They’ve targeted farms and slaughterhouses - now vegan activists have taken their latest protest to a Perth supermarket.

Video filmed at Woolworths Melville on Saturday and has drawn a mixture of support and criticism online.

Posted to Facebook with the captions “Welcome to the death aisle” the video shows a woman dressed in a cow onesie approach the meat section of the supermarket.

She slumps to the ground and looks at the meat, appearing to ‘mourn’ it.

The woman then lies on the ground holding a sign saying “You’ve been lied to - Youtube ‘Dominion’”, an animal rights documentary.

Tash Peterson, who posted the video, says she filmed the stunt to raise awareness for their cause and get a message out to consumers.

Premier Mark McGowan was not a fan of the strategy.

“All they do is drive people away from their cause if they disrupt the community in supermarkets or restaurants. Don’t do it,” he said.

A Woolworths spokesperson said the activists were asked to leave by a staff member and did so.

Founder of Direct Action Everywhere James Warden faced court last week accused of trespass and stealing a calf worth $1500.

He was recently fined for live streaming himself at a Pinjarra piggery.

The group say it plans to target more supermarkets over coming days.
