The known routes of Campylobacter transmission include fecal-oral, person-to-person sexual contact, unpasteurized raw milk and poultry ingestion, and waterborne (ie, through contaminated water supplies). Exposure to sick pets, especially puppies, has also been associated with Campylobacter outbreaks.

Transmission of Campylobacter organisms to humans usually occurs via infected animals and their food products. Most human infections result from the consumption of improperly cooked or contaminated foodstuffs. Chickens may account for 50-70% of human Campylobacter infections. Most colonized animals develop a lifelong carrier state.
