    • E. coli outbreak in the US linked to McDonald’s hamburgers.

    • A mass food poisoning incident in Japan leading to one fatality resulting from contaminated eel rice.

Data on Food Safety from WHO

  • Food safety and nutrition are interrelated, with over 200 diseases stemming from contaminated food.

  • Global Statistics:

    • Annually, 600 million people fall ill, leading to approximately 420,000 deaths.

    • Children under 5 bear 40% of the burden of foodborne diseases.

Factors Contributing to Food Safety Crises

  • Industrialization of Agriculture: Leads to complex supply chains.

  • Trade Liberalization: Global food trade complicates safety measures.

  • Urbanization: Alters lifestyles and increases foodborne illness risk.

Definitions in Food Safety

  • Food Safety (Codex Alimentarius):

    • Assurance that food will not cause harm when prepared/eaten as intended.

  • Harm: Refers to adverse health effects upon consumption.

  • Food Suitability: Ensures food is acceptable for human consumption.

  • Quality vs. Safety:

    • Safety focuses on preventing harm.

    • Quality refers to characteristics that influence a product's value.

Elements of Food Safety Management

  1. Government: Food control authorities oversee enforcement.

  2. Industry: Establishes integrated safety assurance systems.

  3. Consumers: Responsible for knowledge and reporting.

  4. Academia: Provides research and information on food safety.

Challenges in Food Safety Management

  • Balancing safety with consumer expectations on quality.

  • Dealing with a spectrum of biological, chemical, and physical hazards.

  • Complexity of foodservice operations and supply chains.

  • Addressing human factors that contribute to food safety breaches.
