According to a Washington Post article, the FDA argues that it cannot label the fish as GMO because it is indistinguishable from non-GMO fish. Translated from government-speak, that means that food lobbyists are pressuring the agency to let this slide through.
In addition to being an important battle on its own merits, this is a test case since this is the first genetically modified animal food product headed to market. You can visit the Government Regulations site and search for the words gmo+salmon and the resulting links will allow you to leave your own comment.
Whole Foods again disappoints (remember when former Whole Foods CEO John Mackey came out against Obamacare?) by continuing to sell endangered fish, though the is a labeling system to warn you that the fish sold with a red dot are in short supply or are produced using environmentally damaging practices. What we really need is a big skull and crossbones, maybe in ocean blue, instead of a system that requires an engineering degree to decipher.
As an atheist, am I allowed to believe in the End Times? Sure seems like clear signs to me.
