Up to 200 cases of cyclosporiasis have been reported across New Jersey amid a widespread nationwide outbreak, according to federal health officials.

Cyclosporiasis is a foodborne illness caused by the Cyclospora parasite and is typically spread through contaminated food or water, including raw produce such as berries, herbs and salad mixes.

Symptoms can include severe diarrhea, stomach cramps, bloating, loss of appetite, weight loss and fatigue. Symptoms generally begin about a week after infection and, without treatment, can persist for a month or longer.

More than 9,400 cases have been reported nationwide. Two deaths involving people with serious underlying health conditions have also been linked to Cyclospora infections in Michigan.

Health officials are urging residents to wash their hands frequently and thoroughly rinse fruits and vegetables before eating them. Anyone experiencing persistent diarrhea or severe symptoms, particularly signs of dehydration, should contact a health care provider.
