Consumers should return the eggs to Costco or throw them away, and monitor for symptoms of Salmonella infection.
The Food and Drug Administration has set the Costco egg recall at the highest risk level over potential Salmonella contamination.
On Friday, the FDA updated the egg recall to class 1, meaning there's a "reasonable probability" that eating the eggs will "cause serious adverse health consequences or death."
On Nov. 27, Handsome Brook Farms voluntarily recalled 10,800 units of 24-count eggs -- for a total of almost 260,000 eggs -- sold under the Kirkland Signature brand at Costco over Salmonella concerns.
No illnesses have been reported to date in connection to the recalled eggs.
The affected eggs were sold in 25 Costco stores across five states, beginning on Nov. 22. With a use-by date of Jan. 5, 2025, the recalled eggs may still be in consumers' fridges.
The recall applies to Kirkland Signature Organic Pasture Raised 24-Count Eggs packaged in plastic cartons with the UPC 9661910680 and Julian code 327.
The FDA advises consumers to return the recalled eggs to their local Costco store for a refund, or throw them away.
The recalled eggs were sold at Costco stores in the following states:
If you think you may have consumed the recalled eggs, monitor for common symptoms of Salmonella infection, including fever, diarrhea (which may be bloody), nausea, vomiting, and abdominal pain.
Symptoms typically begin six hours to six days after consuming the contaminated food and go away within a week without medical treatment.
Young children, frail or elderly people, and others with weakened immune systems may develop more serious or life-threatening infections.
