Clostridium welchii food poisoning.

摘要: 1. Outbreaks of mild food poisoning have been investigated in which heat-resistant Cl. welchii appeared to be the causative organism. The outbreaks were characterized by colic and diarrhoea without vomiting, commencing 8–20 hr. after ingestion contaminated food.2. strains concerned are only feebly toxigenic, apart from heat-resistance their spores, some colonial characters, fit well into Type A. toxin production serology is uniform within an outbreak.3. Mild similar that seen natural epidemics has produced volunteers cultures isolated meat.4. Infection almost invariably due meat boiled, steamed, braised, stewed or insufficiently roasted, allowed cool slowly, eaten next day, either cold reheated.5. this kind should prevented cooking immediately before consumption; or, if impossible, cooling cooked rapidly keeping it refrigerated until required for use.
