A study of health data shows that as the per-capita number of farmers’ markets rises in a given U.S. state, so does the per-capita incidence of food-borne illnesses, says a team led by Marc F. Bellemare of the University of Minnesota. A doubling of the number of farmers' markets in the average state-year would be associated with an economic cost of more than $900,000 in additional cases of food-borne illnesses. The reasons for the effect are unclear; consumers may be less careful about washing and handling foods purchased from farmers' markets, the researchers say.
