Technology raises US residue detection
The detection of pesticide residues in the US state of California is being raised by the use of new technology. The California EPA’s Department of Pesticide Regulation (DPR) carried out dual testing of 449 food samples using liquid chromatography mass spectrometry (LCMS) and the older multi-residue testing last year. It found that 86% of samples contained detectable residues but 78% contained residues that were only detected by the LCMS screen. The vast majority (97.1%) of residues detected by LCMS were within legal limits, with only 2.9% being illegal.
