Contaminants

Our contaminant testing involves the use of advanced and modern testing equipment to develop methods and carry out testing for current and emerging contaminants of interest to global regulators and customers of Australasian dairy products.

Current routine methods

  •  Aflatoxin M1, Glyphosate, Chlorate & Perchlorate, Melamine & DCD
  • Detergent and sanitiser residues arising from cleaning on-farm and in manufacturing plants.
  • Heavy metals

Rapid response to incidents

Our unique combination of capability to carry out rapid method development, and bring this into high throughput operations, enables us to work with MilktestNZ to quickly provide solutions to potential contamination issues.  Our testing in support of the 2015/16 1080 monofluoroacetate contamination threat is an example of this in action.

Emerging contaminants

Analytica and MilktestNZ develop methods for testing emerging contaminants in milk and dairy products, and implementing them in operations that are designed to meet industry requirements for cost and capacity.  These developments are generally market or customer driven, and we welcome enquiry about any current or future dairy contaminant where our capability may be able to assist.
