The Public Health Agency of Canada has confirmed an additional seven illnesses due to E. coli bacteria have been linked by investigators to B.C. cheese products that were recalled last week.

An outbreak of bacteria at Gort's Gouda Cheese Farm in Salmon Arm, B.C., has been blamed for an elderly B.C. woman's death and a rash of illnesses across other provinces since the beginning of July.

Most of those who became ill began displaying symptoms in late August and September, and the number of cases under investigation now totals 21.

Since Saturday, another five cases in B.C. have been added to the list of illnesses under investigation, along with another case in Alberta and one case in Manitoba.

Gort's Gouda Cheese - Mild Gouda - recall notice

The Public Health Agency of Canada said in a recent alert about the recall that the symptoms of an E. coli infection "mainly involve the gut" and can include severe stomach cramps, diarrhea, vomiting and fever over the course of five to 10 days.

Around five to 10 per cent of those who become ill due to E. coli develop kidney complications that can include acute renal failure, which is sometimes fatal. Young children and the elderly are at the greatest risk of developing complications involving the kidneys, the agency says.

On Sept. 17 and 19, The Canadian Food Inspection Agency (CFIA) and Gort's Gouda Cheese Farm initiated a recall of 15 raw-milk cheese products that were sold either online, at the Gort's farm, or elsewhere in B.C. and Alberta between May 27 and Sept. 14.

One of the co-owners of Gort's Gouda Cheese Farm in Salmon Arm has offered a tearful apology, saying the company is trying to get to the source of the E. coli outbreak.
