ONTARIO: E. coli outbreak over, Mercer says - (GuelphMercury.com)
August 14, 2008 – 5:53 pmGUELPH — Dr. Nicola Mercer, medical officer of health WDG Public Health, has declared the E. coli outbreak at the University of Guelph over.
“We have waited two incubation periods and there have been no new exposures”, Dr. Mercer states. “The incubation period is the maximum amount of time that you can develop symptoms after exposure to the E. coli bacteria. The incubation period for E. coli is up to 10 days with the average being three to four days.”
Analysis of information collected by Public Health during the outbreak supports the theory that the contamination occurred during the week of July 20.
“We are still waiting for lab results for some people who experienced symptoms related to possible exposure during that period of time. The number of confirmed cases could change but the outbreak remains over unless new exposures are found.”
