places that make vegan food but come from non vegan places

M
Do you trust them? I ended up getting sick after eating something vegan that came from a place that manufactures eggs and milk. Now I though about it and I don't want to support not only non vegan products but non vegan buinesses. You vote with your dollar and I choose to vote for places that are trying to be better. Plus I don't trust places that are non vegan but make naturally vegan products. How do you guys feel? Do you buy naturally vegan products from places that are not vegan? Do you trust them?
