The St. Clair County Health Department has confirmed four cases of Cyclosporiasis, an intestinal illness caused by a microscopic parasite. These local cases are part of a larger statewide outbreak that has reached 1,251 cases to date since late June, with the majority in southeast Michigan. While Michigan is currently reporting the highest concentration of cases, health officials are also tracking infections nationwide as several other states report cases.
Dr. Remington Nevin, Medical Director at the St. Clair County Health Department, says the illness causes prolonged diarrhea that can last a week or longer, often alongside cramping, nausea, fatigue, and weight loss. The illness usually goes away on it’s own but down time can be shortened with prescription treatment. Dr. Nevin notes the parasite does not spread person-to-person. Instead, people get sick by consuming contaminated food or water, with current evidence pointing toward fresh produce. State health officials are still investigating the exact source.
To reduce the risk of contracting the illness, Dr. Nevin recommends these practical food safety steps:
- Wash all produce: Thoroughly wash all fresh fruits and vegetables under running water before eating, cutting, or cooking, even if you plan to peel them.
- Handle leafy greens carefully: For lettuce and other leafy greens, consider buying whole heads, discarding the outer layers, and washing the inner leaves well.
- Wash herbs thoroughly: Trim and wash items like cilantro, basil, and green onions.
- Cook when possible: Cooking produce adds an extra layer of safety, as heat kills the parasite.
Dr. Nevin says anyone who develops severe or prolonged symptoms should contact a healthcare provider.
