Study Notes
Introduction to Food Safety
- Norovirus is the most common cause of food-borne disease outbreaks in the United States.
- Food can become contaminated with pathogens or their toxins during production, processing, and preparation.
Food-Borne Illnesses
- Food-borne illnesses occur when people consume foods or beverages that contain certain microbes, natural or human-made toxins, or other contaminants.
- Pathogens, such as norovirus, are disease-causing agents that can make food unsafe to eat.
- There are over 250 kinds of food-borne illnesses.
Food-Borne Infections vs. Food-Borne Intoxications
- Food-borne infections occur when pathogens infect the digestive tract, inflaming tissues and causing symptoms within a few hours of ingestion.
- Examples of food-borne infections include norovirus and other pathogens that multiply in the human intestinal tract.
- Food-borne intoxications occur when pathogens contaminate food and secrete poisons, which irritate the intestinal tract and cause symptoms when ingested.
Impact of Food-Borne Illnesses
- An estimated 48 million Americans become sick from food-borne illnesses each year.
- Of those, 128,000 require hospitalization and 3000 die.
- Promoting food safety efforts is a major goal of U.S. public health officials to prevent these diseases.
