Twenty-five samples of several types of meat purchased at supermarkets in Rio de Janeiro were analyzed for presence of Yersinia . Species were isolated from 80% of beef and chicken giblets, 60% of ground beef and beef liver and 20% of pork, Fifteen strains were identified as Yersinia intermedia , 9 as Yersinia enterocolitica , 4 as Yersinia kristensenii and 1 as Yersinia frederiksenii . Two strains of Y. intermedia , serotype 0:13,7 were positive in both the autoagglutination and calcium-dependency tests. Two strains of atypical Y. intermedia (serotype 0:29 and one not typable) and one strain of atypical Y. enterocolitica , serotype 0:16; were positive only in the auto-agglutination test. Seventeen strains isolated from meat produced heat stable enterotoxin.
