‘…[C]ook the produce that you can — heat is the absolute best option for eliminating cyclosporiasis — and to clean your raw fruits, vegetables and herbs as thoroughly as possible.

Wash everything with running water before eating or preparing it. Scrub the firmer fruits, like melons and cucumbers, with a produce brush if you have one. If you see damaged or bruised areas on your fruit or lettuce, cut them away. Even if a food’s package says it’s prewashed, Linder said she advises people to rewash it just to be sure.

Previous outbreaks have specifically been linked to bagged lettuce and salads, so you might consider buying whole heads of lettuce instead. If you do that, cut away the outer layers and then separate the inner leaves to wash them. For green onions, you should cut away the bulby root and the outer layer and then wash them thoroughly. Raspberries were associated with one of the first US outbreaks in the 1990s, and they are particularly tricky to clean given their bumpy surfaces; you may want to consider eating them only after cooking (to prepare a jam or compote, for example) or opt for frozen raspberries for the time being. (Freezing is believed to reduce, if not completely eliminate, the parasite.) And be careful with leftovers: You should refrigerate any unused foods that you plan to eat later within two hours.

You could also consider buying locally sourced foods, Linder said, because cyclosporiasis is more common in food sourced from other parts of the world.

If you do start to experience extreme diarrhea, make sure to hydrate very well to avoid dehydration. Linder told me that if somebody experiences dizziness, they can’t keep fluids down, or they have very dark urine, then they should seek immediate medical attention. And anybody experiencing those symptoms should get in touch with their health care providers and their local health department….’
