Costco recalled nearly 80,000 pounds of store-brand butter last month because the product's label was missing a key ingredient: milk.

Save the addition of salt, spices and other add-ins for taste, butter is a single-ingredient food. So, it may come as a surprise that on October 11, the FDA recalled 80,000 pounds of Costco brand butter for containing its only ingredient: milk.

The FDA recently recalled 79,200 pounds of Costco’s sweet cream butter because the label didn’t include “the contains milk statement.”
