FOOD POISONING.
There was this year, for the first time in several years,
one outbreak of food poisoning within the Borough which should be
reported, although it produced only one notification here, and was
due to Clostridium Welohii in frozen rabbit bought outside the
Borough. This outbreak occurred in the modern canteen of a worldfamous
firm, and affected 30 members of their staff.
One individual oase occurred in a man immediately on his
return from a Camp where other cases had been found. This was due
to salmonella typhi-murium, but of course the food implicated
could not be traced in this instance.
