Food Safety and Science Lessons

This section addresses the primary risks associated with food consumption and the environmental factors that contribute to illness. It details specific hazards—biological, chemical, and physical—and explains the conditions under which foodborne pathogens thrive.

• Lesson 1: Hazards to Food Safety and Factors that Affect Foodborne Illness

• Keeping Our Food Safe

• Food Contamination

Focusing on the "how" of food safety, these resources cover the mechanisms of food contamination and the critical role of human intervention. Key topics include the biological behavior of bacteria and the practical application of time and temperature controls, as well as the necessity of rigorous hand-washing protocols.

• Time, Temperature, and Hand Washing

This section centers on formal systems used to maintain safety standards in various environments. It introduces Hazard Analysis Critical Control Point (HACCP)—a management system where food safety is addressed through the analysis and control of hazards from raw material production to finished products. It also includes specific applications for food safety within school systems.

• HACCP Introduction

• Food Safety in Schools

• Food Processing

These resources explore the industrial methods used to prepare food while extending shelf life and ensuring safety. This includes traditional processing, as well as modern "enhancing technologies" such as nonthermal food processing and food irradiation, which eliminate pathogens without using heat.

• Food Safety Enhancing Technologies Introduction

• Nonthermal Food Processing

• Food Irradiation: What You Need to Know

The final section introduces the integration of modern data analytics into the food industry. It explores how data science is used to track supply chains, predict outbreaks, and improve the efficiency of safety monitoring systems.
