People in the potato sector have questions regarding chlorpropham's maximum residue limit (MRL). In the EU, it has been decided that this pesticide is no longer approved for use in the storage of potatoes. Chlorpropham was widely used in storage sheds in recent decades. There is, therefore, a chance of the cross-contamination of potatoes being stored in warehouses were chlorpropham was previously used.
An MRL of 10 mg/kg currently applies. In Europe, there is a procedure for adjusting the MRL of certain potatoes. These are those that have come into contact with residual chlorpropham via storage. There is a reason for establishing such a low MRL level. It is hoped that the illegal use of this substance can be prevented. This, in turn, guarantees consumer protection.
The MRL is, however, high enough to ensure that existing warehouse space can still be used. The European Food Safety Authority will advise the European Commission on a temporary MRL for the coming years. A decision about this is expected sometime in 2020. Until then, the existing MRL (10 mg/kg) remains in force.
