A property of any orally administered agricultural or veterinary chemical product (eg worming paste, rodenticide) that is a measure of the acceptability of the product by the target animal, based on its organoleptic properties such as flavour and texture. Palatability is an important property to measure, as products of low palatability will be only partially consumed, if at all.

  • Schedule 5—poisons of a hazardous nature that must be readily available to the public, but require caution in handling, storage and use. Labels of these products bear the signal heading 'Caution'.
  • Schedule 6—poisons that must be available to the public, but are of a more hazardous or poisonous nature than those classified in Schedule 5. Labels of these products bear the signal heading 'Poison'.
  • Schedule 7—poisons that require special precautions in manufacture, handling, storage or use, or special individual regulations regarding labelling or availability. Labels of these products bear the signal heading 'Dangerous poison' and may have other special labelling and restrictions on their supply, availability, possession and use.
  • Schedule 8—controlled drugs that should be available for use, but require restrictions of manufacture, supply, distribution, possession and use to reduce abuse, misuse or physical or psychological dependence.
  • Appendix B—those substance considered by the ACCS not to require control by scheduling because of their low toxicity. Inclusion in Appendix B is based on information available at the time of assessment. Labels of chemicals in Appendix B do not bear a signal heading.
