF THE QUALITY OF TILAPIA FISH GROWN IN PONDS

Abstract

The article presents the results of the veterinary and sanitary assessment of the quality of Tilapia fish grown in ponds in the conditions of the naturally hot East coast of the Almaty region. Two groups of fish were studied for different product groups. Sampling and organoleptic studies were carried out in accordance with the state standards in need. The research was carried out in the laboratory «Veterinary Dietetics and veterinary and sanitary examination of life-cycle products» of the Department of «Veterinary and Sanitary Examination and Hygiene» of Kaznayu and the laboratory of «AsylTasEngineering» LLP. During the bacterioscopic examination, the absence of microflora in the deep layers of meat was revealed. The content of amino-ammonia nitrogen in the experimental groups averaged 1.24±0.35 mg, i.e. the amount of amine-ammonia nitrogen was normal. When reacting with peroxidase, the filtrate turned blue-green, which turned brown after 1 minute, i.e., according to the results of the study, the reaction to peroxidase was positive in all groups. When reacting with hydrogen sulfide, all samples of the sample met sanitary standards. When determining the nessler population, it was shown that the filtrate obtained from fish of all groups was transparent, without turbidity and yellowing. During the organoleptic study of all the forms of the Tilapia rehearsal samples, positive results were obtained, i.e., according to the qualitative indicators, all the tests of the ripples met the sanitary requirements.
