Contamination of organic cereals with phosphine

The aim of this project is to show the current situation of the sources and causes of contamination of phosphine in organic cereals in Switzerland.

Along the supply chain, it should be determined where phosphine contamination in organic cereals could come from and whether it could be avoided. With the help of the current state, measures to reduce phosphine residues are to be developed and at the same time, the limits of contamination prevention are to be pointed out. If it turns out that phosphine residues at a certain level are technically unavoidable, the results of the study should serve as a basis for the discussion of the intervention level.
