Under the authority of Health of Animals Act and the regulations, the Canadian border services officers are the first line who are actually trained. They have been given all the tools to visually inspect those trailers that are coming in.
They have to be visually clean. The definition of visually clean also means that there is no dung, dirt, or any organic material, either hanging out or dripping. Also, during the winter months, for example, scraping it clearly clean and making sure that there has been disinfection or washing done would be very visible. They are, in a way, our designated inspection staff at the border and they make sure that these trucks are coming back clean.
Should there be any situation where the trucks are not clean or trailers are not disinfected according to their judgment, they can either refer to CFIA, and CFIA will show up and actually have that evaluation, or they can turn the trailer back so it can get cleaned before returning.
