Claims farmers were taking their own lives in the wake of the dairy crisis were aired again during Wednesday’s Farmer Power rally in Melbourne.

Detective Senior Constable Wayne Ryan of Warrnambool police said there had not been any suicides that could be related to the milk price drop in the south-west.

“Mental health issues are difficult enough without people putting unfounded rumours around,” he said.

Member for South West Coast Roma Britnell said the claims were “unhelpful and completely unfounded” as there was no evidence of any suicides in Victoria related to milk prices.

“We have been hearing the rumours from across the state and have been looking into them,” Ms Britnell said.

“But there has been no evidence they have actually occurred. That’s the way we want to keep it. These rumours are unhelpful and completely unfounded.”

Lifeline South West Victoria community engagement manager Carly Dennis said spreading such rumours was “dangerous”.

“People should realise something like this is more likely to make people more vulnerable,” Ms Dennis said.

“The conversation in the community can be very dangerous. We need to look at what people can do that’s positive. We need to look out for community members, tell them it’s okay to not feel great, to open the conversation, and let them know people there are people out there that can help.”

A spokesman for the United Dairyfarmers​ of Victoria said there was "no evidence of suicides attributable to the dairy price cut".

Victorian Farmers Federation president Peter Tuohey said spreading such claims was “irresponsible”.

"It distresses the whole industry, the whole community," Mr Touhey said.

"That could actually distress people enough, (who are already) in a distressed state they are, it could actually cause them to think well if other people are doing it they might do it themselves," he said.

A Farmer Power statement released just days after Murray Goulburn announced its milk price drop stated “abattoirs are now working at capacity to kill off Australia’s dairy herds, and there are alarming reports of farmer suicides”.

Farmer Power representative Jane Stanley refused to back down from the claims farmers had committed suicide because of the price drop, instead repeating claims of up to 13 deaths.

She said she had no evidence to support the claims.

“It’s not our job to validate (the number) of suicides,” Dr Stanley said.

“I’m satisfied that it’s happening but families don’t want it known. It’s the sort of issue that should be on the front page of papers.”
