Research being conducted in Vietnam by the University of Nebraska is demonstrating the value of baking swine transport trailers to help prevent the spread of African Swine Fever. Researchers with the University of Nebraska have investigated if it’s possible to effectively inactivate African Swine Fever virus in the presence of organic materials through the use of thermal-assisted drying and decontamination which commonly operates at temperatures between 63 and 71 degrees Celsius. Dr. Paul Sundberg, the Executive Director of the Swine Health Information Center, says the use of baking has become increasingly common.

Clip-Dr. Paul Sundberg-Swine Health Information Center:
In partnership with the University of Nebraska at Lincoln and their contacts in Vietnam we’re testing that procedure in Vietnam real time.
We don’t yet have all of the reports in but we do know that there are different things that we’ve been testing and some of them are very effective. For example one of the things we wanted to do was test simple baking versus having to wash, test washing-rinsing versus not rinsing at all or high powered washing and then high powered washing and disinfection. All of those things have been tested in the laboratories and being applied in the field in Vietnam but we have laboratory reports that tell us that even just the simple washing and then baking the materials will help disinfect ASF. We add simple washing, you might want to add high powered washing and then adding on disinfecting after that, it leads to even more assurances that we’re going to make sure that our conveyances, out trailers, will not be infected or contaminated with African Swine Fever should it get to North America.

Dr. Sundberg says we know that the temperature normally used will help disinfect African Swine Fever so the results are not surprising but it’s important to have some science behind what is being done.
