What You Need to Know About the Growing Cyclospora Outbreak (Video)

Summer potlucks and fresh salads are a warm-weather staple, but health officials are urging extra caution at the grocery store right now. According to the latest updates from the Centers for Disease Control and Prevention (CDC) and the Food and Drug Administration (FDA), cases of Cyclospora infection—known as cyclosporiasis (a gastrointestinal illness caused by a microscopic parasite)—have been rising sharply across the country.

The CDC reports over 4,100 laboratory-confirmed domestic cases across 41 states, with 7,400 more cases currently under investigation. A major driver of the recent surge includes a multistate outbreak linked to contaminated shredded iceberg lettuce sourced from Taylor Farms de Mexico, which led to voluntary recalls and nearly 2,000 confirmed illnesses across nine states.

Understanding the Risk

Unlike common bacterial foodborne bugs like E. coli or Salmonella, Cyclospora cayetanensis is a resilient parasite spread when food or water becomes contaminated with microscopic human waste. Once ingested, it causes symptoms like severe, watery diarrhea, loss of appetite, bloating, stomach cramps, and fatigue. Left untreated, these symptoms can persist for weeks or even relapse over time.

What makes Cyclospora especially tricky for home cooks is its resilience. Standard chlorine washes and routine chemical sanitizers commonly used in commercial food processing or household kitchens often fail to eliminate the parasite. Moreover, because produce items like pre-packaged salad mixes or salsas contain ingredients from multiple growers, tracking down the exact origin during an outbreak takes time.

Simple Actions to Protect Your Family

While health agencies work to contain outbreaks and monitor supply chains, you can take practical steps in your own kitchen to minimize your risk:

• Check for Recalls: Stay updated on current FDA food safety alerts. Immediately throw away or return any recalled produce, such as affected Taylor Farms iceberg lettuce.
• Wash Thoroughly Under Running Water: Always rinse fresh fruits and vegetables under clean, running tap water before eating, peeling, or cutting—even if the package is labeled as “pre-washed”.
• Scrub Firm Produce: Use a clean vegetable brush to scrub firm-skinned produce like melons and cucumbers under running water.
• Skip Soaps and Bleach: Do not use soap, detergent, bleach, or chemical produce washes. They are not proven effective against Cyclospora and can leave harmful chemical residues on your food.
• Cook When Possible: Heating produce to an internal temperature of at least 158°F (70°C) kills the parasite. If you are preparing meals for young children, elderly family members, or immunocompromised individuals, cooked dishes are the safest choice.
• Practice Clean Hygiene: Wash your hands with warm water and soap for at least 20 seconds before and after handling raw produce. Keep cutting boards, countertops, and utensils thoroughly scrubbed with hot, soapy water.

If you or a family member experiences prolonged stomach trouble after eating fresh produce, reach out to a healthcare provider. Testing specifically for Cyclospora requires a targeted lab test, and effective prescription antibiotics are available to help you recover quickly.
