Salmonella outbreak in Peterborough, cases linked to restaurant: health unit

PETERBOROUGH, Ont. - A Peterborough restaurant is closed as health officials investigate an outbreak of lab-confirmed cases of salmonella.

The Peterborough County-City Health Unit wants to speak with anyone who became ill with symptoms consistent with salmonella after eating at Ming's Restaurant (at 554 Lansdowne Street West) on or after Nov. 27.

The health unit is seeking this information to prevent the spread of illness to others.

Symptoms of salmonellosis include sudden headache, fever, abdominal pain, diarrhea, nausea, and sometimes vomiting.

The symptoms can occur within six to 72 hours, but usually appear 12 to 36 hours after consumption of contaminated food or beverage.

These symptoms usually resolve without treatment, but the health unit says people with symptoms should wash their hands regularly and avoid preparing food for others.
