Food safety matters to everyone. Food-borne illness caused by harmful pathogens that contaminate food supplies can potentially affect the health of hundreds of millions of people worldwide. It is also a major concern for food growers, manufacturers, packers, shippers, wholesalers, and retailers. Release of contaminated foods can result in processing delays, product recalls, plant shutdowns, and legal action. It can cost food companies millions in revenue as well as their reputation, stock value, and future profitability.
