I mentioned briefly, earlier, that the agency has a residue monitoring program. Canada uses some pesticides that the U.S. doesn't use and vice versa. Our residue monitoring program targets a broad variety of pesticides. In some cases we find pesticides that are not approved and are not allowed in Canada, and if such is the case and if the maximum residue limit is exceeded, that product is not allowed entry.
Obviously, we're not testing everything, but we have a monitoring program that plans the risk, looks at the product, and makes a decision on the basis of what is acceptable or not.
