Department of Primary Industry and Fisheries 74 During 2000/2001, 104 samples were collected from NT stock, primarily through abattoirs. There were 68 cattle, 10 buffalo and 10 camel samples analysed with no detection greater than the MRL/MPC from an NT property. There were no detections of antimicrobials, organochlorines or organophosphates. Beef organochlorines, organophosphates and synthetic pyrethroids The main issue for the NT continues to be the interval between the last treatment with cattle tick and buffalo fly treatments and slaughter to satisfy the MRL in both domestic and export markets. Advice was provided to all producers in the cattle tick and buffalo fly area on the residue risk and control of cattle tick and buffalo fly. HGPs Many markets, both domestic and export, are sensitive to cattle products derived from animals implanted with HGPs. A national program to comply with European Union (EU) import requirements was developed in 1993 which satisfied EU reviewers. This program comprised two components, controls on the use of HGPs in the cattle industry, and systems for the recognition of stock which have not been implanted with HGPs. Controls on HGP usage are underpinned by the Control of Hormonal Growth Promotants (Stock Act) (Northern Territory). Two properties are audited for compliance each year. A register of HGP users is maintained in the NT as a requirement of the national HGP control system. In the NT, 76 properties purchased 254,450 doses of HGPs last year, twice as much as in the previous year. On 1 December 1999, a new national system for declaration of HGP freedom began which was designed for accrediting properties wishing to specifically supply the EU market. Accredited properties are only to hold cattle not implanted with HGPs, hold appropriate documentation, and adopt the national livestock identification scheme (NLIS). Accredited properties may only purchase cattle from accredited properties and must notify the NLIS database of the individual identification of any stock sold outside the system. This component is now covered under the Federal Export Control Act but is administered by State authorities. There is currently only one NT property that is EU accredited. However many others are interested. The NLIS describes the use of permanent devices containing electronic transponders from which individual identification can be read electronically. Approved devices may be rumen pellets or eartags applied at weaning which then will remain with that animal for life. Three audits were completed during the year as required under the national HGPs audit program (two users, one EU accredited property). The NRS reimburses the States for this activity at $380/audit. During the year, use of pink tags with the logotype "HGP Free" was allowed to be used as transaction devices to declare cattle HGP free, but were no longer accepted for the purposes of the EU market. Industry requested this system to remain for the purposes of other markets such as Saudi Arabia. AQIS now uses the pink tag together with the appropriately endorsed national vendor declaration as the basis for the non-EU HGP free certification system. NARM NARM is a national program to monitor antibiotic and antibacterial contaminants. The national program is now targeted to high-risk areas, which excludes the NT. Another initiative by AFFA is the targeted antibiotic residue testing program (TART). This allows AQIS officers in abattoirs to select high-risk animals for sampling for antibiotic residues.
