Scientific classification

Campylobacteriosis is a gastrointestinal tract infection caused by Campylobacter. It causes inflammation, sometimes bloody diarrhea, cramps, fever, and pain.[2][3]

Campylobacteriosis is more common during the summer months. It also appears to be more common in males than females. It is caused by eating contaminated food or drinking contaminated water. Eating raw meat or undercooked poultry, and raw dairy products are common causes.[3]

In January 2013, the UK's Food Standards Agency warned that two-thirds of all raw chicken bought from UK shops was contaminated with Campylobacter.[4] It affects about half a million people annually and kills about 100.[5]
