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.

Costco recalled 80,000 pounds of butter whose packaging omitted the allergen warning 'Contains Milk.' It follows a far worse packaging error from Mattel last week.

Both butters affected listed cream as an ingredient, but did not contain an allergen disclaimer regarding milk, the FDA said.
