The infectious period can vary from several days to many months. Those who have been treated with oral antibiotics tend to carry the microorganism longer than others. Infected food handlers, health care workers, and individuals associated with daycare must obtain the approval of their local health department before returning to work or daycare. Most people recover on their own without medication. Antibiotics and antidiarrheal drugs are generally not recommended.
Some people require intravenous fluids to prevent dehydration.
Wash your hands with soap and warm water before and after handling foods, after using the bathroom or changing a baby's diaper, and after contact with animals. Make sure children, particularly those who handle pets, wash their hands properly. Purchase only inspected eggs, animal food products and pasteurized milk. Wrap fresh meats in plastic bags at the market to prevent blood from dripping on other foods. Refrigerate foods promptly.
