Sentinel Site Program庐
About the Program
We started the Sentinel Site Program庐 in 1999, well before the regulatory requirements of 9 CFR 搂430 were finalized. This program is designed as an ongoing verification of the hazard analysis regarding the potential for post-processing contamination of RTE products with听Listeria monocytogenes听(Lm) in our fully-cooked processing facilities.
Through Sentinel Site, data are collected on a weekly basis from food contact surfaces, non-food contact surfaces, and indirect-food contact surfaces. If a surface returns a positive test result for听Listeria听spp., an investigation is conducted and corrective actions are taken before the line is eligible to resume production. This includes additional data collection, or microbiological sampling, to aid in understanding the scope of the contamination.
Once production has resumed, the surface is subject to what we call 鈥渋ntensified鈥 or more frequent monitoring for听Listeria听spp. to confirm that a harborage does not exist. In the event that any food contact surface on the production line returns a positive test result for听Listeria听spp. concurrent with this intensified monitoring, we immediately reassess the HACCP plan and incorporate a CCP for the control of听Lm. In the event that test results necessitate finished product testing for听Lm, a robust sampling plan is employed. This sampling plan is based upon The International Commission on Microbiological Specifications for Foods (ICMSF) criteria for a severe hazard.
Finally, the Sentinel Site Program庐 also includes provisions for random sampling of finished products. These samples are collected as a verification of the effectiveness of the program.

The pursuit of safer food doesn鈥檛 stop.
Plant surfaces are extensively tested each week. A positive result triggers an听investigation. Any necessary corrective action is taken, and more frequent monitoring is conducted when production resumes.听

World Food Safety Day is an opportunity to raise awareness about things we can all do to improve food safety and recognize individuals who are food safety heroes.
