Contamination of milk and its products with Yersinia enterocolitica at various stages of the production process was studied for the first time. Yersinia were detected in fresh milk (at dairy farms, in tanks at reception compartments of dairy plants) and in pasteurized milk (in tanks at the plant, in paper-bags on sale). All Yersinia strains isolated from milk are pathogenic for man and highly resistant to antibiotics. A possible role of man, in particular of workers at dairy farms and plants, in Yersinia dissemination, is shown. Unlike milk, sour milk foodstuffs virtually do not participate in propagation of the infection.
