We certainly do have an annual residue monitoring plan. Residues can be chemical, they can be biological hazards, they can be direct tampering, and they can be physical hazards as well. That program is published on an annual basis on our website.
In addition to our scheduled frequency of testing, we do random and unannounced testing of products entering into Canada, in conjunction with the importers of those products before they enter the marketplace, and we have programming that also tests product in the marketplace to a single standard, whether it's domestically produced or imported.
