Newtown Health District is elevating its consistent messaging regarding food safety as it shares CT Department of Public Health’s (CT DPH) reporting and recommendations regarding the increase in cyclosporiasis cases.

Nationally, cyclosporiasis has been reported in 17 states, with the most significant cluster occurring in Southeast Michigan. The Michigan Department of Health and Human Services reported 1562 cases as of July 10. No specific produce grower, supplier, or food item has been identified as the source of that outbreak to date. Historically, US outbreaks of cyclosporiasis have been linked to fresh produce, including bagged salad mixes, fresh cilantro, fresh basil, raspberries, snow peas, and green onions.

CT DPH has confirmed 35 cases of cyclosporiasis as of July 13, nearly doubling the case count from the same time last year. Cyclosporiasis is an intestinal illness caused by the Cyclospora parasite, typically resulting in frequent, watery diarrhea, though it is treatable with antibiotics, rest, and adequate hydration. While authorities have not identified a specific source for the Connecticut cases, they are actively investigating and advising residents to follow safety precautions, especially those at higher risk such as young children, older adults, and individuals with weakened immune systems.

To reduce the risk of infection, health officials recommend the following:

*Wash all fresh produce under clean running water, even if you intend to peel it.

*Select whole heads of lettuce instead of pre-washed, bagged salad mixes; remove and discard the outer two to three layers of leaves, and wash the inner leaves under running water.

*Wash cilantro, basil, and green onions thoroughly under running water, ensuring leaves are separated; these items are safest when cooked.

*Heat produce to at least 158°F (70°C) whenever possible, as this temperature kills the parasite.

Newtown Health District also encourages residents to follow general food safety reminders:

Wash hands with soap and water before and after handling or preparing food.

*Scrub firm fruits and vegetables, such as cucumbers and melons, with a clean produce brush.

*Wash and sanitize all cutting boards, utensils, and surfaces before and after food preparation.

*Refrigerate fruits and vegetables immediately after they have been peeled, cut, or cooked.

CT DPH Commissioner Manisha Juthani, MD, said, "Connecticut's surveillance system is doing exactly what it should: identifying cases, tracking exposures, and helping us stay ahead of this illness … We want to reassure residents that cyclosporiasis is treatable and we have not identified a Connecticut-specific source. At the same time, we encourage everyone, especially those at higher risk, to take a few simple precautions with fresh produce this summer. Washing your produce thoroughly, buying whole heads of lettuce instead of pre-washed bagged varieties, and cooking herbs and leafy greens when possible are steps that go a long way."

People experiencing sudden and persistent diarrhea, particularly watery or explosive diarrhea, are encouraged to contact their healthcare provider. Cyclosporiasis is treated with antibiotics along with rest and adequate fluids to maintain hydration.
