The Centers for Disease Control and Prevention (CDC) reported over 18,000 confirmed or suspected cases of cyclosporiasis nationwide, with Michigan as the hardest-hit state. The outbreak, linked to contaminated shredded iceberg lettuce from Taylor Farms de Mexico, has led to over 9,500 illnesses in Michigan alone, including 160 hospitalizations. While cases may be peaking in Michigan, experts caution that lab backlogs and reporting delays obscure the full picture.
Recent Developments
The CDC confirmed 4,173 laboratory-confirmed cases across 41 states as of July 24, with Michigan and Ohio among the most affected. Taylor Farms voluntarily recalled iceberg lettuce from Taco Bell restaurants, groceries, and food service suppliers over a week ago. However, the Food and Drug Administration (FDA) has not yet provided updates on its investigation.
Symptoms and Comparison to Salmonella
Cyclospora infections often cause prolonged watery diarrhea, weight loss, cramping, and fatigue, with symptoms lasting weeks or months. In contrast, salmonella typically resolves within a week and includes fever, abdominal cramps, and lethargy. The CDC also tracks a separate salmonella outbreak linked to recalled shell eggs, with 98 cases across 17 states.
Challenges in Tracking
Michigan’s health officials noted that recent case spikes were partly due to reporting delays at one healthcare system. Dr. Natasha Bagdasarian, the state’s chief medical executive, highlighted that lab backlogs and testing supply shortages may undercount mild cases. Emergency department visits for diarrhea have slowed, suggesting a potential decline in new infections.
Ongoing Concerns
While the outbreak appears to be slowing in Michigan, experts emphasize that contaminated produce may still be in circulation. The FDA has not yet identified all sources of the outbreak, and some states, like New York and North Carolina, report unexplained clusters.
