Health and Human Services Secretary Robert F. Kennedy Jr. declared the cyclospora outbreak “under control” on July 21, 2026, as federal agencies identified shredded iceberg lettuce from Taylor Farms’ central Mexico facilities as the source, though conflicting statements and unresolved questions remain.
Health and Human Services Secretary Robert F. Kennedy Jr. asserted during a press briefing on July 21, 2026, that the multistate cyclosporiasis outbreak is “under control,” citing the identification of the source and a voluntary recall by Taylor Farms. The Food and Drug Administration (FDA) has linked the outbreak to contaminated shredded iceberg lettuce from the company’s central Mexico facilities, though its investigation faced confusion after an initial false positive test result for the parasite.
RFK Jr.’s Assurance and Agency Responses
Kennedy, speaking at a healthcare fraud briefing, stated, We have done extensive forensics, epidemiological forensics, and we have identified the source of the outbreak. We, and the companies that are involved, have implemented a recall.
This echoed statements from the Centers for Disease Control and Prevention (CDC), which reported 1,645 confirmed cases and 141 hospitalizations as of July 21, with no deaths. However, the secretary faced questions about federal agency cuts, including reductions in the FoodNet program, which tracks foodborne illnesses. We did cuts in the FoodNet program, but they were for redundant surveillance,
Kennedy said, defending the agency’s actions.
The FDA’s investigation faced scrutiny after initially reporting a positive test for cyclospora in a sample of Taylor Farms’ lettuce, which it later retracted as a false positive.
Despite this, the agency maintained its focus on the company’s products, stating, FDA's traceback investigation and outbreak data continue to converge on shredded iceberg lettuce from Taylor Farms locations in central Mexico.
The agency emphasized its ongoing efforts to ensure contaminated products are removed from the market.
FDA’s Investigation and False Positive Controversy
The FDA’s initial false positive test sparked public confusion, leading to a clarification that the result was an error. However, the agency reiterated its stance that Taylor Farms’ lettuce remains the primary suspect. We do have the outbreak under control,
Kennedy reiterated, though the Michigan Department of Health and Human Services noted 6,571 cases in the state as of Tuesday, with officials cautioning that no specific type of produce, grower, or supplier has been identified as the source.
Conflicting narratives emerged between U.S. and Mexican officials. While the FDA and CDC pointed to Taylor Farms, Mexico’s health secretary, David Kershenobich, stated his country’s investigation had found no evidence that the outbreak originated there.
This discrepancy highlights the challenges of tracing a parasite with a lengthy incubation period and delayed symptom onset, complicating efforts to pinpoint the exact source.
State-Level Data and Ongoing Concerns
The CDC reported that illnesses first appeared on May 13, with over 5,100 additional cases under investigation. State health departments, including Michigan’s, continue to report cases, though the agency acknowledged reporting delays. In all the states,
Kennedy said, we’re still doing forensics,
a claim echoed by officials in multiple states. However, food safety experts warn that scaled-back surveillance programs, like the FoodNet reductions, may hinder future outbreak tracking.
Experts like Keith Schneider of the University of Florida noted the FDA’s broader investigation, which includes testing irrigation water and soil samples. They may be testing irrigation water. They may be testing soil samples,
he said, suggesting the probe extends beyond lettuce. Meanwhile, Barbara Kowalcyk of George Washington University expressed concern that without active surveillance, many cases will be missed,
complicating efforts to understand the outbreak’s full scope.
Unresolved Questions and Public Health Implications
Key uncertainties persist, including the exact origin of the outbreak and the long-term impact of reduced surveillance programs. While Kennedy and the FDA maintain control, the Michigan Department’s acknowledgment that other food items cannot be ruled out
underscores the complexity of the investigation. The FoodNet program’s cuts, which removed mandatory reporting for cyclospora, have drawn criticism from researchers who argue that active surveillance is critical for preventing future outbreaks.
As the investigation continues, public health officials urge consumers to remain vigilant. We will continue to work with federal and state partners to investigate this multistate outbreak and ensure products implicated in this outbreak have been removed from the market,
the FDA stated. For now, the balance between confidence in containment and lingering doubts about the outbreak’s origins remains a central challenge for officials and the public alike.
