5. Salmonella epidemiology

Salmonella lives in the intestinal tracts of humans and many other animals. It is usually transmitted to humans who eat foods of animal origin, such as beef, poultry, milk, or eggs that have been contaminated with animal feces. Animal feces can also contaminate a wide variety of foods that do not come from animals, such as fresh produce. Salmonella may also be found in the feces of pets, especially those with diarrhea. Contact with these animals or their feces can lead to an infection if appropriate hygiene practices are not followed, such as proper handwashing after animal contact.
