Nature's Touch brand Organic Berry Cherry Blend, sold at Costco locations in several provinces, is being recalled due to possible hepatitis A contamination, the Canadian Food Inspection Agency announced on Friday.

The product has been sold in New Brunswick, Nova Scotia, Newfoundland and Labrador, Ontario and Quebec.

"This recall was triggered by findings of the CFIA during the investigation into a foodborne illness outbreak," the statement said without elaborating.

Recalled products should be thrown out or returned to the store where they were purchased, the CFIA advises. (CFIA) "The CFIA is conducting a food safety investigation, which may lead to the recall of other products," it said.

The voluntarily recalled product comes in 1.5 kg bags, bears the UPC code 8 73668 00179 1, and best before dates up to and including March 15, 2018.

Recalled products should be thrown out or returned to the store where they were purchased, CFIA advised.

Food contaminated with hepatitis A virus may not look or smell spoiled, but consumption may cause hepatitis and produce a self-limited disease that does not result in chronic infection or chronic liver disease, according to the agency.

The illness is usually mild and starts about 15 to 50 days after the contaminated food is eaten. It generally goes away by itself in a week or two, although it can last up to six months in some people.

It can cause inflammation of the liver, and symptoms may include fever, low appetite, nausea, vomiting, diarrhea, muscle aches, and jaundice — a yellowing in the whites of the eyes and the skin.
