The sealing at the border is one of the things I had wondered about from the previous testimony. Let's say somebody drops off some pigs at one of the stations in the States. Maybe the trailer is used to shuttle some pigs between other operations, which we would never know about, and could be contaminated in some different ways, with different diseases. However, at some point we need to seal those trailers.
Should they be sealed at drop off, or should they be sealed at the border?
