We aren't importing unpasteurized milk.
The Amish seem to do just fine on subsistence farming. But that's because they are willing to live like they did 100 years ago. They aren't buying the satellite dish or the latest cell phone.

The FDA - who I feel I should point out are another regulatory body of the United States like the EPA - have carried out dozens of armed raids on people who sell unpasteurized milk: also organic produce and natural supplements.
