Food safety is a scientific discipline describing handling, preparation, and storage of food in ways that prevent foodborne illness. This includes a number of routines that should be followed to avoid potential health hazards. In this way food safety often overlaps with food defense to prevent harm to consumers. The tracks within this line of thought are safety between industry and the market and then between the market and the consumer. In considering industry to market practices, food safety considerations include the origins of food including the practices relating to food labeling, food hygiene, food additives and pesticide residues, as well as policies on biotechnology inspection and certification systems for foods. It is important for people to understand how their behavior and activities contribute to the safety of food and how they can decrease the risk of foodborne illness. From processes on the farm to practices in the kitchen, human activities play an important role in food safety.
