Chapter 12: Protecting Our Food Supply

sustainable agriculture

Agricultural system that provides a secure living for farm families; maintains the natural environment and resources; supports the rural community; and offers respect and fair treatment to all involved, from farm workers to consumers to the animals raised for food.

carbon footprint

The total amount of greenhouse gases emitted directly and indirectly by an individual, organization, event, or product, typically measured in units of carbon dioxide equivalents.

food waste

The amount of food produced for human consumption that is discarded or uneaten, leading to resource waste and environmental impact.

organic foods

Products produced without the use of synthetic fertilizers, pesticides, or genetically modified organisms, focusing on sustainable farming practices that enhance soil health and biodiversity.

biological pest management

A method of controlling pests using natural predators, parasites, or pathogens to reduce pest populations while minimizing harm to the environment.

biotechnology

The application of scientific techniques to modify and improve organisms, often used in agriculture to enhance crop traits, increase yields, and develop disease-resistant plants.

genetic engineering

The process of altering the genetic makeup of an organism by manipulating its DNA, often to introduce desirable traits such as improved nutrition, resistance to pests, or tolerance to environmental stresses.

genetically modified organisms (GMOs)

Organisms whose genetic material has been altered through genetic engineering techniques to exhibit traits not naturally theirs, often used in agriculture for improved yield and resistance.

agroterrorism

The use of biological agents to disrupt the agricultural sector, posing risks to food supply and public safety. It can involve attacks on crops or livestock to cause economic harm.

pasteurizing

The process of heating food and beverages to a specific temperature for a set period to kill harmful bacteria and extend shelf life.

viruses

Microbial agents that can infect and replicate within living organisms, causing diseases in plants, animals, and humans.

bacteria

Single-celled organisms that can be beneficial or harmful. They have diverse roles in various ecosystems and can cause infections in humans, animals, and plants.

fungi

A group of eukaryotic organisms that includes yeasts, molds, and mushrooms. Fungi play essential roles in decomposition and can also be pathogenic.

parasites

Organisms that live on or in a host, obtaining nutrients at the host's expense. They can cause various diseases in plants, animals, and humans.

foodborne illness

Illness caused by consuming contaminated food or beverages, often due to pathogens like bacteria, viruses, or parasites.

human immunodeficiency virus (HIV)

A virus that attacks the immune system, specifically targeting CD4 cells, leading to a decrease in immune function and the potential development of acquired immunodeficiency syndrome (AIDS).

toxins

Substances that can cause harm to living organisms, often resulting in illness or other adverse health effects.

irradiation

The process of exposing food to ionizing radiation to kill bacteria and parasites, extend shelf life, and reduce the risk of foodborne illness.

aseptic processing

A method of packaging food in a manner that preserves sterility. It involves heating food to kill microorganisms and sealing it in sterile containers to prevent recontamination.

ultra-high temperature (UHT) processing

A food processing method that involves heating the product to a temperature of at least 135°C for a short time to achieve sterilization, allowing for a longer shelf life without refrigeration.

radiation

The emission of energy as electromagnetic waves or as moving subatomic particles, typically used in food processing to eliminate pathogens.

hemolytic uremic syndrome (HUS)

A serious condition resulting from infection with certain strains of E. coli that leads to the destruction of red blood cells and kidney failure.

danger zone

The temperature range in which bacteria can grow rapidly, typically between 40 degrees F and 140 degrees F. Food should be kept out of this range to prevent foodborne illnesses.

protozoa

Single-celled organisms that can cause illness in humans, often found in contaminated water or food.

helminths

A group of parasitic worms, including tapeworms and roundworms, that can cause various diseases in humans and animals.

additives

Substances added to food to enhance flavor, appearance, or preservation.

direct food additives

Food substances added during processing for preservation or nutritional value.

indirect food additives

Substances not intended as food ingredients but may become part of the food due to packaging, storage, or other handling.

preservatives

Substances used to prevent food spoilage and extend shelf life by inhibiting microbial growth and chemical changes.

delaney clause

Regulation that prohibits the approval of any food additive shown to cause cancer in humans or animals.

cross-contamination

The unintended transfer of harmful bacteria or substances from one food item to another, often due to improper handling or storage.
