No recall of romaine in Canada, but CFIA keeping tabs on E

Share

Previously, the warning applied only to chopped romaine, salads, and salad mixes. Therefore, consumers should throw out any romaine lettuce in their homes, even if partially eaten, and avoid eating romaine at restaurants unless the establishment can confirm that the lettuce is not from Yuma.

The first warning was issued on April 10, with 17 people infected across seven states.

At least 31 of those patients have been hospitalized, or 58% of the official total, which is a very high percentage of hospitalizations in an E. coli O157:H7 outbreak. Although there are no reported deaths yet, about ten percent of the affected consumers have developed hemolytic uremic syndrome, a type of lifelong kidney failure. More than 50 illnesses in 16 states are linked to the tainted lettuce, according to the CDC's last official count.

GREENSBORO, N.C. -If you have romaine lettuce or eggs in your fridge there's a good chance they could make you sick.

US health officials on Friday told consumers to throw away any store-bought romaine lettuce they have in their kitchens and warned restaurants not to serve it amid an E. coli outbreak that has sickened more than 50 people in several states. DNA fingerprinting is performed on E. coli bacteria isolated from ill people using techniques called pulsed-field gel electrophoresis (PFGE) and whole genome sequencing (WGS).

No common grower, supplier, distributor or brand has yet been identified.

The outbreak was originally thought to be connected to chopped romaine lettuce because that's what the restaurants served.

The CDC says that it can take an average of three to four days after coming into contact with E. coli for people to start feeling symptoms.

Matos said there is no association between the USA cases and an E. coli outbreak in Edmonton that has sickened 34 people, including 11 who were hospitalized and one patient who died, likely due to E. coli infection. The appeal by the CDC goes to the public, retailers, and restaurants.

This investigation is ongoing, and CDC will provide more information as it becomes available.
