Paris | Reuters — Mexico reported outbreaks of porcine epidemic diarrhea virus (PEDv) in 17 states out of 19 tested, the World Animal Health Organization (OIE) said.
Following reports of unusually high mortality, mainly in piglets, in the central-western part of the country, Mexican veterinary officials tested 2,309 samples between August 2013 and May 2014 in farms and slaughterhouses, the Mexican agriculture ministry told the OIE.
These showed that 30 per cent were positive for PED, suggesting there may be some other causative agent involved in this event, the ministry said.
