Health and Human Services Secretary Robert F. Kennedy Jr. said at a July 21, 2026 press briefing that a recent outbreak of cyclosporiasis is "under control." He credited source identification and a recall carried out by the companies involved (The Guardian).

Cyclosporiasis is a stomach illness caused by a tiny parasite called Cyclospora. People get sick when they eat food or drink water that has been contaminated with it.

Kennedy's announcement came one day after the FDA reversed a 27-state recall of shredded iceberg lettuce supplied by Taylor Farms. The FDA told the company that a test result showing the parasite had been a "false positive" — meaning the test said the lettuce was contaminated when it actually was not. The false positive came from a quick screening test used on a lettuce sample checked at a border inspection point. It was caught through routine quality-control procedures (AP News; Reuters). The FDA said the false-positive result does not change its ongoing investigation into Taylor Farms (Reuters.

The recall itself moved fast. On July 17, the FDA started a recall of shredded iceberg lettuce served at Taco Bell locations in Indiana, Kentucky, Michigan, Ohio, and West Virginia. That same day, Taylor Farms de México said it was voluntarily removing all iceberg lettuce sourced from central Mexico (FDA). On July 18, the FDA expanded the recall to 27 states, including products sold at stores like Walmart. By July 19, FDA scientists re-checked the products and told Taylor Farms the agency had made a mistake.

The size of the outbreak makes the "under control" message harder to accept. As of July 21, 34 states had reported cases, with the Midwest hit hardest, according to the CDC. The CDC's most recent national data as of mid-July reported more than 1,600 confirmed cases and 5,100 pending cases. Michigan alone reported more than 6,571 cases as of July 21 (The Guardian).

Experts have widely criticized the CDC's response to the outbreak as slow. They say this was the predictable result of deep staffing and budget cuts made by the Trump administration. The administration cut $11.4 billion in pandemic-era grants to state and local health departments. That money had helped build the teams that investigate outbreaks. The administration also fired roughly one-quarter of the CDC's workforce. A federal lab focused on detecting parasitic outbreaks was reduced from 11 staffers to three, and its head resigned. The FoodNet program — a CDC system that tracks foodborne illnesses — was cut from monitoring eight types of germs to just two, making cyclospora tracking optional (The Guardian).

The FDA published an official outbreak investigation page titled "Investigation of 5-State Outbreak of Cyclospora Illnesses" in mid-July, linking the outbreak to iceberg lettuce (FDA). That page was published July 18, the same day the recall was expanded to 27 states.

The broader context here is a food safety system stretched thin. The false positive on the border test forced an abrupt recall reversal across 27 states and major retail chains, then was taken back within 48 hours. That raises questions about how reliable quick screening tests are at import points, especially when fewer specialists are available to double-check results. Cutting the parasitic-disease lab from 11 staff to three means fewer experts are on hand to confirm preliminary findings or do the detailed detective work Kennedy referenced at his briefing.

Michigan's case count alone exceeds 6,571, which is far higher than the CDC's national confirmed-case total of 1,600-plus. That gap likely reflects the difference between state-level reporting, which may include probable and clinical cases, and the CDC's stricter confirmed-case count. The 5,100 pending cases nationally suggest the true number will keep rising as test backlogs clear.

The Cyclospora parasite has always been hard to trace through the food supply. It cannot be grown in a lab for testing, and contamination is often spotty rather than spread evenly across a batch of food. Because cyclospora tracking is now optional under the revised FoodNet program, finding it depends on whether individual states have the resources and willingness to look. The $11.4 billion in grant cuts directly weakened that state capacity.

The FDA's claim that the false positive does not change the ongoing investigation sits awkwardly next to the recall reversal. If the Taylor Farms lettuce was not the source, then investigators need to find what was. That task continues even as Kennedy declares the outbreak controlled. The 34-state footprint and the large number of pending cases suggest the outbreak is still making people sick, not just producing late reports from earlier exposures.
