ISOLATION OF YERSINIA-ENTEROCOLITICA ANIM AL ORIGIN FOODS

The Authors have carried out a survey for the presence of Yersinia ent erocolitica in 162 chicken carcasses and 155 samples of ground meat, g iblets and raw sausages. The food samples were collected from two publ ic canteens and various retail stores in the Urbino area. Y. enterocol itica was isolated in 4.73% of the samples and all strains were biotyp e 1. The research confirms a low presence of the microorganism in the area examined and a scarce role of this foods in the spreading of micr oorganisms and, therefore, in the occurrence of human gastroenteritis.
