Scombrotoxic fish poisoning: features of the first 50 incidents to be reported in Britain (1976-9).

Fifty incidents of scombrotoxic fish poisoning affecting nearly 200 people have been reported in Britain, the majority in 1979. Increased consumption of mackerel, inadequate storage conditions, and more general clinical recognition of the condition are considered responsible for the rise in outbreaks. Though the illness is generally not serious, it may be alarming and unpleasant and is totally preventable by proper attention to principles of hygiene at all stages of production, distribution, and storage.
