Pesticide residues in food in Switzerland.

Every year, official Swiss laboratories are involved in the analysis of about 8000 food commodities in the context of pesticide residue surveys. Between 90 to 100 different active ingredients are found normally in total foodstuffs analysed and more than 6% of the investigated samples have a contamination level exceeding the federal tolerance limits. No real improvement in what concerns the quality of food with respect to pesticide contamination has been observed these last years.
