When it comes to preventing the spread of PEDV, strict biosecurity must extend beyond the farm gate—and go all the way to the packing plant. Some new data from research funded by the Pork Checkoff, the National Pork Producers Council and the American Association of Swine Veterinarians, makes this clear as it shows that PEDV can be spread by contamination during transport of pigs to markets.
The objective of the study was to assess the risk that pig-collection points such as packing plants have in promoting an initial outbreak of a novel disease organism such as PEDV in the United States. To do this, researchers estimated the rate of contamination of trailers with PEDV during the unloading process. They collected samples pre- and post-delivery from 669 livestock trailers at seven packing plants.
Specifically, the study found that:
- 17% of trailers were contaminated with PEDV before unloading the pigs
- 11% of trailers that were not contaminated with PEDV on arrival were subsequently contaminated during unloading
PEDV was confirmed for the first time in U.S. swine herds in mid-May.The most recently available report indicates there are 378 confirmed cases of PEDV in 15 states, with most of those in Iowa and Oklahoma.* (See most recent states/cases by clicking here and then on Number of New Cases Reported).
