National Residue Survey Macadamia

Another perfect score for Australian macadamia industry in 2022-2023 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.

The results for 2022-2023 are just in and confirm the industry’s excellent compliance with Australian standards. Since the survey began the industry has recorded an unbroken record of 100% compliance, underlining the commitment of the industry in Australia to good agricultural practices.

As the world’s leading supplier of macadamias, Australia has an unwavering commitment to food safety and upholding the premium quality standards that have made our macadamias the best in the world. The NRS provides quantifiable proof of our dedication to reliable and sustainable farming with a preference for non-chemical pest and disease controls whenever possible.  

Pristine record continues

Our industry has achieved 100% compliance every year since the voluntary program’s inception in 1996, and these consistently outstanding results are the product of the skill and commitment of our growers, coupled with their world-class in-crop and post-harvest practices. 

It’s a record we are extremely proud of and one that has not been matched by any other Australian fresh product.

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 Australia’s excellent compliance status against Australian standards and helps maintain the reputation and integrity of Australian macadamia nuts in international and domestic markets."
