The Canadian Food Inspection Agency updated a warning Monday for certain brands of frozen hamburgers.
The agency first said there was a chance they could be contaminated with E. coli on March 17.
The burgers originated from a plant in Ontario, identified as establishment 761.
According to the agency, several products sold in Quebec may be affected, including Irresistiblesbrand products sold at Metro, and a variety of President's Choice products, sold at Loblaws, Maxi and Provigo.
There has been one reported illness.
Food contaminated with E. coli does not necessarily look or smell spoiled, but the bacteria can cause serious and potentially life-threatening illness.
Symptoms may include severe abdominal pain, bloody diarrhea, seizures, strokes and permanent kidney damage.
