For example, maximum residue levels are established at the Codex Alimentarius for most, not all, food in the world. We follow them or we have our own maximum residue levels. Because of the science, we've done a risk assessment. They could differ but they would be similar.
If we have a standard in Canada—I'll use 0.1 as an example—the product that's coming into Canada has to meet that standard, whether it's 0.1 parts per million or parts per billion. If it's greater than that, it would not be allowed into Canada. The CFIA, working with the pest management regulatory agency of Health Canada, does regular monitoring of imported products all the time. If contraventions of products are coming in, they get on a watch list, and then 100% of the next shipments are checked to make sure they're respecting the residue level in Canada.
Is there a possibility that a product will come into Canada with a residue higher than what's in Canada? Yes, but that's why we have the monitoring program and we work with certain countries. If it continues, that product would be banned from Canada and a watch list for it would be put on at the border.
