The Lonely Planet guide for Mongolia uses "boiling milk" and pasteurization interchangeably:
TB is a bacterial infection usually transmitted from person by coughing, but which may be transmitted through consumption of unpasteurised milk.
Milk that has been boiled is safe to drink, and the souring of milk to make yoghurt or cheese also kills the bacilli.
The Wikipedia article on pasteurization mentions various time periods and temperatures as qualifying as pasteurization.
But I don't know what the term "boiling milk" means. In particular, I don't know whether "boiling milk" always means pasteurization. Is there a time and duration that'd qualify as boiling milk, but wouldn't count as pasteurization?
Failing that, in Mongolia, does "boiling milk" always equate to a time and temperature that'd achieve pasteurization?
