A systems-based food safety evaluation: an experimental approach

Area of Science:

• Food safety science
• Systems theory application in public health
• Environmental health assessment

Background:

• Food establishments are complex systems influenced by various factors.
• Existing food safety protocols can be enhanced by systems thinking.
• General Systems Theory provides a framework for analyzing complex environments.

Purpose of the Study:

• To translate systems theory and hazard analysis concepts into a practical food safety assessment methodology.
• To develop and test a novel systems-based approach for evaluating food service establishments.
• To improve food safety practices within the National Park Service.

Main Methods:

• Development of an experimental systems-based methodology.
• Application of General Systems Theory principles to food service operations.
• Integration of Hazard Analysis Critical Control Point (HACCP) concepts.
• Field testing and refinement of the assessment approach by the NPS Public Health Program.

Main Results:

• A comprehensive systems-based methodology for assessing food establishments has been drafted and developed.
• The methodology provides a structured framework for understanding and evaluating food safety risks.
• Initial testing indicates the approach's potential for improving food safety in real-world settings.

Conclusions:

• A systems-based approach offers a valuable framework for enhancing food safety assessments in complex environments.
• The developed methodology provides a practical tool for public health programs to improve food establishment safety.
• Continued application and refinement of this approach can lead to significant advancements in food safety management.
