Health officials in Saskatchewan say a case of E. coli sickness is linked to a national frozen hamburger recall.

Frozen burgers were pulled from store freezers in Ontario, Manitoba, Alberta, British Columbia, Saskatchewan and the Northwest Territories following the Feb. 19 recall.

They were sold at Safeway under the names of Gourmet Meat Shoppe and Butcher's Cut.

Someone in the Regina area came down with an E. coli infection but is now recovering, the government said in a news release.

It's believed the person ate the burger before the recall was issued, the government said. No details about the case were provided.

The health ministry says symptoms of E. coli infection, including headaches, diarrhea and abdominal pain, usually appear within three to four days but can occur up to 10 days later and last five to 10 days.

People who have the burgers, which are dated "Best before August 14, 2013", are advised to return them to Safeway or throw them out.
