The retailing chain has recalled 80,000 pounds of butter because its packaging omitted an allergen warning. It follows a more dramatic packaging stumble from Mattel last week.

Costco voluntarily recalled 79,200 pounds of two types of its store-brand butter over the past month because their labels may not have said the products contain milk.

Continental Dairy Facilities Southwest, LLC recalled nearly 80,000 lbs of Costco butter on October 11. The firm-initiated recall on Costco Kirkland Signature Salted Sweet Cream Butter and Unsalted Sweet Cream Butter was enforced due to a missing disclaimer about milk as an ingredient.
