Individuals who are at risk

Whether you become ill after eating contaminated food depends on the organism, the amount of exposure, your age and your health. High-risk groups include:

  • Older adults. As you get older, your immune system may not respond as quickly and as effectively to infectious organisms as when you were younger.
  • Pregnant women. During pregnancy, changes in metabolism and circulation may increase the risk of food poisoning. Your reaction may be more severe during pregnancy. Rarely, your baby may get sick, too.
  • Infants and young children. Their immune systems haven’t fully developed.
  • People with chronic disease. Having a chronic condition — such as diabetes, liver disease or AIDS — or receiving chemotherapy or radiation therapy for cancer reduces your immune response.
