National Chemical Residues Programme for non-dairy animal products

The National Chemical Residues Programme (NCRP) monitors animals and animal products to confirm residue and contaminant levels meet acceptable standards. 

What is the National Chemical Residues Programme?

The NCRP is a risk-based sampling and testing programme. It monitors chemical residue and contaminant levels in animals and non-dairy animal products, including:

  • farmed animals, such as cattle, deer, goats, pigs, and sheep
  • wild animals
  • poultry
  • honey
  • fish.

The programme ensures New Zealand animal products are not a risk to health and are suitable for export.

How does the NCRP work?

The NCRP has two parts: monitoring and surveillance.


Samples are taken from randomly selected live and slaughtered animals. Sample types depend on the chemicals being tested.


Surveillance takes targeted samples from live and slaughtered animals where a risk has been found. The risk could be to human or animal health, or a risk to trade.

All samples are tested at recognised laboratories with ISO/IEC 17025 accreditation. The NCRP scope is described in New Zealand legislation.

What the NCRP tests

The NCRP tests for a broad range of chemicals, including:

  • agricultural compounds and veterinary medicines
  • certain environmental contaminants.

The programme tests for chemicals:

  • likely to be found in samples
  • of interest overseas, even if they are unlikely to be found in New Zealand.

NCRP results

Reports with results are published each year. These have more information about how sampling and testing is carried out, and recent results.
