Fourth Canadian farm hit by pig killing virus: Ontario official

(Reuters) – The piglet killing Porcine Epidemic Diarrhea virus has spread to a fourth farm in the Canadian province of Ontario, the provincial government said on Wednesday, despite the hog industry’s efforts to stop it by disinfecting delivery trucks and clothing used on farms. The virus has killed more than 1 million piglets in the United States but it has so far been contained within Canada to southern Ontario farms. The fourth case has been confirmed in Norfolk County along the north shore of Lake Erie, said Mark Cripps, a spokesman for Ontario Premier Kathleen Wynne. Ontario confirmed the first Canadian case last week.
