Food poisoning linked to autoimmune diseases in Americans

Food poisoning, caused by bacteria or germs in contaminated food, can lead to serious health issues beyond initial symptoms. Each year, around 48 million Americans suffer from foodborne illnesses, resulting in about 3,000 deaths. Many cases are linked to norovirus, a highly contagious pathogen. Recent research indicates that foodborne illnesses may also trigger autoimmune diseases. Autoimmune diseases occur when the body’s immune system attacks its own healthy cells. The Centers for Disease Control and Prevention reports that more than 200,000 Americans develop long-term effects from food poisoning each year. This can lead to conditions such as irritable bowel syndrome and reactive arthritis, which can cause significant discomfort. Foodborne pathogens like E. coli, Salmonella, and Campylobacter are commonly associated with these long-term issues. For example, Campylobacter, often found in undercooked poultry, can trigger Guillain-Barré syndrome, a severe condition that may lead to paralysis. Research also connects some foodborne pathogens to risks for diseases like Alzheimer’s and Parkinson’s. Certain groups, including young children, the elderly, and pregnant women, are more vulnerable to foodborne illnesses. To reduce the risk, health experts recommend cooking food thoroughly, washing hands and surfaces, and keeping raw food separate from ready-to-eat items. If someone suspects they have a foodborne illness, they should contact their local health department and track what they have eaten to help with diagnosis.
