Interpretive summary: Human salmonellosis outbreaks have been linked to contamination of animal feeds. Therefore, it is critical to use sensitive detection methods. Most Salmonella cells in feed are stressed by dryness and heat used in feed processing. In addition, this study reports that when feeds are tested for Salmonella, the pH of the commonly used media drops during incubation to a level that can kill or severely injure Salmonella which can result in this contamination going undetected.
