National Residue Control Plan (NRCP) is a statutory requirement for export to EU countries. Under NRCP, definite sampling schedule and sampling strategies are drawn every year for monitoring the residues of substances like Antibacterial/Veterinary Medicinal Products and environmental contaminants. Samples are collected from hatcheries, feed mills, aquaculture farms and located in maritime states and tested for the presence of any residue/contaminant of the following substances:


Group A – substances:

Substance group Substances Substance monitored
A1c Steroids Progesterone
MedroxyProgestrone (acetate)
17-β Oestradiol

Following are the other residue monitoring/control programmes undertaken by MPEDA QC Laboratories:

  1. Monitoring of Pesticide Residues at National Level (MPRNL):- This is an ongoing project funded by Dept. of Agriculture (MoA). The samples of inland fishes, crustaceans, and Molluscans collected from all the maritime states are analyzed for organo-chlorine pesticide residues by MPEDA QC Laboratory in Kochi.
  2. Monitoring of radio nuclides:- The wild-caught Fishes, Shrimps and Cephalopods samples are collected from different regions and forwarded to BARC, Mumbai, for the analysis of radio nuclides.
