Parasite Outbreak Causes More Than 1,400 Cases of Diarrhea Across Several States

A parasite outbreak causing severe diarrhea has sickened more than 1,400 people across several states, with health officials warning residents to take precautions when handling food and using recreational water.

The outbreak is being linked to cyclosporiasis, an illness caused by a microscopic parasite called cyclospora. Michigan has reported more than 1,200 cases, while Ohio has reported nearly 200 cases. Other states, including New York, Illinois, Indiana, North Carolina and Texas, have also seen increases.

More than 40 people have been hospitalized.

Health experts say cyclosporiasis can cause watery diarrhea, stomach cramps and bloating. Unlike some stomach illnesses that last only a few days, symptoms from this parasite can continue for weeks or even months.

Investigators have not yet identified the source of the current outbreak, but past cases have been connected to contaminated produce and water.

Health officials say cyclospora does not typically spread directly from person to person. People can become infected by consuming contaminated food or water, including some recreational water sources.

Experts recommend cooking fruits and vegetables when possible, as heating food to an internal temperature of at least 158 degrees Fahrenheit can kill the parasite.

For foods that are eaten raw, such as salad greens, experts recommend thoroughly washing produce for at least one minute. However, washing may not remove all cyclospora spores.

People who are at higher risk due to age or weakened immune systems may want to avoid foods previously linked to outbreaks, including raspberries, basil, salad mixes, cilantro, berry mixes, lettuce and snow peas.

Anyone experiencing diarrhea lasting longer than 48 hours is encouraged to contact a healthcare provider for testing and possible treatment.
