The Food and Drug Administration is using its most severe notice in a recall of more than 6,000 bags of chips in two states because of “undeclared milk.”

The Food and Drug Administration (FDA) has ordered the recall of Lay's potato chips in Oregon and Washington due to the presence of an undeclared ingredient that could be harmful to health. Consumers are advised to check their pantries and dispose of any bags of Lay's potato chips that match the description of the affected product.

According to the FDA, If consumers have an allergy or sensitivity to milk, they should not consume the product and discard it immediately.
