On May 2, a top official with the Canadian Food Inspection Agency announced that a farm worker with swine flu who had travelled to Mexico was thought to have infected about 200 pigs in Alberta — the first such reported case in the world.

The WHO has ruled out any risk of infection from consuming pork. Swine flu — like all influenza viruses — is not a food-borne illness. |
