Why are older adults more susceptible to foodborne illness?
Everyone’s health is different, including his or her ability to fight off disease. But immune systems weaken as we age. In addition, stomach acid also decreases as we get older — and stomach acid plays an important role in reducing the number of bacteria in our intestinal tracts — and the risk of illness. Plus underlying illnesses such as diabetes, some cancer treatments, and kidney disease may increase a person’s risk of foodborne illness.
