Canadian studies suggest no link between feed and PEDv

The Canadian Food Inspection Agency (CFIA) announced on Monday that it could not confirm a link between hog feeds containing blood plasma and PEDv cases in Canada.

These feed-testing results have been shared by the American Association of Swine Veterinarians and other U.S. swine organizations.

The Canadian study results are among the first insights to virus contamination in feed, as researchers there and in the U.S. work to understand how the virus has spread across the country and beyond northern borders.

Canadian feeds that included ingredients produced in the U.S., specifically commonly-used porcine blood plasma, were tested for contamination. Researchers began examining a variety of hog feed suppliers after determining feed ingredients from the U.S. likely contained PEDv.

The CFIA said imported U.S. porcine blood plasma tested positive for the virus, but studies could not prove that the contaminated pellets were capable of infecting hogs. The agency said it would continue to analyze swine feed and ingredients.

In the U.S., the number of confirmed PEDv cases continues to climb. The last weekly summary report produced by the USDA and National Animal Health Laboratory Network showed 4,106 cases of PEDv have been confirmed throughout the country.

This week, North Dakota became the 26th state to have identified cases of the hog virus.

In Missouri, the number of confirmed PEDv cases has slowly risen, now at 59. Positive tests have reached past 1,400 cases in Iowa, the worst hit state. Surrounding states vary between nearly 200 and 300 confirmed virus cases.

With fair season approaching, the National Pork Board is encouraging swine exhibitors and purchasers to be strict with biosecurity measures. Farmers are encouraged to assess their pigs' health daily, report health issues to a veterinarian (or if showing, to any exhibition organizer), avoid manure contamination between pigs and farms, and isolate new pigs or those returning to the farm.
