Infection of cyprinid fish with larvae of human-pathogenic helminths and bacteria in the Lower Volga River Delta at the present time
Recreational and artisanal fishing is very widespread in the Astrakhan Region; its primary targets are cyprinids, which are susceptible to epedemiological threats. Food products derived from the biological resources harvested during such fishing are not subjected to the processing in specialized facilities, and therefore, safety of the final product for its consumer cannot be ensured. In this region, the diseases, the agents of which are transmitted through fish and the products of its processing, are annually recorded among the population. Sanitary and parasitological control is one of the components in the set of measures for the prevention of these diseases. This work was aimed at evaluation of the infection level in some species of commercially valuable cyprinids in the Lower Volga River Delta with bacteria and larvae of pathogenic helminths capable of causing the development of diseases in humans. An incomplete helminthological survey of Caspian roach, common bream, white bream, crucian carp and rudd, as well as microbiological examination of their muscle tissue have been carried out in accordance with the requirements of the regulatory documents currently in force with application of methods described in State Standards. Larvae belonging to four species of human-pathogenic parasites have been recorded in the parasitic fauna of the Caspian roach, rudd, and white bream. Common bream was infected by larvae belonging to two species of such helminths. The identified larvae of pathogenic trematodes and nematodes were viable. The level of bacterial contamination of fish muscle tissues did not exceed the standard-prescribed limit, and the sanitary indicator microorganisms were absent. The results of the parasitological study indicated the need for mandatory disinfection of cyprinid fish from larvae of pathogenic helminths.

В Астраханской области очень широко распространено любительское рыболовство, объектами которого в основном являются карповые рыбы, обладающие высоким эпидемиологическим значением. Пищевая продукция из водных биологических ресурсов, добытых в результате любительского лова, изготавливается кустарным способом и не обеспечивает безопасности полученного продукта для потребителя. В регионе у населения ежегодно регистрируют заболевания, возбудители которых передаются через рыбу и продукты ее переработки. Санитарно-паразитологический контроль является одним из звеньев комплекса мероприятий по профилактике данных болезней. Целью работы было определение уровня заражения отдельных видов промысловых карповых рыб в нижней зоне дельты реки Волги личинками патогенных гельминтов и бактериями, способными стать причиной развития заболеваний у людей. Неполное гельминтологическое исследование воблы, леща, густеры, карася, красноперки и санитарно- микробиологическое обследование мышечной ткани рыб осуществляли в соответствии с требованиями действующих нормативных документов, используя гостированные методики. В паразитофауне воблы, красноперки и густеры зарегистрировано четыре вида личинок опасных для человека гельминтов. Лещ был инвазирован двумя видами таких личинок. Выявленные личинки патогенных для человека трематод и нематод были жизнеспособны. Уровень бактериальной обсемененности мышечной ткани рыб не превышал нормативного показателя, а санитарно-показательные микроорганизмы отсутствовали. Результаты санитарно- паразитологического исследования свидетельствовали о необходимости обязательного обеззараживания карповых рыб от личинок патогенных гельминтов.
