Western Australian beef producers faced a major crisis in 1987 because of organochlorine pesticide residues in some Australian beef cattle. We had to react quickly to find the sources of these residues and to keep contaminated cattle out of our abattoirs. Trace-backs led to 269 Western Australian properties in quarantine by the end of 1987. About 85 per cent of quarantined properties had cattle contaminated with pesticide residues from 'broadacre' sources, especially from potato and other horticultural crops. Another 10 per cent of properties were in quarantine because of contamination from basal treatment of timber power poles
