Serious Health Problems and Long-Term Effects From Food Poisoning

Most people have mild illnesses, but some infections spread by food are serious or even life-threatening. Some people may need to be hospitalized, and some illnesses lead to other health problems, including:

Meningitis
Kidney damage
Hemolytic uremic syndrome (HUS), which can cause kidney failure
Arthritis
Brain and nerve damage

For some people, these health problems can last for weeks or months after recovering from the foodborne illness. For others, they never go away.
