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 processing plants, located in maritime states and tested for the presence of any residue/contaminant of the following substances:

Group A – Substances having an anabolic effect and unauthorized substances:

Sl. No.Substances/GroupParameters
1Stilbenes (A1)

Diethyl Stilbestrol



2Steroids (A3)

17-Beta Estradiol,

Progesterone &

Medroxy Progesterone acetate

3Compounds included in Annex IV to Council Regulation (EEC) No 2377/90 (A6)


Nitrofurans (4) & their metabolites (4)

Nitroimidazoles (7)

Group B Substances – Veterinary drugs and Environmental contaminants:

Sl. No.Substances/GroupParameters
1Antibacterial substances (B1)

Tetracyclines with 4-Epimers (3)

Sulphonomides (11)

Quinolones/Fluro-quinolones (9)

Macrolides (4)

Beta Lactams (6)




Cephalosporins (2)

2Anthelmintics (B2a)



3Organochlorine compounds including PCBs (B3a)

DDT, BHC Isomers, Aldrin, Dieldrin, Heptachlor, Chlordane, Endrine, HCB.

Poly-chlorinated By-phenyls (PCBs)

4Chemical Elements (B3c)Mercury(Hg), Cadmium(Cd), Arsenic(As) & Lead(Pb)
5Mycotoxins (B3d)Aflatoxin B1 & B2
6Dyes (B3e)

Malachite green & Leuco-malachite green

Crystal violet & Leuco-crystal violet

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.
