Porcine Epidemic Diarrhea virus has already been confirmed at 13 pig farms in Ontario.

That includes two cases in Perth, two in Middlesex and one in Oxford County.

It now appears the nasty and fatal illness is spreading to piglets in Manitoba.

Officials say it has surfaced at a farm in the southeastern portion of that province.

PED has killed millions of piglets in the USA.

It has no effect on humans or on the quality of local pork.
