To assist pork producers and their veterinarians in the management, control and potential elimination of porcine epidemic diarrhea (PED) virus, the National Pork Board has funded eight, six-month projects.

Updates from the researchers will be posted every two weeks at www.pork.org, according to Paul Sundberg, DVM, vice president of science and technology for the Pork Board. The final reports will also be posted online but are not intended to be the final outcome. For further information, contact the Pork Board’s Lisa Becton, DVM, at lbecton@pork.org.

The projects include:

  • Kansas State University – Study tissue localization, shedding, virus carriage, antibody response and aerosol transmission of PED virus following inoculation of feeder pigs;
  • The Ohio State University – Propagation of PED virus in tissue culture and development of standardized reference samples for use in diagnostic testing;
  • Iowa State University – Oral fluid testing for cost-effective and efficient surveillance and control of PED virus in swine for on-farm monitoring;
  • University of Minnesota – Development and validation of isolation and diagnostic testing detection for PED virus;
  • University of Minnesota – Development and validation for diagnostic testing for antigen and antibody detection for PED virus to further serologic monitoring and surveillance, and to develop and validate oral fluid testing for on-farm surveillance;
  • University of Minnesota – Environmental stability of PED virus including determining survival in fresh feces that represents the risk posed by transport; determining survival in slurry that reflects the risk of manure spreading; studying PED virus survival in drinking and recycled water used in truck washes; and studying PED virus survival in animal feed;
  • University of Minnesota – Epidemiological investigation on propensity for lateral spread of PED virus in transport vehicles at slaughter and in unrelated sites next to infected sites, and identify site-level risk factors associated with infection; and
  • Iowa State University – Evaluation of time and temperature sufficient to kill PED virus in swine feces on metal surfaces.
