Typhoid fever and paratyphoid fever are serious illnesses. They occur most often in developing countries where sanitation is poor.
Typhoid fever is caused by eating foods or drinking beverages contaminated with the Salmonella bacteria. Contamination can occur from:
- Food or drinks handled by someone who is sick with typhoid fever
- Food or drinks handled by someone who has no symptoms but carries the bacteria
- Sewage contamination of water or food
- Unpasteurized dairy products
- Unrefrigerated poultry products
