Three children have been infected with E. coli here in less than a week, prompting health officials to issue a warning.
The Middlesex-London Health Unit says the cases are unrelated but three instances of the bacterial infection at the same time is unusual.
In two of the cases, a spiced ground beef dish known as kofta was consumed from a Halal food store. The source of the third child's infection is still unknown.
The health unit is advising the public to stay away from ground beef purchased from the Westmount Halal Food Store in London, and to ensure all beef is cooked to appropriate temperatures.
