Cases of cyclosporiasis are on the rise across the United States, with an ongoing multi-state outbreak that has resulted in two reported deaths. As this foodborne illness continues to affect more people, it’s important to understand how it spreads, recognize the signs and symptoms, know when to seek medical care, and take steps to reduce your risk. This week’s Friday Five features five key facts from the American Medical Association (AMA) to help you stay informed, protect yourself and your family, and reduce the risk of illness.
Know How Cyclosporiasis Spreads
Cyclosporiasis is a gastrointestinal illness caused by a tiny parasite called Cyclospora. You can become infected with Cyclospora when you eat food or drink water that is contaminated with human feces. Cyclosporiasis does not spread from person to person. However, you can be infected with the parasite more than once.
Recognize the Symptoms
Symptoms of cyclosporiasis include watery diarrhea, fatigue, and loss of appetite and typically begin about one week after becoming infected. Not everyone will have symptoms but many people can get very sick, especially anyone who is immunocompromised, the elderly, and children.
Seek Medical Care, Stay Hydrated, and Rest if You Have Symptoms
Antibiotics are available to treat cyclosporiasis. If you are experiencing symptoms, it is important to get rest, drink plenty of fluids, and talk with your doctor or other healthcare professional to help you determine the best course of action. You may need to request testing for Cyclospora as routine stool tests don’t always screen for this parasite. Without treatment, symptoms can last anywhere from a few days to a month or longer.
Stay Informed about Food Recalls
Recent outbreaks of cyclosporiasis have been linked to eating or handling fresh produce, including iceberg lettuce. Do not consume any recalled foods, particularly iceberg lettuce sourced from central Mexico—when in doubt throw it away or return it. Stay up to date on food recalls and outbreaks at www.foodsafety.gov.
Take Steps to Avoid Illness
Reduce your risk of getting sick from Cyclospora by following these tips for safe food handling:
- Wash your hands and all produce thoroughly under running water before eating, cutting, or cooking—including produce labeled as pre-washed,
- Cook produce to a temperature of at least 158 °F (70°C) as cooking can kill the parasite but washing alone cannot guarantee Cyclospora removal,
- Wash any items or surfaces that may have come in contact with recalled produce with hot soapy water,
- Scrub firm fruits and vegetables, such as melons and cucumbers, with a clean produce brush,
- Cut away the outer layers or any damaged or bruised areas of fruits and vegetables before preparing and eating.
