The Food and Drug Administration has upgraded a recall of eggs sold at Costco to the highest risk level over fears of salmonella contamination. The agency classified it as Class I because “there is a reasonable probability” that it “will cause serious health consequences or death.”

Costco egg recall raised to highest risk level due to salmonella contamination

Handsome Brook Farms issued a voluntary recall of 10,800 retail units of Kirkland Signature Organic Pasture Raised eggs in November, according to a statement from the FDA. “The recall was initiated after the company discovered that eggs not intended for retail distribution were instead packaged and distributed in retail packaging,” the company said in a statement at the time, according to USA Today.

The eggs, which were sold at 25 Costco stores in five states, were recalled due to fears of “salmonella contamination,” the New York-based company added. The recall has been initiated for 24-packs of Kirkland Signature Organic Pasture with UPC number 9661910680. The affected products had the Julian code 327 and a best-before date of January 5, 2025.

What are the symptoms of salmonella?

Salmonella is a bacteria that causes a disease called salmonellosis. According to the CDC, those infected suffer from diarrhea, fever and stomach cramps. Although it is a common infection, salmonella sometimes causes infections in the urine, blood, bones, joints, or nervous system (spinal fluid and brain) and serious illness.
