But the potential for serious disease is real, and it's a good bet that many of these poor immigrants don't have health insurance. So if they do get some strange disease from uncooked whatzit meat, they'll be in the ICU, getting treated on the taxpayer's dollar. Given that situation, and the risk of contaminating safe food supplies that most people prefer, some kind of regulation may make sense here.
Maybe someone should check our refrigerators daily to make sure that package of USDA inspected ground beef hasn't been thawed too long. While we're saving medical expenses, let's make children prove they have coverage to ride a bike or play ball. Both these activities cause more hospital visits than eating mystery meat.
The point is that we have developed a system which aims to ensure that we have wholesome food. The prospects of a large outbreak of cholera, hepatitis or other food/waste- associated disease increases dramatically when there is a source of uninspected food being provided by and for a large, isolated population of people, many of whom haven't had the basic health screening required of legal immigrants.
