In a startling development, the number of cyclospora infections in Miami-Dade County has nearly tripled within just a week, leaping from six to 17 cases between July 4 and July 11, according to the latest data from the Florida Department of Health as reported by NBC 6 South Florida.
This spike isn't isolated to Miami-Dade. In Broward County, cases rose from five to seven during the same timeframe, while Monroe County, which includes the Florida Keys, reported its first confirmed case. This is particularly concerning due to the area's high tourist traffic.
Statewide, Florida's total number of cases almost doubled in a week, increasing from 50 cases (between May 1 and July 4) to 96 cases (between May 1 and July 11), marking a figure four times greater than the same period last year.
National Outlook on Cyclospora Infections
The national situation mirrors these concerns. The Centers for Disease Control and Prevention (CDC) have confirmed 1,645 domestic cases of cyclospora across 34 states, with over 5,100 additional cases under investigation, bringing the total of confirmed or suspected cases to nearly 7,000. There have been 141 hospitalizations, but fortunately, no deaths have been reported.
The CDC has warned that "the actual number of people affected by this multistate outbreak is likely higher than reported, and the outbreak may not be limited to the states with known cases."
The agency also highlighted that "we anticipate the case count will continue to rise as data is received," partly due to a lag of approximately six weeks between symptom onset and official reporting.
Investigating the Outbreak's Source
The definitive source of the outbreak has yet to be identified. Health authorities in Michigan—the hardest-hit state with over 3,300 cases—have indicated that lettuce or leafy greens often emerge as potential origins during investigations, though no specific producer or supplier has been pinpointed.
Dr. Sohaib Imtiaz, Medical Director at People Inc., mentioned that "health officials suspect the outbreak is linked to contaminated raw produce, with investigators actively tracking potential sources like bagged salad mixes, fresh herbs such as cilantro or basil, raw berries, and green onions."
In response, Taco Bell has voluntarily and temporarily removed fresh ingredients—lettuce, onion with cilantro, pico de gallo, and guacamole—from some locations in southeastern Michigan as a precautionary measure. The company stated it will "closely monitor the situation and adhere to guidance from public health authorities." However, neither the CDC nor the Food and Drug Administration (FDA) has confirmed a direct link to the chain.
Understanding Cyclospora and Its Effects
Cyclospora is caused by the microscopic parasite Cyclospora cayetanensis, which infects the small intestine through the consumption of fresh foods or water contaminated with human feces. It is not transmitted from person to person.
Symptoms—severe watery diarrhea, cramps, nausea, fatigue, and low-grade fever—can persist for weeks without treatment. The parasite is not eliminated by common disinfectants; only cooking can destroy it.
The cyclospora outbreak in Florida has prompted health alerts since early July. The CDC advises thoroughly washing fresh produce under running water before consumption, cooking food thoroughly, and staying informed about market recalls. The agency also stresses that "it is important to wash produce well even if labeled as pre-washed."
With Florida's official cyclospora season extending until August 31, authorities expect case numbers to continue climbing in the coming weeks. The CDC has announced plans to release updates more frequently than in past seasons due to the outbreak's scale.

The outbreak is concerning in Monroe County because it includes the Florida Keys, a region with high tourist traffic, which could potentially increase the spread of the infection.
How is the CDC responding to the cyclospora outbreak?
The CDC is monitoring the situation closely, releasing frequent updates, and working to identify the outbreak's source. They are anticipating an increase in case numbers as more data becomes available.
