Certainly.
For MRLs, as I indicated in my opening remarks, the PMRA does set, under the Pest Control Products Act, the maximum amount of pesticide residues that can legally be allowed to be found on a food commodity. We recognize too, though, that because Canada sets these MRLs, as do other countries around the world, if we have a different numerical standard than some of these other countries, there can be issues in terms of the movement of food commodities between countries.
We have been doing quite a bit of work with, for example, Agriculture Canada. We've been doing some work with them to try to understand whether or not where, when, how, and if these MRLs are causing potential trade barriers around the world. This can have an impact for market access for some of Canada's exports, for some Canadian agricultural producers trying to export their commodities to other markets around the world, which is hugely important for them. As you know, it's truly a global marketplace now.
What we've tried to do is provide our scientific expertise on the nature of these maximum residue levels, the nature of the data, information, and science that Canada has behind setting its standard, and to help share that information with other countries that may have different data, or information, or a food safety standard-setting process, so that we can align how we set these standards with other countries and try to resolve some of these differences.
Very often, the differences in these maximum residue levels between countries are actually very small, and they don't represent any kind of true safety difference between countries. A lot of the time, these are simply irritants because they're small differences. To be honest, sometimes some countries try to exploit those small differences to create these trade barriers or maybe to create a business risk that there might be a trade issue if commodity X is exported to another country. We've been providing a lot of scientific expertise, both to agriculture and through our other network of contacts in OECD countries, as well as the Codex forum on food safety standards, to try to help alleviate some of these trade barriers that truly aren't necessary.
