I suppose they would think nothing of serving raw fish but they are against the Amish for using raw milk for 400 years.
Chilling milk does little to kill the bacteria that are commonly found in unpasteurized milk.
The Amish have been around for maybe as long as 600 years, albeit with different names ~ at the same time they and everybody else used to drink raw milk, and suffered a death rate sufficiently high that European populations actually did not increase in number.
