I am not in a position to either confirm or denounce this theory.
At this point, I am going to trust the research that USDA and the OIE has trusted and not the "POLITICALLY MOTIVATED" theories to the contrary that have not been proven.
Unfortunately, those who want to keep the Canadian border closed to live cattle will sink their teeth into any unproven theory that contradicts the OIE and USDA's research.
