Kentucky is one of at least 17 states experiencing an increase in cases of cyclosporiasis, an intestinal illness. In collaboration with local health departments and other partners, the Kentucky Department for Public Health is investigating possible sources of this illness to keep Kentuckians healthy.
Cyclosporiasis is treatable, and many people recover without needing medical treatment. It is spread through food and water contaminated with Cyclospora parasites, and usually does not spread from one person to another. If you have symptoms of cyclosporiasis, such as watery diarrhea, and you are concerned about your health, please contact your doctor or other health care provider.
While no source has currently been identified for the current cases of cyclosporiasis, previous outbreaks of cyclosporiasis have been linked to fresh fruits and vegetables, such as lettuce, herbs, and berries.
To reduce risk of cyclosporiasis:
• When appropriate, cook produce to at least 158°F.
· Wash all produce thoroughly under running water.
· Buy whole heads of lettuce and leafy greens rather than pre-washed, bagged lettuce or salad mixes.
· Throw away the outer two or three layers of leaves and wash the inner leaves under running water.
· Always wash your hands before preparing food and before eating.
