Danone Canada is recalling a brand of yogurt sold at Costco.
The recall notice was issued Monday through the wholesaler's website saying that Kirkland Signature Probiotic Yogurt (24x100g) may contain a type of yeast that could cause illness in people with a compromised immune system.
"The food safety risk is low as this yeast is not known to grow in refrigerated temperatures," the recall said.
The affected product was sold between September 3 and September 19 and has best-before dates of October 18, October 20, and October 22.
According to the yogurt maker, anyone who bought the product should not eat it and should return it to Costco for a full refund.
