Eurofins New Zealand pesticide division is IANZ Accredited and has the largest testing scope available with over 550 compounds

Pesticides are chemicals used in agriculture to protect crops against insects, fungi, weeds and other pests. In addition to their use in agriculture, pesticides are also used to protect public health in controlling the vectors of tropical diseases, such as mosquitoes.

But pesticides are also potentially toxic to humans. Pesticide residue refers to the pesticides that may remain on or in food after pesticide formulations are applied to food crops. The levels of these residues in foods are often stipulated by regulatory bodies in many countries.

New Zealand Ministry for Primary Industries (MPI), Codex, and other Regulatory Body’s Maximum Residue Limits (MRLs) are based on Good Agricultural Practice data and foods derived from commodities that comply with the respective Codex, or other Regulatory Body, MRLs are intended to be toxicologically acceptable.

The analytical testing of food products is defined by international convention, published in a document called the Codex Alimentarius. This is published by the Food and Agriculture Organisation of the United Nations World Health Organisation. This 183 page document has been summarised in the table below which represents the food matrices that Eurofins is able to test:
