Salmonella bacteria live in the intestines of people, animals and birds. Most people are infected with salmonella by eating foods that have been contaminated by feces. Commonly infected foods include: 1  Raw meat, poultry and seafood. 2  Feces may get onto raw meat and poultry during the butchering process.
Fresh fruits and vegetables can become contaminated before or after harvest. Contaminated seeds, irrigation water, and flooding have contributed to Salmonella outbreaks traced to sprouts, lettuce, and other fresh produce. Unpasteurized orange juice has been the source of several Salmonella outbreaks. Water intended for recreation (e.g., pools, shallow lakes) and for human consumption can also become tainted with Salmonella. When lakes become contaminated with Salmonella, several weeks or months can be required for water quality conditions to improve or return to normal.
