Independent laboratory results have shown two agricultural disinfectants produced by Neogen Corporation are effective against Porcine Epidemic Diarrhea virus (PEDv).

The independent study showed that DC&R Disinfectant and BioSentry BioPhene Disinfectant demonstrated “complete inactivation” of the PEDv organism when tested in accordance with current “Good Laboratory Practice” protocols commonly used to evaluate disinfectants. The study’s test results meet the U.S. Environmental Protection Agency’s (EPA) criteria for a virucidal label claim. The label claim is now pending the agency’s approval.

“While the results were expected, the independent validation of the efficacy shown by our disinfectants to kill, or inactivate, the porcine epidemic diarrhea virus should further strengthen producers’ confidence in their use against the virus,” said Terri Morrical, Neogen’s vice president of Animal Safety. “It is estimated that seven million baby pigs have been lost to the virus in the United States. This validation of the effectiveness of our disinfectants comes at a critical time for the swine industry.”

PEDv can devastate a population of nursing pigs, with mortality approaching 100 percent, and can significantly impact the performance of adult pigs. The virus is not transmissible to humans and does not affect food safety. However, it is estimated the disease will cut pork production as much as 7 percent. This reduction is already becoming evident in pork prices.

The disinfectants shown to be effective against PEDv in the study are:

  • DC&R Disinfectant, EPA Reg. No. 61282-59, is a unique vapor phase disinfectant with a neutral pH that is non-corrosive.
  • BioSentry BioPhene Disinfectant, EPA Reg. No. 61282-53, is a phenolic derivative disinfectant that is effective on hard surfaces, and other areas where organic load may be an issue in and around farm premises.

PEDv was first reported in the United Kingdom in 1971, and has since been found in several other countries in Europe and Asia. Pigs infected with PEDv, which is transmitted through a fecal-oral route, via fomites in the pigs’ environment (e.g., boots, brushes, buckets, etc.), or by other methods, may show varying symptoms, including diarrhea, vomiting and dehydration. Recovery, when possible, can take a week to 10 days. For more information, contact Neogen at 859/254-1221.
