The Food and Drug Administration has classified a recall of eggs sold at Costco caused by potential salmonella contamination as the highest risk level for infection.

The voluntary recall last month was of 10,8000 cartons of Handsome Brook Farms eggs sold under the Kirkland Signature Organic Pasture Raised label.

The FDA defines a Class I recall as there being "a reasonable probability" that a recalled product "will cause serious adverse health consequences or death."

"The recall was initiated after the company determined that eggs not intended for retail distribution were instead packaged and distributed in retail packaging," Handsome Brook Farm said in a recall statement.

No illnesses were reported as of the Nov. 27 recall initiation.

The recall was initiated for 24-count packages of Kirkland Signature Organic Pasture Raised with a UPC of 9661910680.

The recall announcement states that the recall is only for cartons marked with Julian code 327 and a use by date of Jan. 5, 2025.

"No other products are impacted by this recall," the announcement said.

The recall announcement states the recalled eggs were sold in 25 stores in the following states:

Costco customers who have the recalled eggs should return it to their store for a full refund or dispose of the product, the announcement said.

Salmonella is a bacteria that can cause people to experience diarrhea, fever and stomach cramps. Symptoms can appear between six hours and six days of infection and will last for four to seven days, the CDC said.

Children younger than 5, the elderly and people who are immunosuppressed are more likely to have severe infections if they contract salmonella, the FDA said.
