It’s rather the other way round. Pasteurization was invented at the end of the 19th century and quickly becoming widespread in the beginning of the 20th century (1910 in NY) when it was no longer feasible to have cows in urban centers and transportation took significant time. However, since then, the industrialization of milk production and the introduction of safety standards (cold storage, stainless steel vats to transport, mandatory testing,...) made processing raw milk safer, rather than riskier. Major TBC outbreaks were linked to raw milk - TBC linked to milk is basically a non-issue nowadays, even for raw milk.
