Pathogens & Protocols

Why it's a Threat

Campylobacter is the most common bacterial cause of diarrhea in the United States; over 2 million cases are reported each year. Although Campylobacter doesn't commonly cause death, it is estimated that approximately 100 persons with Campylobacter infections die each year.


Gram-negative bacteria, S-shaped or spiral rods, approximately 0.5 micron wide and 2 microns long. A polar tail at one or both ends propels the bacteria through liquid.


Thrives in birds; spreads through raw and undercooked poultry, raw milk, and untreated water.


  • Cook all poultry products thoroughly. Make sure that the meat is cooked throughout (no longer pink) and any juices run clear. All poultry should be cooked to reach a minimum internal temperature of 165 °F.
  • If you are served undercooked poultry in a restaurant, send it back for further cooking.
  • Wash hands with soap before preparing food. More


Campylobacter's growing resistance to antibiotics may complicate treatment in the future.
