what foods are a major source of salmonella?
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.
