OP, please. Smell, followed by taste. Just tasting milk that has gone bad won't hurt you.
Also, OP, I love raw milk. Up until a couple of years ago, I could get it 10 minutes away from some Mennonites. Due to strict regulation, the raw milk anyone can purchase is the healthiest milk you can get, since the cows have to past VERY HIGH LEVELS of hygiene.
Sans that, I prefer at least to get unhomogenized milk. The less processing the better. I can still get that from the Nazi milk fraulien 15 minutes away. The cows are right there. They don't pump them with any hormones, and the milk came out that day (or the day before.) Freshness counts, too.
However, your claim that pasteurized milk is toxic is bunk.
How old are you?
