Defining vertebrate toxic agents

Find out about the legal definition of vertebrate toxic agents.


What is a vertebrate toxic agent?

Vertebrate toxic agents (VTAs) are a subset of agricultural compounds under the Agricultural Compounds and Veterinary Medicines (ACVM) Act 1997 (see definition below).

VTAs are trade name products used to kill, control, or limit the viability of vertebrate pests such as rabbits and possums. The definition of VTA includes products that have a negative effect on reproduction, but it does not include attractant or repellent substances that are not toxic.

If you are unsure of your product’s status under the ACVM Act, we can do a class determination for you. There is a fee for this service.
