Due to recent outbreaks in livestock viruses (coronavirus PEDV), new sanitization protocols have been implemented for livestock trailers in Canada as a result of our research. These new protocols require that interior surfaces of a trailer be heated to at least 75°C for at least 20 minutes to ensure that all viruses and bacteria of concern have been inactivated. The proposed research will work with industry partners to develop a sensing system that will ensure all trailers being heated do in fact achieve the time and temperature criteria for sanitization.
