How long can salmonella live after being exposed to air?

Salmonella can survive outside the host for varying periods, depending on environmental conditions. In dry environments, it may last only a few hours, while in moist conditions, it can survive for days to weeks. Factors such as temperature, humidity, and the surface it contaminates also influence its longevity. Overall, proper food handling and hygiene are essential to minimize the risk of salmonella contamination.
