[Zoonotic infections in persons working in plants producing meat and bone meal]

The present study has revealed that persons working at offal and bone processing plants show no specific pathology, peculiar to such plants, in the state of their health and severe mass diseases among these persons are absent. Nevertheless, rather frequent occurrence of erysipeloid should be noted. The survey of workers employed at different stages of the production process has revealed the presence of ornithosis, listeriosis and leptospirosis infections. No clinically manifest cases of these diseases have been detected. The infection of individual workers occurs in the process of production as the result of contacts with infected raw materials of animal origin. For preventing the possible spread of infection great attention should be paid to sanitary, hygienic and epidemiological measures.
