Campylobacter Infections

Campylobacter infection is a common foodborne illness typically contracted through contaminated food, water, or contact with infected animal feces.

Overview

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.

Symptoms

Some infected people do not have any symptoms. If you do have symptoms, they start two to five days after you are infected and usually last about one week. Symptoms can include:

  • Diarrhea (which could be bloody)
  • Cramping
  • Abdominal pain
  • Fever
  • Fatigue
  • Nausea and vomiting

Diagnosis and Treatment

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.

Prevention

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.

Frequently Asked Questions

The most common causes are cross-contamination and undercooking. Using the same cutting board or knife for raw poultry and then for ready-to-eat foods like salads or vegetables without washing them in hot, soapy water is a major risk. Additionally, not cooking poultry to a safe internal temperature of 165°F (74°C) as measured by a food thermometer allows the bacteria to survive and cause infection.
Generally, you should stay home until you have been free of diarrhea for at least 48 hours. This is particularly important if you work in food service, healthcare, or childcare, as the bacteria can still be shed in stool after symptoms subside. Check with your employer or local health department for specific clearance requirements, especially if you handle food or care for vulnerable populations.
While symptoms like diarrhea, cramping, and fever are similar to many gastrointestinal illnesses, Campylobacter often presents with bloody diarrhea and more intense abdominal pain. However, it is impossible to self-diagnose based on symptoms alone. A stool culture or PCR test is required for confirmation. If you have bloody stools, high fever, or symptoms lasting more than three days, seek medical evaluation to rule out Campylobacter and other serious pathogens.
You must complete the entire course of antibiotics prescribed by your healthcare provider, even if your symptoms improve before the medication is finished. Stopping early can allow the infection to return or contribute to antibiotic resistance. If you experience severe side effects, contact your doctor immediately for guidance rather than stopping the medication on your own.
