2024-2025 National Residue Survey

The macadamia residue monitoring program, which began in 1996, tests Australian macadamias for a range of chemical residues and environmental contaminants to ensure our industry meets quality assurance and market access requirements at home and internationally.

Assurance for domestic and international customers 

Australia has long upheld a reputation for its clean and green food production standards, and it is something our industry takes extremely seriously.

An operational unit within the Australian Government Department of Agriculture and Water Resources, the NRS tests Australian macadamias for a range of chemical residues and environmental contaminants, ensuring the macadamia industry is meeting the quality assurance and food standard requirements for both domestic and international markets.

The NRS keeps a database of maximum residue limits for those countries that represent major export markets for Australian plant and animal products. As stated in the official report, these results “highlight excellent compliance with Australian standards and demonstrate the strong commitment of the macadamia industry to good agricultural practices."
