This recall for “potential foreign material contamination” comes a month after nearly 9,000 boxes were pulled for manufacturing concerns.

Costco announced a recall of Kirkland Severe Cold & Flu Capsules due to the potential of foreign material contamination.

Costco recalled a Kirkland Signature brand cold and flu medication due to potential contamination. Kirkland Signature Severe Cold & Flu Plus Congestion capsules were affected. The contaminated capsules were accidentally released after they were rejected for potentially containing foreign matter.

Keeping cold and flu medicine on hand is common for many households this time of year. Having it stocked means someone can ease symptoms in a flash should they get sick. But one medication that was sold at Costco may do more harm than good if you have it tucked away in your medicine cabinet.
