About Campylobacter Infections
Campylobacter infection is a common foodborne illness. You usually get it from eating contaminated food, especially raw or undercooked poultry. You can also get it from drinking contaminated water or raw milk, or handling infected animal feces (poop).
Some infected people don't have any symptoms. If you do have symptoms, they start two to five days after you are infected. They usually last about one week, and can include:
- Diarrhea (which could be bloody)
- Cramping
- Abdominal pain
- Fever
- Fatigue
- Nausea and vomiting
Health care providers use stool tests to make a diagnosis. Most people get better without treatment. You should drink extra fluids for as long as the diarrhea lasts. People who have a severe infection or a weakened immune system may need to take antibiotics. In rare cases, the infection can cause reactive arthritis or Guillain-Barre syndrome.
To prevent Campylobacter infection, cook poultry thoroughly. Use a separate cutting board and utensils for meats. Make sure to clean them carefully with soap and hot water after you use them.

When to speak to someone. Reading about a topic cannot tell you whether it applies to you. Speak to a doctor or pharmacist if symptoms are severe, sudden, getting worse, or simply not going away — and seek emergency care immediately for chest pain, breathing difficulty, sudden weakness or confusion, or a serious allergic reaction.
Research on Campylobacter Infections
17 studies areregistered for this condition on ClinicalTrials.gov, the U.S. National Library of Medicine's public registry. A selection is below — the links go straight to the registry entry, not to a summary of ours.
What a registered study does and does not mean. Registration means a study exists and has been declared publicly. It says nothing about whether the treatment being tested works, is safe, or is available to you. Many studies find no benefit — that is what research is for. Never seek out an experimental treatment on the strength of a registry entry alone.
