Public health officials are responding to a record-setting outbreak of cyclosporiasis, with nearly 7,000 cases reported across more than 30 states. The surge has prompted scrutiny of recent federal funding cuts and administrative shifts, as experts warn that strained resources and reduced surveillance capacity are complicating efforts to trace the parasite’s source.
Record-Breaking Case Counts and Regional Impact
The current surge of cyclosporiasis, a parasitic infection known for causing weeks of watery diarrhea, nausea, and bloating, is being described by health officials as the largest in U.S. history. While the parasite is typically associated with summer outbreaks, the scale of the current crisis significantly exceeds previous events, such as the 2019 outbreak that involved 4,700 cases linked to imported basil.
Michigan has emerged as a primary site of the crisis. Natasha Bagdasarian, Michigan’s chief medical executive, noted the severity of the situation in her state, stating, If we ignore the other states and just look at the Michigan numbers, already this is probably the biggest outbreak of cyclosporiasis in US history.
Other states, including Indiana, Kentucky, Ohio, and West Virginia, have also reported cases linked by the Centers for Disease Control and Prevention (CDC). In Missouri, health officials have identified more than 80 cases, though STLPR that the state’s numbers remain lower than those of its neighbors.
Taylor Farms and the Investigation into Produce Suppliers
The search for the source of the parasite has centered on the produce supply chain. Federal officials have pointed to lettuce served at Taco Bell locations across multiple states as a point of contact for many patients. In a statement, the company noted that while the FDA traceback indicated a specific independent farm responsible for less than 1% of the U.S. supply, it chose to remove the entire regional stock.

This development has drawn attention from food safety advocates. Bill Marler, a prominent food safety attorney, expressed frustration regarding the transparency of the federal investigation. They say it’s one processor who processed iceberg lettuce from Mexico, but they don’t name the processor, and that’s pretty unusual,
Marler told St. Louis Public Radio. The producer has previously faced scrutiny, including allegations linked to a 2024 E. coli outbreak in St. Louis, which the company has denied.
Impact of Federal Funding and Surveillance Cuts
Public health experts are increasingly connecting the difficulties in managing this outbreak to a broader decline in public health infrastructure.
The financial strain on state and local departments is significant. The Trump administration’s $12 billion cut to public health funding in March 2025 resulted in layoffs and the closure of regional laboratories, including one in Michigan.
Political Scrutiny and Future Outlook
As the outbreak continues, the focus remains on whether local health departments can maintain sufficient investigation efforts. With federal funds delayed or redirected, and with major suppliers like Taylor Farms withdrawing produce, the challenge for consumers and regulators is to identify the specific farm sources before the parasite spreads further. The situation highlights a growing tension between national public health priorities and the reality of a diminished, underfunded surveillance network.
