People are being told not to eat King James brand blue Stilton cheese because it may be contaminated with listeria.

The cheese was sold in B.C., Ontario, Quebec and Newfoundland, however the Canadian Food Inspection Agency says it may have been distributed nationally. It may have been sold at deli counters between April 14 and May 19.

There have been no cases of illness reported.

Tree of Life Canada imported the cheese from England.
