For the second time this month, yogurt from Costco is being recalled in Canada.

A notice was posted on the wholesale retailer’s website on Sept. 23 explaining that affected Kirkland Signature Probiotic Yogurt may contain a type of yeast that could make immunocompromised people sick. The yogurt, which comes in a 24-pack of 100-gram servings, could have been on shelves at a Costco warehouse in Canada between Sept. 3 and Sept. 19.
