Maybe something you learned the hard way, or something you found out right before making a huge mistake.
E.g., for audiophiles: don’t buy subwoofers from speaker companies, and don’t buy speakers from subwoofer companies.

I’d say consider where things are growing, too. If you are foraging near roadsides, pipelines, powerlines, houses, or old dump sites, there are things to consider. If you are in somewhere like Appalachia, it’s shocking how common "artisanal " mining sites are when you can recognize them.
Herbicides are often used to keep growth down in those places.
Old houses often have lead paint falling into soil, and leaded gas polluted a lot of roadsides. You don’t want to eat roots/tubers or low growing leafy veggies in those places. Luckily, plants apparently don’t accumulate lead.
