Advice for veterinarians on drug use and withholding periods in (backyard) poultry


Most of the major poultry species are defined as “major food producing species” in the NSW Stock Medicines Act 1989 and in similar legislation in other jurisdictions. This means that specific restrictions apply to drugs that can be used to treat them, and to withholding periods (WHP) that must be applied after treatment.

Topics include:

  • restrictions on poultry treatments
  • residue issues
  • single animals and permits
  • show and backyard birds
  • pesticide sprays
  • other information on maximum residue limits
  • state variation
