Campylobacter causes an estimated 1.5 million illnesses each year in the United States.

Most illnesses likely occur due to eating raw or undercooked poultry, or to eating something that touched it. Some are due to contaminated water, contact with animals, or drinking raw (unpasteurized) milk.

Although people with Campylobacter infection usually recover on their own, some need medical treatment.
