Class II Recall Issued on Nearly 80,000 Pounds of Costco Kirkland Signature Butter

If you’ve purchased any butter from Costco lately then it’s time to check your fridge. 

In early October, the FDA sent out an initial recall on Kirkland Signature butter, produced by Continental Dairy Facilities Southwest LLC. The recall is for 79,200 pounds of butter due to an undeclared allergen. According to the FDA, the packages of both salted and unsalted Kirkland Signature Sweet Cream Butter list cream as an ingredient, but may not contain the “Contains Milk” allergy statement visible on the packaging.

On November 7, the FDA classified the recall as Class II, which means it is “a situation in which use of, or exposure to, a violative product may cause temporary or medically reversible adverse health consequences or where the probability of serious adverse health consequences is remote.” 

The recalled products, which were both produced and distributed in Texas, includes 1,300 cases, (amounting to about 46,800 pounds) of Kirkland Signature Unsalted Sweet Cream Butter, and 900 cases (amounting to 32,400 pounds) of Kirkland Signature Salted Sweet Cream Butter. The products all come with “best by” dates between February 22, 2025 and March 29, 2025.

As the Centers for Disease Control (CDC) noted, milk is one of the main foods that “account for most serious allergic reactions in the United States.” 

“The symptoms and severity of allergic reactions to food can be different between individuals and can also be different for one person over time,” the CDC added. “Anaphylaxis is a sudden and severe allergic reaction that may cause death. Not all allergic reactions will develop into anaphylaxis and more than 40% (2 in 5) of children with food allergies in the United States have been treated in the emergency department.”

Though the FDA has not put out information on what to do if you have purchased these recalled items — nor has it shared if there have been any illness or adverse reactions from consuming the product — the usual course of action is to either discard them or return them to your place of purchase just in case.
