Police raided a Rockbank, Australia property this week with representatives from the RSPCA, Melton Shire Council, the Department of Sustainability and Environment (DSE) and the regulator responsible for meat safety, PrimeSafe.

"The other agencies attended the residential address in relation to information about possible wildlife and animal cruelty offences, as well as the alleged production and selling of meat," a police spokeswoman said.

An RSPCA spokesman said 22 dogs of varying breeds were found and about 100 goats, one of which had to be euthanased on humane grounds.

PrimeSafe chief executive Brian Casey said two goat carcasses were found and about 20 kilograms of sheep or goat meat was discovered in a freezer.

There was no evidence dogs had been slaughtered, he said.

In Victoria it is illegal to slaughter non-consumable animals such as dogs, horses, cats and donkeys.

"You can slaughter consumable animals [such as goats] but they must be slaughtered at a licensed abattoir," Mr Casey told AAP.

There was an exemption in place to enable farmers to slaughter edible animals on their properties for their own consumption, but the Rockbank property was not a farm, he said.

More than 45 animals were seized by DSE including 30 frogs, four central bearded dragons, a children’s python and a crucifix toad, which were being kept illegally.

"A wildlife licence is required by anyone keeping and trading protected wildlife in Victoria."
