If it's important to you, I would suggest maybe approaching it from the other direction. (The *traditional* direction, in fact )it's frustrating when you're doing your best to try to be responsible about what you consume...when you can't even figure out where it's really made
Rather than "this is what I want, what brand/source shall I buy?", you can instead approach it as "I am looking around and here are the local-sustainable-whateverelseIcareabout things available to me, now how much variety can I generate from those ingredients".
You may well still choose to buy other ingredients from further away or more mysterious sources; but at least you will be buying as MUCH known-origin food as possible.
It may however necessitate cooking according to what you have on hand, rather than the modern habit of cooking according to whim.
