What is a Maximum Residue Limit?

All food products grown in and imported into Canada (both organic and conventional) are tested for pesticide residue. It is important to note that Health Canada states “to date, there is no evidence to indicate that there is a health risk from eating conventionally grown produce because of pesticide residues, or that organic foods are safer to consume than conventionally produced food.”41 They must both meet the same guidelines for Maximum Residue Limit (MRL). The maximum permitted residue is set by Health Canada and enforced by the Canadian Food Inspection Agency. Maximum Residue Limits are set well below the noeffect level for humans (often 100 to 1000 times below).42 Each pesticide has its own MRL, but the default limit is 0.1 parts per million.43
