The next hundred years is probably going to be grappling with how many toxic chemicals we allowed at 'safe' levels because it was inconvenient to industry to ban them the same way we're floored by the casual irradiation of the early 20th century.
The burden of proof is upon those introducing novel substances into my food.
They funded a state-of-the-art ecotoxicology research lab next to where I live, that was going to do pioneering work in the field, within a university-industry cooperation framework. As coincidence would have it, once the first results started coming in, there was a lot less interest from the industry in cooperation. The lab now runs at a fraction of its capacity.
But in the case of interaction between substance A and B from different vendors, who's responsible?
People are going to scream about the cost of remediating all of this (hundreds of billions, if not trillions), but it was just shareholders through limited liability corporations stealing from taxpayers (who will end up with the remediation bill through taxes) by way of the market and government, with enormous aggregate harm a second order effect. So long, and thanks for all the poison.
