Frequent use of AFFF: Civilian & military firefighters may develop ulcerative colitis

By Michael Bartlett on May 06th, 2025 in

Ulcerative colitis (UC) is a type of chronic inflammatory bowel disease (IBD) that affects the lining of the colon and rectum. The exact causes remain unknown, but ulcerative colitis is typically associated with multiple risk factors like age, genetics, gut microbiome, and lately, frequent use of aqueous film-forming foam (AFFF), which contains PFAS.

PFAS or per- and polyfluoroalkyl substances are a group of more than 15,000 man-made chemicals used for various purposes, including firefighting. These chemicals are a key ingredient of AFFF. AFFF currently faces intense scrutiny due to health concerns surrounding PFAS exposure.

Studies: PFAS exposure is associated with higher chances of developing ulcerative colitis

Several scientific studies have found the connection between PFAS and higher chances of developing ulcerative colitis. Research from the National Academies Report acknowledges the presence of evidence suggesting PFOS (perfluorooctanesulfonic acid) can contribute to the development of gastrointestinal (GI) inflammation, potentially leading to ulcerative colitis. PFOS is a type of PFAS commonly used in older versions of AFFF.

Furthermore, a study published in Environmental Research showed that individuals with ulcerative colitis had higher levels of perfluorooctanoic acid (PFOA) in their blood. Likewise, according to another study from the Journal of Crohn's and Colitis, those with Crohn's Disease and ulcerative colitis have elevated concentrations of PFAS in their system.

Firefighters are at a higher risk of developing ulcerative colitis

Around 600,000 to 900,000 Americans live with ulcerative colitis, but because of the frequent use of AFFF, firefighters are more likely to develop this lifelong condition. According to the National Institute of Diabetes and Digestive and Kidney Diseases, an individual with ulcerative colitis may experience the following symptoms:

  • Diarrhea
  • Rectal bleeding
  • Cramps or pain in the abdomen
  • Fever
  • Dehydration
  • Passing mucus or pus with stool

With early detection, these symptoms can be managed, and firefighters showing the above-mentioned signs should consult a physician as soon as possible.
