Another hidden cost of food production: worker healthcare

Add another externality (or unaccounted cost) to the food chain: the cost of healthcare for undocumented workers, many of whom turn to risky alternative medicine.  It is time to consider that the people who handle our food live in the most unhygenic conditions.  Doctors worry that indiscriminate use of illegal Mexican antibiotics will give rise to drug-resistant strains of human diseases.  From the infected hand of the farm worker it is a short hop to your dinner plate.
