As summer brings more fresh fruits and vegetables to our tables, it’s a good time to review important food safety practices that can help protect you and your family from foodborne illnesses such as cyclosporiasis. Cyclospora is a microscopic parasite that can contaminate food or water and cause an intestinal illness known as cyclosporiasis. People become infected by consuming contaminated food or water. Symptoms typically begin about one to two weeks after exposure.
What Is Cyclosporiasis?
Cyclosporiasis is a diarrheal illness caused by the parasite Cyclospora cayetanensis. Common symptoms include:
- Watery diarrhea
- Stomach cramps
- Bloating
- Increased gas
- Nausea
- Loss of appetite
- Weight loss
- Fatigue
Some people may also experience vomiting or a low-grade fever. Symptoms can last for days or even weeks if left untreated, and some people experience symptoms that improve and then return.
Is There an Outbreak in California?
The California Department of Public Health (CDPH) reports that California is not currently experiencing a known outbreak of cyclosporiasis, and no California cases have been linked to the multistate outbreaks being investigated elsewhere in the United States. From January through June 2026, California reported 41 provisional cases, compared to 80 cases during the same period in 2025. Most California cases are associated with international travel.
While the risk remains low, following safe food handling practices can help reduce your chances of becoming sick.
Protect Yourself with the CDC’s Wash, Prepare, Store Method
The Centers for Disease Control and Prevention (CDC) recommends following these simple steps when handling fresh produce.
Wash
- Wash your hands with soap and water before and after handling or preparing fresh fruits and vegetables.
- Wash fruits and vegetables thoroughly under running water before eating, cutting, or cooking them.
- Wash produce even if it is labeled “pre-washed.”
Prepare
- Scrub firm fruits and vegetables, such as melons and cucumbers, using a clean produce brush.
- Cut away any damaged or bruised areas before preparing and eating produce.
Store
- Refrigerate cut, peeled, or cooked fruits and vegetables as soon as possible, ideally within two hours.
These simple habits can help reduce the risk of foodborne illness and support safer food preparation at home.
When Should You Contact a Healthcare Provider?
If you experience persistent diarrhea, stomach cramps, bloating, nausea, or other gastrointestinal symptoms, contact your healthcare provider. Diagnosing cyclosporiasis may require specific testing of stool samples because Cyclospora is not always detected through routine testing. Treatment may include antibiotics prescribed by a healthcare provider.
A Simple Reminder for a Healthier Summer Fresh produce is an important part of a healthy diet. Taking a few extra moments to wash, prepare, and store fruits and vegetables properly can go a long way toward protecting your health and the health of your family. By following food safety best practices, you can continue to enjoy the benefits of fresh produce while reducing your risk of foodborne illness.
