I seem to recall a ban on "GMO free" labeling. Not sure if it was nation-wide or not.
Americans who export food to the UK are not allowed to separate GMO foods and not allowed to say what % is GMO.
That seems so fucked up. Under what guise could such a law be allowed to be made? UK should ban American imported food unless it can be known what is in it. Speak with your wallets people, it's the only language they know!

"These outcomes show that in developed countries, thus far, mandatory labeling has failed to provide consumer information and consumer choice. Before the regulations, consumers did not know about GM content, while after implementation of the regulations they do not know more, but all products are basically non–GM (or only contain accidental GM traces under the threshold level)."
Essentially if you tell people that the food has GM content, it gets rejects so the law was made to prevent people from knowing.
