OVER the last two decades, more and more Americans have begun patronizing their local farmers markets. From 1994 to 2014, the number of farmers markets throughout the country increased almost fivefold. Many consumers frequent these markets because they believe that the foods they purchase there are healthier and safer than the same items sold at supermarkets, posing less risk of food-borne illness.
Yet no one really knows whether what is sold at farmers markets is less likely to make you sick. For one thing, the publicly available data on food-borne illness from the Centers for Disease Control and Prevention are limited: Only the location where the food was prepared is available, and even that is not always recorded. You cannot use these data to link an outbreak or case of food-borne illness to the specific place where the food was purchased.
