I don't know much about those brands, but I would guess big companies probably don't have to do much to get in on the action. Its sad. People are responding in droves to health, only to be swindled by greed and corruption.
If you want to compete in the organic arena, you should have to conform to the strictest standards, not be allowed to pay off an elected official whose job it is to serve and protect the public. So, in my view its really not big business thats failing, it is the morality of the individuals playing in the game.
