Again and again it happens. This is why the US must adopt the precautionary principle. A substance must be proven safe with data and studies behind it before it is allowed to enter the food supply or applied in such a way that it escapes into the environment via air, water, or soil. This open beta testing with the lives and health of hundreds of millions / billions of people until harm is conclusively shown is immoral and evil. Lawsuits and money cannot bring back the dead or alleviate needless suffering that should've been avoided by putting caution ahead of profits beforehand.
