Almond milk, vegan cheese and veggie sausages will have to be known by different names if the National Party has anything to do with it.

The Nationals are calling for a major overhaul of food-labelling rules that would stop plant-based milk and meat companies from using the terms "milk", "meat" and "seafood" to market their products.

A meeting of the party's federal council in Canberra on Saturday voted to pressure the Morrison government to crack down on labelling requirements. Agriculture Minister Bridget McKenzie, who is also the deputy leader of the Nationals, said there was an increasing awareness of the need to "call things for what they are".

"I'm not anti plant-based protein foods, I think they're going to have a role to play in the food proposition going forward. But that means then we need to be very clear with consumers about what they're purchasing," Senator McKenzie said.
