Management of organochlorine and related residues


Management of persistent chemicals in soil is an important issue for modern-day graziers. It is one of the key points addressed by livestock industry quality assurance programs such as Livestock Production Assurance (LPA), LPA QA (including Cattlecare and Flockcare) and the National Feedlot Accreditation Scheme (NFAS).

For example, the LPA QA Code of Practice requires accredited producers to: identify any part of the property that may be contaminated by persistent chemicals; manage those areas to prevent stock being exposed to contamination; and identify and manage any stock exposed to contamination.

Topics include:

  • organochlorine
  • polychlorinated biphenyls
  • endosulfan
  • maximum residue limits
  • fluctuations in cattle OC residue levels
  • property risk management process
  • assess the risk of OC residues
  • manage contaminated sites
  • feedlot and feeding sites
  • other OC residue sources
