How Western Slope Residents Can Safely Wash Produce Amid Cyclospora Outbreak

1,500 cases. That is the number of people diagnosed with cyclospora in Michigan alone, according to the Associated Press. The parasite is currently driving a summer outbreak that has sickened thousands across 30 states, turning routine farmer’s market trips into a potential health hazard.

The culprit is Cyclospora cayetanensis, a microscopic parasite that infects the small intestine. It spreads through food or water contaminated with feces. The symptoms are not subtle: watery diarrhea, cramping, bloating, and fatigue that can linger for weeks. For locals who enjoy fresh berries, basil, or bagged salads, the risk is real, but it is not reason to abandon the produce drawer.

Dr. Erika Noel, a pediatrician and assistant professor at Hawaii’s medical school, told the AP that we do not need to panic. The health benefits of fresh fruits and vegetables outweigh the risks, provided you follow specific cleaning protocols. The key is understanding that soap works where sanitizer fails. Alcohol-based hand sanitizers do not kill cyclospora. Soap and water do.

The CDC notes that symptoms typically begin two to 10 days after exposure. Untreated, they can last from a few days to more than a month, often disappearing and then returning. Anyone with these symptoms should contact a health care provider. But for the rest of us, the solution is largely mechanical and logistical.

Start with hand washing. Dr. Noel recommends using soap and water for at least 20 seconds after using the bathroom and before handling food. This is basic hygiene, but it matters because the parasite enters through ingestion.

Next, look at your prep station. Wash cutting boards and countertops with soap and hot water. Use separate boards for fresh produce versus raw meat, poultry, or seafood. This prevents cross-contamination, a common vector for infection.

The most critical step is washing the produce itself before you peel or cut it. A knife or peeler can carry contamination from the dirty outer skin to the edible interior. This applies even if you do not eat the rind.

Specific items require specific attention:

• Herbs: Separate the leaves on cilantro and basil to ensure water reaches all surfaces.
• Green onions: Cut off the roots, remove the outer layer, and rub the surface under running water.
• Lettuce: Skip pre-mixed bags. Buy a head of lettuce and remove the outer leaves, which are most likely to harbor contaminants.
• Melons: Scrub the outside before chopping.

Previous outbreaks have been linked to raspberries, basil, cilantro, snow peas, and salad mixes. The current source remains unidentified, but the pattern is clear.

For Western Slope residents, this means a slight shift in routine rather than a change in diet. You do not need to stop buying local berries or herbs. You just need to spend an extra minute on them. The cost of a bad bag of salad is a few days off work or school. The cost of proper washing is negligible.

The data from Michigan suggests that while the outbreak is large, it is manageable. The infrastructure of our local markets remains sound. The risk is concentrated in specific items, not the entire supply chain. Keep your hands clean. Wash your melons. Separate your boards. The summer will remain summery, and your stomach will likely agree.
