Symptoms usually begin about one week after eating or drinking something contaminated and may include:

• Frequent watery diarrhea
• Loss of appetite
• Weight loss
• Stomach cramps and bloating
• Nausea
• Fatigue
• Low-grade fever
• Increased gas

Some people don't have symptoms at all but can still be infected.

How do you get this illness?

The parasite spreads when someone consumes food or water contaminated with Cyclospora.

The foods most commonly linked to outbreaks include:

• Bagged salads
• Lettuce
• Fresh cilantro
• Basil
• Raspberries
• Blackberries
• Snow pease
• Fresh veggies and herbs

One important thing to know is that you generally don't catch it directly from another person.  The parasite needs time in the environment before it becomes infectious, making person-to-person spread very unlikely.

Is it common in Illinois?

Illinois has reported cases during past national outbreaks, especially during warmer months when fresh produce consumption is high.  Causes often occur as part of multistate outbreaks traced back to contaminated produce rather than local transmission.

How is it treated?

Doctors usually prescribe an antibiotic.  Without treatment, symptoms can last for several weeks or even longer.  While you can't totally eliminate your risk completely, you can lower it by washing all your fruits and veggies, avoid recalled foods, refrigerating produce properly, and washing your hands before preparing or eating any food.
