The food‐borne zoonoses are the most important zoonoses in England and Wales measured in terms of human morbidity and mortality and they include the most important emerging infections. Over the past decade there were over 100,000 laboratory reported cases of salmonellosis, about 1–5 per cent with serious extra‐intestinal complications with 427 registered deaths; there were nearly 90,000 Campylobacter infections. In salmonellosis the sources and modes of spread of infection are largely known, but veterinary and human public health measures have so far failed to control the disease. In Campylobacter enteritis however, the source and spread in most of the reported cases are unknown and control is not yet possible. Amongst the remaining less common food‐borne zoonoses, listeriosis and yersiniosis are most prominent. Both are increasing with food‐borne outbreaks of both infections having been reported, but the origin of infection of most cases recorded in England and Wales is not known. Of the new food‐borne or water‐borne diseases the most common are giardiasis and cryptosporidiosis but in neither is it clear whether the infections are predominantly of human or animal origin. The place of haemorrhagic colitis and of S. zooepidemicus infection is not yet apparent, both may emerge as important zoonoses. Streptobacillary fever, on the other hand, seems unlikely to recur with normal hygienic standards of water and milk supply. Of the occupational zoonoses Q fever and leptospirosis are the most important. Although only 1,330 cases of Q fever were reported in 10 years, it is a severe disease; 123 of them had endocarditis. Leptospirosis probably increased in incidence and emerged as a new disease of farmers and others working with cattle. S. suis type 2, a ‘new’ disease, remained a rarity. Zoonoses acquired from pets made up only a small proportion of human zoonotic infections and the only apparent change was an increase in psittacosis, the reason for which is unknown. Lastly, among the zoonoses acquired from wild and captive animals the viral haemorrhagic fevers have emerged as an important hazard in hospitals and laboratories.
