How do people get infected with Salmonella?

Salmonella live in the intestinal tracts of animals, including birds and reptiles. Salmonella usually are transmitted to humans when we eat food contaminated with animal feces or food contaminated by a food handler who forgot to wash his or her hands with soap after handling raw meat, poultry or eggs, or after using the bathroom. Salmonella is also transmitted when contaminated objects or fingers are put into the mouth. The feces of some pets, especially reptiles, can contain Salmonella, and people can be infected if they do not wash their hands after contact with reptiles or their environment. Contaminated food, for example, beef, poultry, milk, and eggs, often originates from animals. However, many foods, including fruits, vegetables, and even flour can become contaminated.
