The rabies virus
is inactivated by heat and consumption of cooked meat and/or pasteurized milk from a rabies positive animal is not considered a rabies exposure. It is however, theoretically possible for the rabies virus to be shed in milk and there are studies underway to isolate the rabies virus from udders of cattle that have died from rabies. Until that mode of transmission is fully proven or disproven, drinking unpasteurized milk from a rabid cow or buffalo should be avoided since it is considered a rabies exposure.
Since all most everybody drinks milk after boiling it,the chances of rabies are as good as nil.
