A recall of walnuts, other nuts and snack foods has expanded to include specific stores that repackaged the nuts.
The Canadian Food Inspection Agency's notice listed 21 stores in Ontario that sold affected products.
The agency also said that Carrousel Peanuts and Nuts Praline sold in the 680-gram package with a best before code of "2012/mar/25" were distributed in Quebec and New Brunswick.
People should not eat the walnuts and snacks listed because they may be contaminated with E. coli O157:H7.
Eating foods tainted with E. coli can lead to abdominal pain and bloody diarrhea. Some people may have seizures or strokes and some may need blood transfusions and kidney dialysis. Others may live with permanent kidney damage.
In severe cases of illness, people may die.
No illnesses related to E. coli-tainted walnuts have been reported.
The original recall began on Sept 1. At first, it only covered walnuts but it has expanded several times since then.
Johnvince Foods of Toronto imported the affected walnuts from California.
