Cyclospora Outbreak Spreads: What Iowans Need To Know
A rapidly growing parasitic infection linked to imported fresh produce is sweeping through Michigan and Ohio, raising serious food safety concerns for Iowans. With over 290 confirmed cases across state lines and a history of similar outbreaks hitting the Midwest, residents should be vigilant about what ends up on their dinner tables.
Outbreak Expands in Neighboring States
The Michigan Department of Health and Human Services is tracking a large and growing outbreak of cyclosporiasis. Between June 22 and July 1, officials identified more than 225 cases across 21 Michigan counties and the city of Detroit. Lynn Sutfin, a spokesperson for the department, warned that the number is expected to climb. Over the border in Ohio, the Toledo-Lucas County Health Department is investigating an additional 65 cases identified between June 25 and July 1.
Despite the regional surge, the U.S. Centers for Disease Control and Prevention (CDC) has not acknowledged a link between the two states. In an emailed statement, CDC Press Officer Lisa George said the agency has no evidence of a single, multistate Cyclospora outbreak linking cases happening right now. The CDC's surveillance website listed only 145 cases nationally as of June 16, a significant lag that leaves Iowans questioning the speed of federal tracking as the illness spreads.
Iowa's History with the Parasite
Iowans are no strangers to this parasite. In 2018, McDonald's restaurants in Illinois and Iowa were identified as the source of a major cyclosporiasis outbreak linked to their salads. The fast food chain was forced to stop selling salads in 14 states after the CDC reported 61 people got sick across seven states. Other past outbreaks have been tied to imported basil and cilantro from Mexico, highlighting a recurring issue with certain imported herbs and greens reaching American kitchens.
Why Imported Produce Poses a Risk
Cyclosporiasis is caused by a microscopic parasite called Cyclospora cayetanensis, which is common in tropical and subtropical regions. When the U.S. relies heavily on imported fresh produce from these areas, American families are exposed to pathogens that domestic agriculture typically keeps at bay. The current outbreak underscores the vulnerabilities in our food supply chain when we depend on foreign sources rather than supporting local American farmers.
State health and agriculture officials in Michigan are actively investigating the source alongside the CDC and the U.S. Food and Drug Administration. Jennifer Bonsky, director of the Human Food Division at the Michigan Department of Agriculture and Rural Development, emphasized the importance of basic food safety while the investigation continues.
We are committed to ensuring food safety across the state and are working in partnership with local health departments to identify the source of the outbreak and keep consumers safe. In these moments, it becomes even more important to follow all of the essential food preparation guidelines.
How Iowans Can Protect Their Families
Cyclosporiasis is not contagious and cannot spread from person to person. The infection comes entirely from consuming contaminated food or beverages. To keep your family safe, health officials recommend strict adherence to food preparation guidelines.
- Wash your hands thoroughly with soap and water before and after preparing food.
- Rinse all fresh produce under running water before eating, cutting, or cooking it.
- Cook produce when possible, as heat can kill the parasite.
- Be cautious with imported basil, cilantro, mesclun lettuce, raspberries, and snow peas, which are common culprits in past outbreaks.
What are the symptoms of cyclosporiasis?
Symptoms typically appear two to 14 days after exposure. They include explosive watery diarrhea, abdominal pain, bloating, nausea, and fatigue. If left untreated with antibiotics, the illness can linger for a month or longer. Anyone experiencing sudden gastrointestinal illness should seek evaluation from a healthcare provider immediately.
Can cyclosporiasis spread from person to person?
No. The parasite requires days to weeks after being passed in a bowel movement to become infectious for another person. You cannot catch cyclosporiasis directly from someone who is currently sick.
Is the CDC tracking this outbreak accurately?
The CDC's surveillance data appears to be lagging behind local reports. As of July 1, the CDC website showed only 145 national cases identified through June 16. However, Michigan reported its first case on June 22, and Ohio's 65 cases were reported after June 25. Local health departments are currently doing the heavy lifting to track the spread, while federal data catches up.
