“Almost all dairy nowadays is pasteurised and that will kill the virus,” Rossman explains. “So for the vast majority of people drinking milk, there’s absolutely no reason to be concerned.”
“The only potential concern at all would be people that are drinking unpasteurised milk. But of course, if you're drinking unpasteurized milk, you also have a risk of a lot of other infections that could occur.”
The states affected so far are Idaho, Kansas, Michigan, New Mexico, North Carolina, Ohio, Texas and South Dakota.
In the US, the FDA has banned sale of unpasteurized milk, but that only affects stuff that crosses state lines; they don't have authority to ban within a state. Some states allow sale of unpasteurized milk -- stuff gets produced and sold in the state.

Idaho and New Mexico, both affected states, permit sale of unpasteurized milk directly in stores.
And this doesn't just affect some person who is absolutely determined to disregard health advisories and drink raw milk in those states. If the virus jumps to humans there and begins human-to-human transmission off one of them, the whole world can potentially be impacted.
I mean, with COVID-19, we spent a lot of time early-on dinging China for having wet markets that helped create risk for disease jumping animal-human barriers. This is also not good.
