The charges relate to the sale of three heifers destined for the live export market.

Campaspe Crime Investigation Unit detectives last month charged the men, aged 19 and 80, with attempt to obtain property by deception.

They will appear at the Echuca Magistrates' Court on September 18.

Campaspe Crime Investigation Unit and Agricultural Liaison Officer Detective Senior Constable Jason Hare said police had worked closely with Agriculture Victoria as part of the investigation.

"We know that these kinds of incidents can have serious ramifications for the farming community which impacts on the reputation of the Victorian agricultural industry," he said.

"Police take these reports very seriously and we want to reassure the farming community that all incidents are being investigated to the full extent."

Victoria's Acting Chief Veterinary Officer, Cameron Bell said livestock traceability was a key pillar of the state's biosecurity system.

He said livestock traceability provided the ability to rapidly trace livestock and contain disease in the event of an emergency disease outbreak such as foot-and-mouth-disease.

"Failing to record or inaccurate recording of livestock movements could jeopardise our $6.7 billion livestock industries, our reputation for clean, safe food and our important export markets" Dr Bell said.

"Traceability underpins and protects the livestock industry and as a result, everyone in the livestock supply chain has a responsibility, from ensuring livestock are correctly tagged, to recording livestock movements accurately, and completing paper work correctly when livestock are moved."
