The CIFOR Industry Guidelines are voluntary recommendations for owners, operators, and managers of retail food establishments (Industry) to clarify Industrys role in a foodborne illness outbreak investigation. The Industry Guidelines and its tools help Industry take an active and educated role in outbreak response, thereby reducing negative economic impact to their businesses. This product was developed by the CIFOR Industry Workgroup, an ongoing public/private partnership consisting of experts from all levels of government and the food industry. The Industry Guidelines are not intended to replace pre-existing company guidelines or local, state, or federal regulations or procedures. Instead, the CIFOR Industry Guidelines are a reference document to create Industry procedures where none may exist, complement existing procedures to fill gaps and update establishment-specific procedures, and to develop specific training content for staff.
