The U.S. Food and Drug Administration (FDA) has upgraded a recall of eggs to its highest alert classification level.

In November, the agency announced a recall of New York-based Handsome Brook Farms organic pasture-raised eggs sold at Costco.

Over 10,000 Batches Of Organic Eggs Sold At Costco Recalled

"Handsome Brook Farms is voluntarily recalling 10,800 retail units of the Organic Pasture Raised 24-Count Eggs sold under the Kirkland Signature brand name because these eggs have the potential to be contaminated with Salmonella, an organism which can cause serious and sometimes fatal infections in young children, frail or elderly people, and others with weakened immune systems," the FDA previously stated.

"These units of the Kirkland Signature Organic Pasture Raised 24-Count Eggs were distributed into 25 Costco stores in the States of Alabama, Georgia, North Carolina, South Carolina, and Tennessee beginning November 22, 2024," it added.

Now, the FDA revealed on Monday it upgraded the recall's alert classification.

Independent reports:

The FDA revealed on Monday that the recall is now “Class I,” meaning this is a “situation in which there is a reasonable probability that the use of or exposure to a violative product will cause serious adverse health consequences or death.”

This is the most serious risk level that an FDA recall can be, with the classification change coming one month after 10,800 retail units of organic eggs were recalled from Costcos across the southern United States.
