Street foods are sold in almost every country in the world. Many urban and rural people depend on them for one or more meals each day. This book explores this world of entrepreneurs in developing countries. When all of the participants in the delivery are counted, including local farmers, food processors, and street vendors, one realizes the enormous size of this `industry'. Research conducted by the authors with vendors, local community leaders, and public health officials, worked not only to collect data, but to raise the hygiene of the food that is sold.
