Residues in Plant Foods

Feldversuch Rückstände PSM

PPP residues on foods must not have any health effects for consumers. In addition, they must not be higher than what is necessary for “good agricultural practice”. Both of these factors are considered for PPP approval. Residue level is substantially influenced by agricultural use. The manner of application, the quantity applied and the time elapsed between application and harvest (the so-called ‘waiting period’) are important factors here. Agroscope experts assess the residues to be expected in plant foods based on residue trials submitted by the companies with their approval dossier. Based on these data, it is checked whether the maximum residue levels (MRLs) valid in Switzerland are being complied with, or new MRLs are derived and their determination requested.
