Salmonella symptoms usually show up within about 6–72 hours after you’re exposed, with most people getting sick around the 12–36 hour mark. In some cases, especially with a smaller dose of bacteria or certain strains, it can take up to about 6 days for symptoms to appear.

Typical timing (Quick Scoop)

  • Most common window: symptoms start 12–36 hours after eating contaminated food or drink.
  • Usual overall range: about 6–72 hours.
  • Possible longer incubation: some sources note it can rarely stretch to several days (up to about 6 days, sometimes even a bit longer depending on strain and host).

What “showing” Salmonella looks like

When symptoms do show, they’re usually:

  • Diarrhea and stomach cramps.
  • Fever, nausea, sometimes vomiting and headache.

These symptoms typically last 4–7 days for most otherwise healthy people, though bowel habits can take longer to fully normalize.

When to worry and get help

Seek urgent medical care or call a doctor if:

  • You have bloody diarrhea, high fever, or signs of dehydration (dry mouth, dizziness, very little urination).
  • You’re pregnant, elderly, have a weakened immune system, or symptoms last more than a week.

If you think you were exposed and feel unwell, it’s safest to contact a healthcare professional, as this information is general and cannot replace personal medical advice.
