Indeed. Until then we hapless individuals trapped in the present will have to resort to heuristics.
The best one I can think of to start with is avoid processing. The more processed a food is the more opportunities it had to potentially be contaminated. Contamination can happen with raw ingredients too, but at least that's fewer opportunities strictly speaking.
So, for example, in order from most dangerous to least:
French fries from a restaurant
French fries pre sliced in a bag but you bake them
Raw whole potatos you yourself slice up and fry in oil you purchased
Raw whole potatos of random origin, baked
Raw whole potatos of known origin, baked
It's very similar idea to eating lower on the food chain to avoid bioaccumulated toxins.
Just a heuristic but can't let the perfect be the enemy of the good. Happens to coincidentally also be a good way to eat healthy in general even ignoring contamination.
PS: if anyone has any other ideas for heuristics I want to know them!
