Intermediate incubation from about 1 to 3 days

Infections of the large intestine or colon can cause bloody, mucoid diarrhea associated with crampy abdominal pain.

  • Campylobacter, according to CDC data, is the number one cause of foodborne disease in the United States.
  • Shigella spp contaminate food and water and cause dysentery (severe diarrhea often containing mucus and blood).
  • Salmonella infections often occur because of poorly or undercooked cooked, and poor handling of the chicken and eggs. In individuals with weakened immune systems, including the elderly, the infection can enter the bloodstream and cause potentially life-threatening infections.
  • Vibrio parahaemolyticus can contaminate saltwater shellfish and cause a watery diarrhea.

Diarrhea due to small bowel infection tends not to be bloody, but infections may affect both the small and large intestine at the same time.
