Key takeaways
This foodborne illness affects over 1.3 million Americans annually, with Campylobacter jejuni being the most common strain found in raw poultry (affecting up to 70% of chicken products).
Symptoms typically appear 2-5 days after exposure and include watery diarrhea that may turn bloody, along with fever reaching 104Β°F and severe abdominal cramping lasting 3-7 days.
Cross-contamination poses the highest riskβusing the same cutting board for raw chicken then vegetables can spread millions of bacteria, even after rinsing with water.
Most cases resolve without antibiotics, but azithromycin (500mg daily for 3 days) may be prescribed for immunocompromised patients or those with bloody stools lasting over 48 hours.
Cooking poultry to an internal temperature of 165Β°F kills the bacteria instantly, while freezing only reduces but doesn't eliminate contaminationβproper cooking remains essential.
Campylobacteriosis is a common bacterial infection that affects the digestive system. It is caused by bacteria called campylobacter, which can be found in contaminated food and water. This infection is more prevalent in infants, children, and men, and is more likely to occur during the summer months.
Symptoms of Campylobacteriosis
The symptoms of campylobacteriosis usually appear within a couple of days after consuming contaminated food or water. These symptoms may include:
- Diarrhea (sometimes bloody)
- Nausea
- Vomiting
- Abdominal cramps
- Bloating
- Fever
In some cases, people may not experience any symptoms at all.
Causes of Campylobacteriosis
Campylobacteriosis is primarily caused by consuming undercooked poultry or food that has come into contact with raw or undercooked poultry. The bacteria can also be found in unpasteurized milk and contaminated water. It may be transmitted by infected animals (dogs, cats, livestock). In developing countries, the bacteria may be present in water and sewage systems.

Diagnosing Campylobacteriosis
To diagnose campylobacteriosis, your doctor may request a stool sample, which will be sent to a lab for testing. In rare cases, a blood test may be ordered, but the results can take up to two weeks.
Treating Campylobacteriosis
Most people recover from campylobacteriosis without the need for medication or special treatments. It is essential to stay hydrated by drinking plenty of fluids during the illness. In some cases, particularly for those with weakened immune systems, antibiotics such as azithromycin, ciprofloxacin, or levofloxacin may be prescribed.
Antibiotic Resistance and Campylobacteriosis
Some strains of campylobacter have developed resistance to antibiotics, making the infection harder to treat and potentially leading to more severe illness and longer recovery times.
Preventing Campylobacteriosis
To prevent campylobacteriosis, it is crucial to follow proper food safety practices:
- Cook poultry thoroughly to an internal temperature of at least 165Β°F (74Β°C)
- Wash your hands before cooking and after handling raw poultry or meat
- Use separate cutting boards, utensils, and cooking surfaces for raw meat and other foods
- Wash your hands after touching pets or their feces
- Ensure that anyone with diarrhea washes their hands thoroughly
If you have campylobacteriosis, it is essential to stay home from work or school and avoid public places until your diarrhea has resolved to help prevent the spread of the infection.
For more information on campylobacteriosis and food safety, visit the Centers for Disease Control and Prevention (CDC), the World Health Organization (WHO), and the FoodSafety.gov websites.
The Bottom Line
This common bacterial infection usually clears within a week through rest and hydration, but proper food handling is your best defense against infection. Always use separate cutting boards for raw meat and verify poultry reaches 165Β°F with a meat thermometer. If you're experiencing persistent bloody diarrhea or high fever, Doctronic can help you determine if you need immediate medical attention.
