> but interests of corporate mega producers they can't guarantee such thing at scale. So to protect them and people from them these laws are made kind of impossible triangle.

In North America, many of these laws were passed in the early part of the 1900s [1]. I don't think that were very many mega producers at the time, though I'd love to be proven wrong.

Also in my experience it's really hard to avoid contamination. My family farm works hard to keep their cows healthy, happy, and clean, and still has occasional issues with high somatic cell counts in their milk. It doesn't help that cows will (rarely) decide to release their bowels while you're milking them...
