A consumer report of an allergic reaction to an undeclared peanut ingredient prompted Indigo Natural Foods Inc. to recall an undisclosed volume of debittered brewers yeast yesterday.

The company distributed the Indigo Packaged Goodness branded yeast to retailers in Ontario, according to the recall notice posted by the Canadian Food Inspection Agency (CFIA). The notice urges consumers to check their homes for the recalled yeast, especially if someone in their household has a sensitivity or allergy to peanuts.

“If you have an allergy to peanuts do not consume the recalled product as it may cause a serious or life-threatening reaction,” according to the recall notice. “Check to see if you have recalled products in your home. Recalled products should be thrown out or returned to the store wher they were purchased.”

Federal law in Canada requires that a variety of known food allergens, as well as all gluten sources, be declared on food labels. Peanuts and ingredients made with peanut products are among the known allergens subject to the labeling requirements.

The Canadian Food Inspection Agency is conducting a food safety investigation, which may lead to the recall of other products. If other high-risk products are recalled, the CFIA will notify the public through updated Food Recall Warnings.
