FOOD POISONING
There was one outbreak in an industrial canteen the details of
which are given on the following page. In the family outbreaks it was not
possible to obtain specimens of infected food, but a history of faulty
hygiene was obtained in a number of cases. It is possible that in many
of these cases the original source of infection is a carrier within the
family. A slip in normal precautions leads to infection of the family's
food and there is then a family outbreak. In some cases perhaps the food
handler poisons only himself or herself and only one case is notified.
