Monitoring of pesticides and veterinary drugs in Australian cattle: verification of the residue control system

Abstract

The Australian National Residue Survey in partnership with the Australian Quarantine and Inspection Service and industry routinely monitors beef to ensure that regulatory requirements for residues are being met. In the 10-year period from 1997 to 2006 a total of 128,902 samples were subjected to residue testing covering veterinary drugs and veterinary and agricultural pesticides in a random monitoring program. Residues of agricultural and veterinary chemicals exceeded the Australian standard in 13 and 7 samples, respectively. Greater than 99% of samples did not contain detectable residues above the Australian standard while greater than 90% of samples did not contain any residues of compounds included in the survey. The results of the surveys provide verification that the Australian residue control system is appropriate and that the requirements of countries importing Australian meat products can be satisfied. The surveys have also demonstrated that industry based programs and state based regulatory controls over sites contaminated with organochlorine residues are effective in managing residues of these chemicals in cattle.
