An accident is when you accidentally poop in your pants. The US government sacrifices the health of its own citizens for corporate profit, it even bullies foreign nations and most of the globe on behalf of its multi-national corporations. This is all no accident. Governments in capitalist societies sacrifice the public for profit and growth. They know that milk has health risks, if you ever get a chance watch the documentary:
Got the Facts on Milk? (2008) it does a good job exposing that.
The US government is not wrong, it is just doing what it has always done assisting large, local corporations. Now if milk could or did suddenly start killing people alot faster and sooner in life, then the government would intervene against milk or those suspected batches of milk. Otherwise it will do nothing against large corporations. It only intervenes to save capitalists from themselves, like a release valve.
