It’s a welcome alternative to intensive and meticulous washing and disinfecting that has been the approach for cleaning trucks returning from the United States where Porcine Epidemic Diarrhea virus is widespread.
Dr Terry Fonstad, a professor in the College of Engineering at the University of Saskatchewan, says researchers with VIDO-Intervac have demonstrated that heat is extremely effective in destroying pathogens.
The researchers have given truckers temperature and heat regimes that range from high temperatures for low time frames to a little bit lower temperatures for longer time frames that can be used to develop heating systems for the transport industry that will ensure they have proper pathogen kill under varying conditions from varying heating systems.
For example, 15 minutes at 75 degrees is effective.
At 80 degrees it takes slightly less time.
Dr Fonstad says input from an industry based advisory team has been a key factor in the success of this effort.
