If you've seen recent news about Cyclospora infections across the United States, you may be wondering whether your family's favorite fruits and vegetables are still safe to eat. The good news is that while Cyclospora infections can make people quite sick, there are practical steps families can take to lower their risk.
What is Cyclospora?
Cyclospora is a microscopic parasite that causes an intestinal illness called cyclosporiasis. People become infected by eating food or drinking water contaminated with the parasite. In the United States, outbreaks have most often been linked to fresh produce such as leafy greens, herbs, berries, and other fruits and vegetables. Health officials are currently investigating a rise in cases in multiple states, although the exact food source has not yet been identified.
Unlike many stomach viruses, Cyclospora does not usually spread directly from one person to another because the parasite needs time in the environment before it becomes infectious.
What are the symptoms?
Symptoms typically begin about one week after exposure, although they can appear anywhere from 2 days to 2 weeks later. Common symptoms include:
- Frequent watery diarrhea that may last for weeks
- Stomach cramps
- Bloating and gas
- Nausea
- Fatigue
- Loss of appetite
- Weight loss
- Low-grade fever (sometimes)
Without treatment, symptoms may come and go for several weeks or even longer.
Are children at risk?
Yes. Anyone can become infected with Cyclospora, including children. While many healthy children recover with appropriate treatment and hydration, prolonged diarrhea can increase the risk of dehydration—especially in infants and young children. Contact your child's healthcare provider if your child has:
- Diarrhea lasting more than a few days
- Signs of dehydration (dry mouth, decreased urination, dizziness, or unusual sleepiness)
- Blood in the stool
- High fever
- Severe abdominal pain
A healthcare provider can determine whether testing or treatment is needed. Cyclospora is typically treated with prescription antibiotics.
How can parents help prevent Cyclospora?
Although no prevention method is perfect, these habits can significantly reduce your family's risk:
- Wash fresh produce thoroughly
- Rinse fruits and vegetables under running water before eating, peeling, or cutting them. Even produce with a peel should be washed first to prevent transferring germs to the inside when slicing.
- Wash your hands
- Use soap and water before preparing food, before eating, and after using the bathroom or changing diapers.
- Keep your kitchen clean
- Wash cutting boards, knives, and countertops after preparing fresh produce to reduce cross-contamination.
- Refrigerate perishable foods promptly
- Proper food storage helps reduce the growth of many harmful microorganisms, even though refrigeration alone does not eliminate Cyclospora.
- Stay informed about recalls
If investigators identify a contaminated food product, public health agencies will issue recalls or consumer advisories.
Should families stop eating fresh produce?
No. Fruits and vegetables remain an important part of a healthy diet. Current investigations have not identified a single food responsible for the recent increase in cases, so experts continue to recommend eating plenty of produce while following safe food-handling practices.
The Bottom Line
Recent news about Cyclospora can sound alarming, but there is no need to panic. Most infections can be prevented with good food safety habits, and effective treatment is available when the illness is diagnosed. As parents, the best approach is simple: wash produce, practice good hand hygiene, keep your kitchen clean, and contact your healthcare provider if someone in your family develops prolonged diarrhea. Staying informed—and following everyday food safety practices—is one of the best ways to keep your family healthy this summer.
