New laws pertaining to the use of some animal health products are coming into effect later this year.

In September 2024 the APMVA changed, and in some instances, cancelled registrations for products containing the active ingredient diazinon. As a result of new and continuing research, this decision is based on both trade concerns, and environmental, human and animal safety.

Diazinon is one of a group of chemicals called organophosphates, which act by disrupting the nervous system of insect pests. Over the years, diazinon’s use has been largely replaced by other products, but its role in some circumstances, particularly in farm animals, has continued to be important.

Lice, fly-strike and buffalo fly are major problems for sheep, pigs and cattle. Diazinon has played an important role in relieving the stress and damage done by pests via its presence in some sprays, powders and ear-tags.

As of September 2024, it has been illegal to buy these products and from September 2025, it will be an offence to own, store or use these them. The changes relate to diazinon only, and not to other organophosphates.

It’s important that producers make appropriate adjustments in the way that they manage these issues in their animals. This should involve seeking advice regarding alternate chemicals, and other management strategies.
