An investigation of Salm. saint-paul infection in England and Wales in 1959 is described. In one-third of the human incidents the infection was attributed to home-produced meat coming from two infected abattoirs.
Animal infection was demonstrated and was probably due to contaminated imported animal feedingstuffs.
The clinical histories of 55 of the 89 cases reported during the year were studied. There was one death. In ten patients the illness commenced with fever and malaise and diarrhoea was absent or did not occur until 24–48 hr. later. One patient developed meningitis and another an abdominal abscess.
