The number of confirmed cases of salmonella food poisoning at the University of Western Ontario climbed by six yesterday, bringing the total number of lab-confirmed cases to 70, with more than 50 others who haven’t been tested, but show symptoms consistent with salmonella infection.

Bryna Warshawsky, associate medical officer of health with the Middlesex-London Health Unit, said it’s hard to tell if the outbreak is starting to slow, adding,

 "You can’t really judge that until you have seen several days of consistent numbers. We would like to get down to zero. We are hoping as we get into next week and more than a week past the thorough cleaning and disinfection that we will get down to zero."

It may require more than cleaning. Check employee practices and the food safety standards of suppliers, especially fresh fruits and vegetables.
