Pork producers have a beef with impossible pork.

As Impossible Foods debuted its latest plant-based food offering at the Consumer Electronics Show this week, the National Pork Producers Council (NPPC) called out the company for violating food labeling laws.

Citing law that prohibits the use of words that redefine pork as it has been known by consumers for centuries, Dr. Dan Kovich, director of science and technology for the National Pork Producers Council, issued the following statement:

“What’s impossible is to make pork from plants. This is a brazen attempt to circumvent decades of food labelling law and centuries of precedence. Any adjective placed in front of the word pork can only refine it, not redefine it. It’s not pork. It’s not pork sausage. It can’t be labelled as such.”

The pork producer group’s position is that plant-based and cell-cultured products designed to mimic real meat must face the same stringent regulatory requirements as livestock agriculture, including truthful labeling standards.
