Factors That Increase Your Risk for Food Poisoning

Anyone can get food poisoning, but certain groups of people are more likely to get very sick from food poisoning. If you have one of these factors, your body may not be able to fight germs and sickness as effectively.
Factors That Increase Risk for Food Poisoning

As people age, their immune systems and organs don’t recognize and get rid of harmful germs as well as they once did. This increases the chance they’ll get sick from food poisoning. Nearly half of people aged 65 and older who have a lab-confirmed foodborne illness from Salmonella, Campylobacter, Listeria or E. coli are hospitalized.

Young children’s immune systems are still developing, so their body’s ability to fight germs and sickness isn’t as strong. Food poisoning can be particularly dangerous for them because illness can lead to diarrhea and dehydration. Children younger than 5 are three times more likely to be hospitalized if they get a Salmonella infection. Kidney failure strikes 1 out of 7 children under age 5 who are diagnosed with E. coli O157 infection.

Having a weakened immune system may make it harder to fight germs and sickness effectively. Weakened immune systems may be due to diabetes, liver disease, kidney disease, alcoholism, HIV, autoimmune disorders such as lupus, or receiving chemotherapy or radiation therapy. For example, people on dialysis are 50 times more likely to get a Listeria infection.

If you or someone you care for has one of these factors, it’s especially important to take steps to prevent food poisoning, know which foods are more often linked with illness, and learn what foods are safer.
