Let's say a truck driver is bringing in foodstuffs, animals, vegetables, or maybe ingredients for dog and cat food, which we had a problem with lately. He has a sense there's something wrong with his cargo and it has been contaminated--it smells funny, or something like that. I think he should be required to report this ahead of time so there is somebody at the border who can decide whether or not to let the material in.
