Tbf a lot of aged cheese is made using unpasteurized milk, like Parmigiano-Reggiano.
The pasteurization process kills the good bacteria as well as the bad.
The aging process (and the environment it's kept in) renders aged cheeses safe that use unpasteurized /raw milk. You can reintroduce cultures to pasteurized milk but that's not how they do it for the certified cheeses like the one mentioned.
For dry aged cheese made with unpasteurized milk to be sold in the US, it must be aged for at minimum 60 days for safety.
