A production quality control system now being adopted throughout much of the food industry as a method for minimising the entry of foodborne pathogens into the food supply in order to protect human health. Under a HACCP (pronounced Ha-sip) system, potential hazards are identified and risks are analysed in each phase of production; critical control points for preventing such hazards are identified and constantly monitored; and corrective actions are taken when necessary. Record keeping and verification procedures are used to ensure that the system is working.

HACCP is one of the major elements of regulations, issued by USDA in July 1996 to control pathogens in meat and poultry products. Under the rules, all meat and poultry slaughter and processing plants with 500 or more employees had to develop and implement, by January 1998, a USDA-approved HACCP plan for each of their processes and products. Plants with 10 to 500 employees implemented HACCP by January 1999, and plants with less than 10 employees implemented the system by January 2000. Under separate rules issued by the Food and Drug Administration on December 5, 1995, seafood processors and importers also were required to implement HACCP plans and be in full compliance by December 1997.
