FSSAI’s Contaminants, Toxins and Residues Regulations set a maximum residue limit (MRL) for each approved pesticide on each crop. A pesticide that is not approved for a crop must not be present above the default limit of quantification, which is where most failures happen: a farmer sprays a chemical approved for a different crop, and the residue becomes a violation.
Multi-residue methods based on QuEChERS extraction with LC-MS/MS and GC-MS/MS screen hundreds of pesticides in one run. Export lots are compared against the importing country’s MRLs, which in the EU are often far lower than India’s. Some pesticides, such as glyphosate, dithiocarbamates and fumigants, need separate single-residue methods.
