MINNEAPOLIS, Minn. – Researchers at the Univ. of Minnesota College of Veterinary Medicine developed a second diagnostic test for porcine epidemic diarrhea virus (PEDv). This is the second test PEDv test developed by the university's researchers. Researchers at the college already developed a test to detect the presence of the virus.

The new diagnostic test will enable hog producers to identify which pigs have been exposed to the virus, even if the animals have not shown symptoms of PEDv. The university will make the test, called an enzyme-linked immunosorbent assay (ELISA), available to the industry through the university's Veterinary Diagnostic Laboratory. The cost is less than $15 per serum sample.

“The disease has already affected several hundred farms in Minnesota,” said David Preisler, executive director of the Minnesota Pork Board. “This test is very important because accurate, fast diagnostics are the best starting point to give veterinarians the best information to work with their farmer clients. This new test is a great next step in helping farmers manage this disease.”

The American Association of Swine Veterinarians put the total number of confirmed cases since the start of the outbreak at 2,962. So far, 23 states and Canada have reported having at least one confirmed case.

The Minnesota Rapid Agricultural Response Fund, National Pork Board and Zoetis Inc. provided funding for the research.
