I know people who have been drinking raw milk for years, and they never got sick. Why is that?

This could be a Myth associated with Raw milk. If somebody never got sick could be a co-incidence.

Normally raw milk is not sold in the market freely. It comes after processing and very small population (may be milk producers - farmers) drink raw milk. Statistics available will be too less to see the significance of this belief....

Yes, Raw milk is good with respect to freshness and taste. But, it will have lots of fat!! which is not good for all. It is proven fatty milk products are dangerous to heart!!

Any infectitious bacteria in cow milk can easily infect childs.

Better to avoid raw milk.....
