Costco recalls 36,000 kg of butter due to missing 'milk' warning

Costco recalled nearly 36,000 kg of its Kirkland Signature Sweet Cream Butter due to the absence of an allergen warning for milk on the packaging. While butter is inherently a dairy product, FDA regulations require clear allergen labels to protect individuals with severe milk allergies. Consumers can return or dispose of the affected butter for a full refund.
