(CNN) – Federal officials warn consumers to avoid certain brands of frozen berries sold to Kroger and other grocery stores for fear of contamination by the hepatitis A virus.

The berries have been sold nationwide under the brand "private selection" of the grocery store. The contamination was discovered during a sampling of frozen berries by the Food and Drug Administration, the grocery chain announced.

"These products are available at Kroger and other outlets and have a shelf life of two years (…)." The FDA continues its research to determine if there are any other products, "said the FDA.

The recalled brands are the triple frozen mixed-selection berries, the triple frozen mixed berries of the private selection and the frozen blackberries of the private selection.

No hepatitis A related to the consumption of these products has been reported, the FDA announced.

Fever, headache, fatigue, loss of appetite, nausea, vomiting, diarrhea, abdominal pain and yellowing of the skin or eyes are some of the symptoms of hepatitis A.

"The hepatitis A virus can cause an infection of the liver that may be unapparent.However, when the symptoms appear, their severity can range from a mild illness of a few weeks to a serious illness of several months" , said the FDA.

Consumers who ate the recalled frozen berries are advised to consult their health care professional to determine if vaccination is appropriate. Those with symptoms should receive treatment immediately.
