Foodborne describes illnesses or diseases that spread through contaminated food. When harmful bacteria, viruses, or other germs get into what we eat or drink, they can make us sick. That sandwich sitting in your backpack all day in the sun? It could develop foodborne germs that give you a stomachache or worse.

Foodborne illnesses happen when food isn't handled, cooked, or stored properly. Raw chicken left on a cutting board can spread bacteria to vegetables cut on the same board. Milk that sits out too long can grow harmful germs. Unwashed hands can transfer germs to food during preparation.

Common foodborne illnesses include salmonella (often from undercooked eggs or chicken) and E. coli (sometimes from undercooked beef or unwashed vegetables). Symptoms usually include stomach cramps, nausea, vomiting, or diarrhea. Most people recover within a few days, but foodborne illnesses can be serious, especially for young children and older adults.

This is why restaurants have strict rules about food safety, why we refrigerate leftovers quickly, and why cooking food to the right temperature matters. When you wash your hands before cooking or make sure meat is fully cooked, you're helping prevent foodborne illness. The term reminds us that food, while delicious and necessary, can also carry invisible dangers if we're not careful.
