There is a system of global maximum residue limits through the Codex, through the FAO. Unfortunately, not every country recognizes that global standard, and in fact that global standard is sometimes not appropriate for each individual country because the use pattern is different.
Maximum residue limits is largely not a health or scientific process. It's really how the product is used in that individual country. So we promote a synchronous MRL process between Canada and the U.S. and our major trading partners so there are not barriers to trade. It is an unfortunate area that can sometimes creep in where there is a maximum residue limit that would create a barrier. I believe we need to look at this from a global perspective to make sure it doesn't happen.
