The Food and Drug Administration is investigating an outbreak of Hepatitis A linked to a frozen organic berry mix sold at Costcos in Hawaii.

State Health officials say they are investigating two cases of people who may have contracted the illness from the product.

Both patients are adults — one lives on Oahu, the other on Kauai. Dozens more cases on the mainland are linked to Townsend Farms Organic Anti-Oxidant Blend, which contains pomegranate seed mix.

The company has removed the product from stores and is attempting to contact members who purchased the product in recent months.
