I'll turn to the CFIA.
Dr. Ireland, I'd like to ask you this: From the CFIA's documented cases and from all of the experiences that members of your organization have with respect to farms, what is the greatest source of risk for transmission of disease on farms?
Many of us are wondering whether this bill is a solution in search of a problem. We've heard that there's not a strong evidential link between activists' being on farms and transmitting disease.
Can you inform the committee, from the CFIA's perspective, of the greatest risk in transmission of diseases on farms?
