A new paper from Iowa State University offers pork producers first-time insights on how various disinfectants and disinfection techniques work while also verifying existing knowledge about ways to battle Porcine Epidemic Diarrhea Virus, the Pork Checkoff says.
The four-study summary provides details of how individual aspects of trailer sanitation programs were evaluated, including thermo-assisted drying and decontamination systems, along with multiple disinfectants.
The research, led by Drs. Derald Holtkamp and Paul Thomas, identified disinfectants that may work well against PEDV even when feces is present.
The study also verified previous methods of combatting the virus. Specifically, PEDV in the presence of feces was inactivated by heating to 160°F (71°C) for 10 minutes or by maintaining room temperature at 68°F (20°C) for at least 7 days.
No other combinations of time and temperature evaluated were shown to be effective at inactivating PEDV.
