The ongoing multistate Escherichia coli O157:H7 outbreak linked to romaine lettuce from the Yuma, AZ, growing region has now crossed the U.S. border into Canada.
According to a May 9th public health notice posted by the Public Health Agency of Canada (PHAC), six E. coli illnesses have been reported in Canada--all of which have a similar genetic fingerprint to those reported in the U.S. romaine lettuce investigation. Now, PHAC is working with federal and provincial health officials to pinpoint the source of the illnesses.
