An outbreak of infection due to Streptococcus zooepidemicus (Lancefield Group C) is described. At least 11 patients were affected and the infection was responsible for, or contributed to, the deaths of seven of these. Clinical features included septicaemia, meningitis and endocarditis. The source of infection was unpasteurized milk from a dairy herd with mild intermittent mastitis. © 1988, Cambridge University Press. All rights reserved.
