  • Cross-Contamination: the transfer of microorganisms from one surface to another, which can occur during food preparation, handling, or storage.
  • Labeling and certification: regulations that require food manufacturers to label their products with information about ingredients, allergens, and nutritional content.

Global food systems

  • Agricultural Systems: the methods used to produce crops and raise livestock for food production. Examples include intensive farming, organic farming, and agroforestry.
  • Food Distribution Networks: the systems that transport and store food from farms to consumers. These networks can be locally focused or global in scope.

  • Food Manufacturing: the production of packaged and Processed foods using machinery and equipment.
  • Food Robotics: the use of robotic systems for tasks like food preparation, packaging, and delivery.

Food and Ethics

  • Animal Welfare: the treatment and handling of animals in food production, including Farm animal welfare, transportation, and slaughter practices.
  • Environmental Stewardship: the conservation of natural resources, biodiversity, and ecosystems to ensure sustainable food systems.
  • Social Justice: the fair distribution of resources, opportunities, and benefits from food production and consumption.
