E. Coli Infection is caused by the bacterium Escherichia coli, which normally lives in the intestines of healthy people and animals. Some strains can lead to severe stomach cramps, diarrhea, and vomiting. Infection often occurs through contaminated food or water, particularly undercooked meat, unpasteurized milk, or raw vegetables. Most people recover within a week, but some may develop serious complications, such as hemolytic uremic syndrome, which can lead to kidney failure. To prevent infection, it is important to practice good hygiene, cook food thoroughly, and wash hands regularly, especially after handling raw meat or using the restroom.
