title: Hospital outbreak of clostridium perfringens food-poisoning.
abstract: An outbreak of Clostridium perfringens (C.welchii) food-poisoning affected a third of the patients in a large hospital, and one frail patient died. C.perfringens type A, serotype 1, was isolated from 46 (61 per cent) of 76 patients examined and from food, and a new serotype (61) was isolated from 16. The attack-rate among patients who ate a minced-ham dish was 78 per cent. The cooking and storage of this mince was faulty: cuts of meat were much too large, they were kept at room temperature too long before refrigeration, and after cooking they were put into mincers used also for raw meat. C.perfringens type A, serotype 1, was isolated from meat scraps in a mincer. Final reheating was inadequate to destroy even vegetative bacteria, and multiplication may have occurred during slow distribution to the wards. Outbreaks of C.perfringens fool-poisoning are common in hospitals, and some underlying problems are discussed. A plea is made for the Food Hygiene Regulations to apply to National Health Service premises and for simple but effective reforms in institutional catering management.
