As the summer heat rises, so do concerns about a particular intestinal infection that has been making headlines: Cyclosporiasis. This parasitic infection, caused by the Cyclospora cayetanensis parasite, has been causing explosive diarrhea and severe gastrointestinal upset across the United States. With over 5,000 cases reported in more than 30 states as of July 14, the question on everyone's mind is: What foods should you avoid to prevent this illness?
The Parasite and Its Spread
Cyclosporiasis is not a new infection, but it typically peaks in the summer. What's unusual about the current outbreak is the rapid increase in cases and the high numbers reported, especially in Michigan, where over half of U.S. cases have been reported. The parasite spreads through contaminated food or water, and past outbreaks have been linked to raw produce.
The Mystery of the Outbreak
Health officials are still investigating the source of the outbreak, with lettuce or salad greens identified as a potential culprit in Michigan. However, it's unclear if the outbreaks in different states are connected, and other food items cannot be ruled out. The true number of infections is likely higher than reported, as many people with diarrhea do not seek medical attention or get tested for Cyclospora.
Avoiding Contaminated Produce
Given the uncertainty around the source, it's impossible to know which produce items are safe. However, experts advise against panicking. Most fresh fruits and vegetables are not linked to the outbreak and are not more likely to cause illness. Cooking food to at least 158 degrees Fahrenheit is the best way to protect yourself, as freezing can also eliminate Cyclospora. Washing produce thoroughly can reduce the risk, but it won't guarantee safety.
Precautions for Affected Areas
For those living in affected counties in Michigan, the state health department recommends the following precautions:
- Purchase whole heads of lettuce instead of pre-washed and packaged salad greens.
- Throw away the outer two to three layers of the leaves.
- Wash the inner leaves with clean, running water.
- Cook greens to a temperature of at least 158 degrees Fahrenheit.
Preventing Cyclospora Infection
In addition to cooking, there are other ways to be proactive. Wash your hands well with soap before and after handling raw produce. Scrub all fresh fruits and vegetables with a produce brush under clean, running water, and remove the outer layer of leaves or the peel if possible. Cut or peel off damaged areas of produce before eating. People with weakened immune systems may need to take extra precautions and consult their doctor.
Conclusion
While the Cyclospora outbreak is concerning, it's important to remember that most fresh produce is not linked to the outbreak. By taking simple precautions and staying informed, we can enjoy the summer's bounty without fear. As experts continue to investigate the source, we can take comfort in the knowledge that we can protect ourselves and our loved ones from this parasitic infection.
