(CNN) Federal officials are warning consumers to avoid certain brands of frozen berries sold at Kroger and other grocery stores over fears of Hepatitis A virus contamination.

The berries were sold nationwide under the grocery store's "private selection" brand. The contamination was discovered during a frozen berry sampling by the Food and Drug Administration, the grocery chain said.

"These products are available at Kroger and other retail locations and have a two-year shelf life ... The FDA is continuing to investigate to determine whether there are other implicated products," the FDA said.

The recalled brands are the private selection frozen triple berry medley, the private selection frozen triple berry medley and the private selection frozen blackberries.

There have been no reports of hepatitis A linked to the consumption of the items, the FDA said.
