What are the symptoms of salmonella infection in humans?
Once Salmonella has been ingested, the "incubation time" or period from ingestion until the first symptoms of illness occur ranges from 12 to 72 hours. The time to illness may vary depending on many things such as the host's overall fitness and age, the amount and serotype of Salmonella ingested (with some serotypes as few as 20 cells), and the presence of various "stress" factors such as whether the person is undernourished, etc.
