What Are Food Borne Diseases
Food borne diseases are illnesses caused by consuming contaminated food or beverages. Pathogens such as bacteria, viruses, and parasites, or their toxins, enter the body through the mouth. Common examples include salmonellosis, norovirus infection, and listeriosis. Symptoms often appear hours to days after eating and can range from mild stomach discomfort to severe dehydration or hospitalization. According to the World Health Organization, unsafe food causes millions of illnesses worldwide each year, with children and older adults at higher risk of serious complications.
Common Causes and Symptoms
Contamination can occur at any stage of the food supply chain, from farm to fork. Poor hygiene, undercooked meat, cross-contamination, and improper storage temperatures are leading causes. Typical symptoms include nausea, vomiting, diarrhea, abdominal cramps, and fever. Most cases resolve within a few days, but some infections require medical treatment. Seek care if symptoms are severe, persistent, or accompanied by high fever or bloody stools.
Prevention and Safe Food Handling
Preventing food borne diseases relies on basic food safety practices. Wash hands and surfaces often, separate raw and cooked foods, cook to safe internal temperatures, and refrigerate leftovers promptly. The U.S. Centers for Disease Control and Prevention provides detailed guidance on reducing risk at home.
