A Food Defense System Is Designed To

A robust food defense system is designed to safeguard the food supply from intentional contamination, aiming to prevent acts of terrorism, sabotage, extortion, or other malicious activities. This system goes beyond traditional food safety measures that focus on accidental contamination, addressing the vulnerabilities that could be exploited by individuals or groups seeking to cause harm. By implementing a comprehensive food defense plan, food businesses can protect public health, maintain consumer confidence, and ensure the continuity of operations.

Understanding Food Defense

Food defense is a critical component of overall food safety, specifically addressing the risk of intentional contamination. Unlike food safety, which primarily deals with unintentional hazards, food defense focuses on preventing deliberate acts aimed at adulterating the food supply.

Key Objectives of a Food Defense System:

• Prevent Intentional Contamination: The primary goal is to deter and prevent intentional contamination of food products.
• Protect Public Health: By safeguarding the food supply, the system protects consumers from potential health risks associated with intentional contamination.
• Maintain Consumer Confidence: A strong food defense system assures consumers that food products are safe and secure, maintaining trust in the food industry.
