Key points

  • In 2018–19, the overall compliance with Australian standards was 99.48 percent for aquaculture samples and 100 percent for wild-caught samples.
  • Australian seafood producers continue to demonstrate a high degree of good catching, growing and processing practice.
  • The National Residue Survey is certified to ISO 9001 Quality Management System.

The National Residue Survey (NRS) is an operational unit within the Australian Government Department of Agriculture, and since 1992 has been funded by industries through levies or direct contracts.

The NRS is an essential part of Australia’s pesticide and veterinary medicine residue management framework providing verification of good agricultural practice in support of chemical control-of-use legislation and guidelines.

NRS programs monitor the levels of, and associated risks from, pesticides and veterinary medicine residues and contaminants in Australian food products. The programs help to facilitate and encourage ongoing access to domestic and export markets. NRS supports Australia’s primary producers and food processors who provide quality animal, grain and horticulture products which meet both Australian and relevant international standards.

Seafood program overview

The seafood program has been operating since the early 1990s and is funded through industry cost recovery arrangements. The program involves the testing of Australian aquaculture and wild-caught seafood products for a range of pesticides, veterinary medicines and environmental contaminants.

The program ensures seafood exports satisfy Australian export certification and importing country requirements. In addition, the program supports industry quality assurance initiatives and enables domestic seafood processing facilities to satisfy state and territory government regulatory authority licensing requirements.

Sample collection

The number of samples collected is based on Australian production levels and/or overseas export market requirements.

Samples are collected by government approved officers who obtain a random selection of samples at specified times from aquaculture farms or processing establishments.

Analytical screens

Analytical screens are developed in consultation with the industry and take into account Australian registered chemicals, chemical residue profiles and overseas market requirements.

Seafood samples are screened for a range of pesticides, veterinary drugs and environmental contaminants, as shown in Table 1.

Table 1. Analytical screens for the seafood program
Analytical screen Chemical group Analytes
Veterinary drugs and pesticides Anthelmintics includes macrocyclic lactones
Antimicrobials includes aminoglycosides, beta lactams, macrolides, nitrofurans, nitroimidazoles, phenicols, sulfonamides, tetracyclines and quinolones
Hormones includes stilbenes and androgenic steroids
Environmental contaminants Organochlorines aldrin, chlordane, dieldrin, DDT, endrin, HCB, HCH, heptachlor, lindane, mirex, toxaphene and PCBs
Metals antimony, arsenic, cadmium, chromium, lead and mercury
Dyes crystal violet, malachite green, brilliant green, methylene blue and Victoria blue


In 2018–19, a total of 191 aquaculture and 100 wild caught seafood samples were collected for analysis. The results were compared with the Australian standards and where appropriate, relevant international standards.

A summary of seafood compliance with Australian standards over the past six years is provided in Table 2. The results highlight excellent compliance with Australian standards and demonstrate the strong commitment of the seafood industry to good catching, growing and processing practice. The consistently high compliance rates help maintain the reputation and integrity of Australian seafood in domestic and international markets.

The yearly summary datasets for the seafood program are located on the department’s website.

Laboratory selection and performance

The NRS contracts laboratories to analyse animal and plant product samples for pesticide/veterinary medicine residues and environmental contaminants.

Laboratories are selected through the Australian Government tendering process on the basis of their proficiency and value for money. Laboratories must be accredited to international standard ISO/IEC 17025 at commencement of testing.

Contracted laboratories are proficiency tested by the NRS to ensure the validity of their analytical results and technical competence.

The NRS has been accredited by the National Association of Testing Authorities as a proficiency test provider since July 2005.

International export markets

The NRS maintains a database of maximum residue limits (MRLs) established for Australia and major export markets for industries supported by the NRS. All analysis results are checked for compliance with Australian standards and relevant international MRLs.
