How Long Does Food Poisoning Usually Last?
Food poisoning typically lasts 1-7 days, with most cases resolving within 3-5 days. The duration depends on the type of bacteria or virus involved and your immune system's response. Common culprits like Salmonella usually clear up in 4-7 days, while norovirus often resolves in 1-3 days. Severe cases involving E. coli or Clostridium botulinum can last weeks and require medical attention. Most people recover completely at home with rest and fluid replacement. Symptoms like severe dehydration, high fever over 102°F, or bloody stools warrant immediate medical care.
