It was reported in October that members of the European Parliament had voted to reserve these names for meat products, and it is understood the European Commission may decide on the ban later this week.Â
Sir Paul, 83, is a staunch advocate for vegetarianism and co-founded the Meat Free Monday campaign alongside his daughters Mary and Stella in 2009.
His late wife Linda McCartney set up a food brand in the 1990s that sells plant-based sausages, burgers, pies and more.
"To stipulate that burgers and sausages are 'plant-based', 'vegetarian' or 'vegan' should be enough for sensible people to understand what they are eating," the Beatles star said.
"This also encourages attitudes which are essential to our health and that of the planet."
A letter signed by the McCartney family and a cross-party group of UK MPs said while the UK is no longer in the European Union its markets, companies, consumers and regulatory conversations remain closely intertwined.
"Decisions taken at EU level continue to influence global norms, international trade and the direction of sustainable food innovation," the letter read.
"We urge you not to adopt these restrictions as we are deeply concerned about the significant global impact they could have."
Sir Paul has previously called for an end to mandatory meat in England's school meals and earlier in the year he sent a letter to COP30 president Andre Correa do Lago and asked that the conference adopt a fully meat-free menu.
