The U.S. Food and Drug Administration has issued a Class I risk alert for hundreds of Alma Pak International LLC frozen organic blueberries after they tested positive for Listeria monocytogenes contamination.

Alma Pak International LLC issued a voluntary recall for 400 30-pound boxes of its organic frozen blueberries due to possible Listeria contamination.

In a statement announcing the recall, Alma Pak said the "affected frozen product was fully recovered before reaching the retail market, and as a result, no product was sold to consumers, and there was no risk to public health."

Alma Pak International added that, in close coordination with the U.S. Food and Drug Administration, the Georgia Department of Agriculture and an independent food safety consultant, the company conducted a thorough investigation and implemented corrective actions and preventive controls to strengthen its food safety systems.

The FDA announced it would escalate the action to a Class I status, which means there's “a reasonable probability” that use of or exposure to the products will cause serious adverse health consequences or death.

The firm received positive results for the bacteria on its finished products during routine testing. According to the enforcement report, the blueberries were sent to a single customer in North Carolina. A press release was not issued for the recall.

According to the CDC, listeriosis, caused by the bacteria Listeria, is the third-leading cause of death from foodborne illness in the United States. Each year, the CDC estimates that 1,600 people are infected with Listeria, and 260 die from the infection.

For questions or concerns about the recall, contact the FDA at 1-888-463-6332.
