Laboratory testing for dairy
Dairy products are tested in laboratories that are specifically recognised for this work.
Dairy products are tested to prove they conform with:
- New Zealand minimum food safety requirements
- Overseas Market Access Requirements (OMARs).
To be recognised to do the testing, dairy laboratories need to meet the requirements of a recognised laboratory programme (RLP), as set out in the Animal Products Notice: Specifications for Laboratories.

Dairy laboratory categories
Dairy laboratories are divided into 2 categories, with different testing for each category. Testing must be carried out in a laboratory recognised in the appropriate category for the required test.
Category 1 laboratories
These test dairy products and material intended for domestic and export markets. They're recognised by MPI for testing to demonstrate that the product:
- is fit for purpose, including food safety, wholesomeness and standard of identity or truth of labelling
- meets specific requirements for overseas market access.
Category 2 laboratories
These are recognised dairy laboratories that belong to an animal product business. They test the business’s dairy material, including raw milk, intended for the domestic market. They're recognised by MPI to carry out testing which demonstrates that the product:
- is fit for purpose for sale in New Zealand, including food safety, wholesomeness and standard of identity or truth of labelling
- meets requirements set out in the company’s risk management programme (RMP) for internal quality control and good operating practice (GOP).
