Cyclosporiasis is a diarrheal disease caused by the parasite Cyclospora cayetanensis. Infection is often spread by consuming contaminated food and drinks and commonly imported raw fruit and vegetables such as raspberries, blackberries, lettuce, snow peas, and salad herbs.
If you or a loved one contracted Cyclospora, speak with an experienced Cyclospora lawyer to explore your legal right to compensation.
Currently, only one Cyclospora species is known to be associated with syndromes of acute and chronic diarrhea in humans. Cyclospora infections have largely surfaced in people who traveled to countries in tropical and subtropical regions where cyclosporiasis commonly occurs, including:
To reduce the risk of infection, travelers can take precautions. For example, in areas with inadequate hygiene and sanitation, travelers should avoid salads, uncooked vegetables, raw and unpeeled fruits, and unpasteurized fruit juices. It is also important to note that treating water or food by routine sanitizing methods or chemical disinfection is unlikely to kill Cyclospora oocysts.
Cyclosporiasis cases are reported year-round in the U.S. but are most common in the spring and summer months. Here is data for domestically acquired cases between May and August.
This table summarizes U.S. foodborne outbreaks of Cyclosporiasis between 2000 to 2020, the approximate number of cases, as well as the probable source if it was identified.

In 2018, the U.S. Food and Drug Administration (FDA) began using a new method to detect Cyclospora in food. This new testing method was a critical tool used to identify produce that was positive for Cyclospora during 2018 outbreak investigations. It was the first time the FDA was able to confirm the presence of Cyclospora in food since the early 2000s. This significant step forward can lead to better detection and prevention efforts.
Cyclosporiasis is a nationally notifiable disease, which means it is considered to be of great public health importance and state health departments must report confirmed and probable cases to the CDC. As a result, it is your health care provider’s responsibility to report cases of Cyclosporiasis to your state’s department of health, not yours. However, that doesn’t mean you can’t notify your state health agency of your illness.
The Centers for Disease Control and Prevention (CDC) receives timely and frequent reports of cases from states and jurisdictions where the disease is reportable. Currently, 43 states, the District of Columbia, and New York City have passed legislation making Cyclosporiasis a reportable disease. Timely reporting of this illness is critical to preventing and controlling a potential outbreak and allows researchers to identify disease trends.
