Health and Human Services Secretary Robert F. Kennedy Jr. says the ongoing US outbreak of cyclosporiasis is “under control,” and that the likely source of the infections has been identified. The comments come after the FDA reverses course on a recall that had been issued for shredded iceberg lettuce distributed across 27 states, with the agency later saying the reported product was a “false positive.”

Multiple outlets report that experts have cautioned that infections may continue to rise even if the suspected exposure has been stopped, citing the time it can take for symptoms to develop and for cases to be detected. ABC News reports the outbreak involves at least 1,600 cases across five states, while other coverage describes thousands of suspected or confirmed illnesses nationwide.

Fox News notes that, as of the reporting, the FDA has not confirmed a positive lab result. The overall reporting reflects disagreement about how conclusively the source has been established, even as Kennedy argues the outbreak is being contained.
