Federal health officials say Canadians have been stricken by a strain of E. coli with an identical genetic mic to romaine lettuce in the US southwest that's sickened 149 individuals in 29 nations.
Sixty-four people have been hospitalized, the CDC said and 17 of those have developed hemolytic uremic syndrome, a form of kidney failure that can be life-threatening, although most people recover in a few weeks.
As previously reported, data indicates that the contaminated romaine lettuce originated from the Yuma, AZ, growing region.
Two of the six people who became sick reported travelling to the US before they became ill, according to the Public Health Agency of Canada.
The CDC is urging people to throw out Romaine lettuce in their fridge. The agency says the last illness started back on April 25, and that "illnesses that occurred in the last two to three weeks might not yet be reported".More news: Vasyl Lomachenko KO's Jorge Linares
This article has been adapted from its original source. This is the largest E. coli outbreak in the United States since 2006.
"Most people reported eating a salad at a restaurant, and romaine lettuce was the only common ingredient identified among the salads eaten". These include stomach cramps, diarrhea, and vomiting.
It develops within a week after E. coli symptoms first appear. Even if the person with symptoms does not recall eating any lettuce, if they develop symptoms of E. coli infection, it is important to stay hydrated and treat them seriously.
"Product labels often do not identify growing regions; so, do not eat or buy romaine lettuce if you do not know where it was grown".
The CDC regularly publishes any new updates in the outbreak and has advised against buying or eating any romaine lettuce that you can not confirm came from outside the Yuma region.
LGMAs from Arizona and California and other industry groups recently offered to share information with public health agencies to figure out how romaine lettuce from the Yuma area may have been the cause of the current outbreak.
