Long-Term Consequences of Foodborne Illness

In 2008, an Associated Press article featuring one of Stop’s volunteer advocates, Alyssa Chrobuck, highlighted the need for increased awareness and research of the long-term health consequences of foodborne illness. At age 5, Alyssa was hospitalized as a result of E. coli poisoning, the source of which was tainted hamburger from a fast food restaurant.

Alyssa, now an adult, suffers from a myriad of health problems including high blood pressure, chronic colon inflammation, and endometriosis.

Included in the article was this statement from Dr. Robert Tauxe of the Centers for Disease Control and Prevention, “Folks often assume once you’re over the acute illness, that’s it, you’re back to normal and that’s the end of it. [The long-term consequences] are an important but relatively poorly documented, poorly studied area of foodborne illness.”

Long-Term Consequences Research

Stop Foodborne Illness has been engaged in research of long-term consequences since 2008.

Chronic diseases such as Guillain-Barré (Ghee-yan Bah-ray) Syndrome (GBS) and Irritable Bowel Syndrome (IBS) have evidence of a well-established correlation with prior diagnosis of foodborne illness. While these correlations are established, research in this field is still emerging. There are many unknowns and STOP has an obligation to add to the collective knowledge.

We are a resource for those in-crisis and post-crisis, and researching long-term consequences allows us to effectively assist our constituent advocates.

If you were previously diagnosed with a foodborne illness, and are interested in participating in future research studies or have any questions about potential participation, please contact Stanley at

Kidney Failure/HUS

Hemolytic-uremic syndrome (HUS) is a serious illness that usually occurs when an infection in the digestive system produces toxic substances that destroy red blood cells, causing kidney injury. HUS may occur after infection with some kinds of E. coli bacteria. Those who have suffered from HUS may be at risk for other kidney-related problems later in life. These annual checkups should be performed:
  • Blood Pressure — scarring of the kidney tissue from HUS could cause high blood pressure early in life
  • Urine Exam — elevated protein levels in the urine may be indicative of kidney damage
  • Blood Test — to further measure kidney function

Chronic Arthritis

A small number of persons with CampylobacterShigella, or Salmonella infections develop pain in their joints, irritation of the eyes, and painful urination called Reactive Arthritis. This arthritic inflammation can last for months or years and can lead to chronic arthritis, which is difficult to treat.

Brain and Nerve Damage

Listeria infections can lead to meningitis, an inflammation of the membranes surrounding the brain. If a newborn infant or fetus is infected with Listeria, long-term consequences may include mental retardation, seizures, paralysis, blindness, or deafness.

Foodborne bacterial infections can also precipitate Guillain-Barré syndrome — a rare disorder that affects the nerves of the body. This occurs when a person’s immune system attacks the body’s own nerves.

It can result in paralysis that lasts several weeks and usually requires intensive care. As many as 40% of Guillain-Barré syndrome cases in the U.S. may be triggered by a Campylobacter infection.

If you or a loved one has been affected by any of these long-term complications, we would like to hear your story.
