What is the incubation period for salmonellosis?

Salmonellosis typically presents symptoms after a short window following ingestion, about 6 to 72 hours. This range is the best answer because it covers both the earliest possible onset (as soon as around 6 hours) and the latest commonly observed onset (up to about 72 hours). The other ranges are narrower or start later and can miss part of the usual timeline—for example, 12–24 hours misses very early or later onsets, 24–48 hours misses earlier onsets, and 1–3 days (24–72 hours) excludes the possibility of symptoms starting as soon as 6 hours. In practice, you’ll often see onset around 12–36 hours, but the full typical window is 6–72 hours.
