The problem is less the raw milk than the treatment/transport. Drink uncooled within 15 minutes of milking, when instantly cooled: on the same day. Do not swap containers more than 2-3 times.
Which basically means: only available next to the barn the cows are milked in.
If there is dirt in the milk (or on the udder) then I'd avoid the rancher and their products regardless of raw or cooked.
Manually and (more often) with machine. But never without thoroughly cleaning the udder before so.
They are. That's why the thorough cleaning. And the minimised "good" time, instant cooling, etc. (even if the milk was not sold raw).
Milk from bloody/inflamed udders or ill cows was separated and discarded or treated separately.
My uncles seriously enforced these basic hygiene rules. Against repeat offenders ... sometimes also forcefully.
