Health officials are reporting a sharp increase in cyclosporyiasis cases on Florida's Suncoast, prompting renewed reminders about food safety as families continue shopping for fresh produce during the summer.

The latest Florida Department of Health report shows 12 confirmed or probable cases in Sarasota and Manatee counties through Aug. 1, eight in Manatee County and four in Sarasota County. That's up from just four combined cases reported through July 18.

The increase comes as the Centers for Disease Control and Prevention continues investigating a nationwide outbreak involving thousands of illnesses, including a multistate outbreak linked to recalled iceberg lettuce.

Cyclospora is a microscopic parasite that spreads when people consume food or water contaminated with feces containing the parasite.

Symptoms usually develop one to two weeks after exposure and may include:

  • Prolonged watery diarrhea that may come and go
  • Stomach cramps
  • Fatigue
  • Nausea
  • Loss of appetite
  • Weight loss
  • Bloating
  • Vomiting
  • Low-grade fever

Not everyone who becomes infected develops symptoms, and many people recover without seeking medical care. However, untreated illness can last for days or even weeks, and diarrhea can lead to dehydration.

People with weakened immune systems or underlying medical conditions may be at greater risk for severe illness.

What Tampa Bay residents can do

Whether preparing everyday meals or stocking up for hurricane season, following safe food-handling practices can help reduce the risk of infection.

  • Wash your hands with soap and water for at least 20 seconds before and after handling food and after using the restroom.
  • Wash cutting boards, utensils and countertops between preparing different foods.
  • Thoroughly rinse fruits and vegetables under clean running water before eating or preparing them.
  • Choose whole heads of lettuce instead of prepackaged salad mixes when possible.
  • Remove and discard the outer two to three leaves of lettuce before washing the remaining leaves under running water.
  • Cook foods that can be heated to an internal temperature of at least 158 degrees Fahrenheit (70 degrees Celsius).
  • Store food at safe temperatures and follow proper refrigeration practices.

Health officials note that Cyclospora is resistant to routine chemical disinfection, meaning washing produce alone cannot guarantee the parasite is removed.

Bottom line

Disaster preparedness isn't just about flashlights and hurricane supplies—it also includes protecting your family's health. Safe food handling, especially during hurricane season when refrigeration and food storage can become challenging, is an important part of staying resilient.

Anyone experiencing persistent diarrhea or other symptoms of cyclosporiasis should contact a health care provider. The illness is treatable with antibiotics, and staying hydrated is important for anyone experiencing frequent diarrhea.
