Campylobacter Infection and Animals

What is Campylobacter infection (campylobacteriosis)?

Important Tip!

Protect yourself against getting Campylobacter from animals. Simply wash your hands with running water and soap after any contact with animals and animal feces (stool).


Campylobacteriosis is a bacterial disease caused by Campylobacter jejuni or Campylobacter coli. Campylobacter usually causes a mild to severe infection of the gastrointestinal system, including watery or bloody diarrhea, fever, abdominal cramps, nausea, and vomiting. A rare complication of Campylobacter infection is Guillain-Barre syndrome, a nervous system disease that occurs approximately 2 weeks after the initial illness develops.

Can animals transmit Campylobacter to me?

bacteria responsible for campylobacteriosis
Sometimes, yes, animals can spread Campylobacter to humans. Most people get campylobacteriosis from contaminated food. However, animals can have Campylobacter in their feces (stool). If people touch contaminated feces, they can get sick. Animals that may carry Campylobacter in their feces include farm animals, cats, and dogs. Animals do not have to be ill to pass Campylobacter to humans. People with compromised immune systems, including those undergoing treatments for cancer, organ transplant patients, and people with HIV/AIDS, have a higher risk than others of getting Campylobacter infection from food and animals.
