Nope that's wrong about the livestock feed. Beef bioaccumulates pesticides in fatty tissue just like anything else. You can't test every steak (yet), but that doesn't mean organic is a scam-- just means it's scammable.

It'd all feel much different if we had more data to empower consumers. Imagine e.g. a meat thermometer that gave ppb/ppt of 100+ pesticide residues.. suddenly you find one kind/cut of meat has orders of magnitude more pesticide than another.. "oh weird I never felt good after eating that brand of meat, maybe I'll pay an extra $2 a pound next time".
