Long-Term Effects
One in six Americans will get sick from food poisoning this year. That’s about 48 million people. Most of them will recover without any lasting effects from their illness. For some, however, the effects can be devastating and even deadly.
Here are some serious effects associated with several common types of food poisoning.
Kidney failure
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.
HUS is most common in children. In fact, it is the most common cause of acute kidney failure in children.
Chronic arthritis
A small number of persons with Shigella or Salmonella infection develop pain in their joints, irritation of the eyes, and painful urination. This is called reactive arthritis. It can last for months or years, and can lead to chronic arthritis, which is difficult to treat. Persons with Campylobacter infections may also develop chronic arthritis.
Brain and nerve damage
A Listeria infection can lead to meningitis, an inflammation of the membranes surrounding the brain. If a newborn infant is infected with Listeria, long-term consequences may include mental retardation, seizures, paralysis, blindness, or deafness.
Guillain-Barré syndrome is a 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 percent of Guillain-Barré syndrome cases in this country may be triggered by an infection with Campylobacter.
Death
In the United States, approximately 3,000 people die each year of illnesses associated with food poisoning. Five types of organisms account for 88 percent of the deaths for which the cause is known: Salmonella, Toxoplasma, Listeria, norovirus, and Campylobacter.
Other types of foodborne illness may cause death as well. For example, some Vibrio infections (usually associated with eating raw shellfish) may infect the bloodstream and cause a severe, life-threatening illness. About half of these infections are fatal, and death can occur within two days.
