Decatur, IL (WAND) – As of July 13, Illinois had 194 reported cases of cyclospora. Local doctors say Illinois is among the top states affected by a cyclosporiasis outbreak this season.
Cyclosporiasis is a parasitic illness linked to fresh fruits and vegetables. Dr. Anna Richie, clinical director of Memorial Urgent Care, said the parasite is a recurring seasonal concern — but this year stands out.
“This year we’re seeing a lot more numbers and a bigger outbreak than we have in previous years,” said Richie. “This is a parasite that gets in the little crevices of, like raspberries and lettuce, onions, cilantro and basil.”
Dr. Jignesh Modi, an infectious disease physician at HSHS St. Mary’s Hospital, said the parasites are typically found on the outer surface of fruits and vegetables and are not eliminated by simple washing, sprays, chemicals, or bleach.
“The water source that they use to fertilize or to irrigate the plantation — that’s where these parasites contaminate the food product,” Modi said. “If there is a fruit or vegetable that can be peeled off, take the peel off. That kind of protects you.”
Both doctors said to choose products like a whole head of lettuce over chopped, bagged lettuce, so you can remove the outer layers and clean the leaves well. Cooking the produce will also kill the parasite, according to both doctors.
Richie said symptoms typically begin several days to about a week after ingesting the parasite — not the following day. Symptoms can include diarrhea, bloating, nausea and a low-grade fever.
“What’s different about this compared to like a normal virus is that it can last weeks to even a month or more,” Richie said.
Dr. Richie said there is an antibiotic available for cyclosporiasis, so if you start feeling symptoms, connect with your doctor.
