What is the primary source of Salmonella?

The primary source of Salmonella is the intestinal tract and feces of humans and animals. Salmonella bacteria are commonly found in the intestines of many animals, particularly birds, reptiles, and mammals. Transmission occurs when food or water contaminated with feces from these animals is consumed. This highlights the importance of proper hygiene practices in food preparation and handling, as well as adequate cooking, to eliminate the bacterium and prevent foodborne illness.

Contaminated fruits and vegetables, while potentially a source of Salmonella, reflect secondary contamination and are not the primary origin of the bacteria. Similarly, unpasteurized dairy products can harbor harmful bacteria, but they are not the main reservoir for Salmonella, which is more closely associated with animal feces. Processed foods with artificial additives do not typically pose a direct threat for Salmonella unless they are contaminated during production, storage, or preparation.
