The London Free Press is reporting that the total number of Salmonella cases at the University of Western Ontario in London has climbed to 42 — an increase of 10 — and that none of the new cases is related to the Pita Pit, the source of the original cases.

Dr. Bryna Warshawsky of the Middlesex-London Health Unit was cited as saying the new cases involve people who ate food prepared at a central kitchen in the Centre Spot food court and distributed to other outlets on campus, and that the new cases could point to a cross-contamination at the Centre Spot, adding,

"There’s a wide variety of food items, purchased from a wide variety of places. The only common element is that the food was prepared within the Centre Spot."

Or a common ingredient. Maybe something like tomatoes? We await the public results of the health unit’s investigation.
