Waste and loss prevention are the practices of minimizing the amount and value of food and beverage that is discarded or stolen from your food service operation. They reduce your food cost, environmental impact, and risk of fraud. To prevent waste and loss, you need to identify and quantify the sources and causes of waste and loss, such as spoilage, overproduction, portioning errors, theft, or damage. You should also implement and enforce policies and procedures to prevent, reduce, or recover waste and loss, such as FIFO, portion control, security systems, or donation programs.
