I myself would trust produce from smaller local farms more than larger farms, however I also live near the farms and know what is in season and don't deal with the problems of people reselling food like they often do in "farmers markets" near or in large urban centers.

Small farms just don't have the pressure, or the large amount of disinterested or temporary employees that large farms have.

Same with smaller slaughter houses. Perhaps they don't have the manpower to deep clean every shift, but they also don't process nearly as much stuff, don't churn through employees as fast, more directly handle and train employees, and don't have some crap corner of the factory where people can be messing around being dumb.

Of course none of that is bullet proof, but small farms and slaughter houses know that if they fuck things up they don't just lose a bit of money and have to deal with some legal problems like Tyson or other large suppliers and distributors, they lose literally everything.
