The recent surge in cyclosporiasis cases in Pennsylvania and New Jersey has raised concerns among public health experts. This intestinal parasite, which can cause explosive diarrhea, has been linked to imported produce, particularly basil, cilantro, raspberries, and snow peas. While the disease is not typically life-threatening, its impact on individuals with weakened immune systems can be severe. The time between infection and symptom onset is approximately one week, and symptoms can last anywhere from a few days to a month or longer if left untreated. The Pennsylvania Department of Health has recorded 28 cases in 2026, with 14 in Southeastern Pennsylvania, compared to 40 cases in 2025 and 87 cases in 2024. Despite the rising numbers, no deaths have been attributed to cyclosporiasis this year. The CDC emphasizes that the current wave of cases is not a single, multistate outbreak, but the increasing trend is still a cause for concern. The parasite is endemic in tropical and subtropical regions, but people in other areas can contract it through contaminated food or water. To prevent cyclosporiasis, the CDC recommends washing hands with soap and water before and after handling raw fruits and vegetables, as well as rinsing produce under running water and refrigerating cut, peeled, or cooked produce promptly. While routine disinfecting may not be effective in endemic areas, safe food preparation practices are crucial in preventing the spread of the parasite.
