Street food is food obtainable from a streetside vendor, often from a makeshift or portable stall. While some street foods are regional, many are not, having spread beyond their region of origin. The food and green groceries sold in farmers' markets may also fall into this category, including the food exhibited and sold in various gatherig fairs, such as agricultural show and state fair. Most street food is both finger and fast food. Food and green groceries are available on the street for a fraction of the cost of a restaurant meal and a supermarket. According to the Food and Agriculture Organization, 2.5 billion people eat street food every day.[1]

Concerns of cleanliness and freshness often discourage people from eating street food. Lack of refrigeration is often construed as a lack of cleanliness or hygiene; on the other hand, street food often uses particularly fresh ingredients for this very reason.[citation needed]

Street food is intimately connected with take-out, junk food, snacks, and fast food; it is distinguished by its local flavor and by being purchased on the sidewalk, without entering any building. Both take-out and fast food are often sold from counters inside buildings. Increasingly the line is blurred, as restaurants such as McDonald's begin to offer window counters.

With the increasing pace of globalization and tourism, the safety of street food has become one of the major concerns of public health, and a focus for governments and scientists to raise public awarenesses.[2],[3],[4],[5] FSA hence provides comprehensive guidances of food safety for the vendors, traders and retailors of the street food sector.[6] Other effective ways of curbing the safety of street foods are through mystery shopping programs, through training and rewarding programs to market stallers, through regulatory governing and membership management programs, or through technical testing programs.
