What is the role of the Poisons Standard in Australian food law?

The Australia New Zealand Food Standards Code does not make any reference to the Poisons Standard. Nevertheless, it is often useful to consider the Poisons Standard in developing or updating the formulation for a new or existing product. This article explains how the Poisons Standard interacts with Australian food laws and what it means if a substance is listed in the Poisons Standard, and highlights some important case studies where a failure to consider the Poisons Standard could result in a product formulation that does not meet regulatory requirements.
