You want to get their interest, but as this might be one of those deal breaker questions, you should get it out of the way early. There's no shame in breaking up from an incompatibility in attraction or sexual preference, but there should be some shame at sticking with it expecting another person to change for you.
Not really. Even old fashioned farmers boil their milk. Almost all milk contains dangerous bacteria regardless of what the safety standards are; this is because things like e.coli are natural for cows but harmful to us humans. Like imagine defending a practice that can literally kill you or give you life long digestive problems.
Fun fact, e. Coli is a family of bacteria, most of them are harmless to humans. They are even a part of many diet supplements.
Also I don't know where you live and what your food standards are, but here in Europe you can drink raw milk quite safely and there are plenty of raw milk products like cheese. It's literally a non issue.
Have you actually talked to a microbiologist about this? It's not safe at all.
E.coli might have some harmless strains, but you have no guarantee which strain is present. It's also not the only dangerous pathogen found in milk. Did I mention raw milk is often contaminated with bacteria from cow poo?
Just because something is fine for a calf doesn't mean it's fine for you and vice versa.
Edit: oh yeah and I live in England. We have decent food safety standards here and that's why raw milk isn't sold at supermarkets.
Raw milk is not sold at supermarkets because its shelf life is like one day. But you can buy raw milk directly from farmers or even from the Borough Market.
