[First isolation of Yersinia enterocolitica in several horticultural products intended usually to be consumed fresh].

A survey has been carried out for the presence of Yersinia enterocolitica in horticultural products. 60 samples of these vegetables have been examined among the families of Compositae (lettuce, prickly lettuce, cabbage lettuce, common chicory), Ombrelliferae (curly parsley, carrot, celery, fennel) and Crociferae (garden cabbage). This is the first isolation of Y.e. from horticultural products, being recorded 7 strains from carrots (serotype 0:6,30), 1 from curly parsley (serotype 0:4,32) and 1 from celery (serotype 0: 7,8). 0:6,30 is the most frequently isolated serotype from humans after 0:3 and 0:9 (especially in Canada), and has been recovered from four cases of human infection. Its presence in carrots may strongly assume a significance of clinical importance.
