But veggie burgers have been around for 20 years and nobody has been "fooled" into thinking they are beef. The word burger doesn't mean "cow".
The purpose of these laws is transparent, and it's not "consumer protection".
But to say the word "nugget" is restricted to only chicken products is just anti-competitive.
It's ironic turtles all the way down. ;)
Honestly I don't see this regulation as a bad thing. Having to use some different text on your label costs approximately nothing since you have to have a label of some sort so it's not really burdensome. Stores sell margarine beside the butter. I don't see why they wouldn't sell the beef approximation beside the beef. I'm not the target customer though. I won't be buying this stuff until it's so cheap that they start cutting 80/20 beef with it.
[0] per TFA, Europe has very similar laws about food labeling.
Edit: You people have no sense of humor.
RE: burdensomeness of the regulation, another commenter already pointed out the historical usage of the language we're talking about banning. Imagine you spent the last twenty years building your brand around the term "veggie burger." I suspect you would find it burdensome if you suddenly had to change that.
