A CBS News-YouGov poll released on July 27, 2026, indicates that 40% of U.S. adults are buying or eating less produce due to a nationwide outbreak of cyclosporiasis, while only 4% reported increased purchases. The majority, 56%, stated their eating and shopping habits have not changed.
The Centers for Disease Control and Prevention (CDC) recently added four states—Illinois, Kansas, Oklahoma, and Pennsylvania—to the investigation of the outbreak, which now includes nine states: Indiana, Kentucky, Michigan, Ohio, and West Virginia.
Initially, federal investigators linked the outbreak to shredded iceberg lettuce served at Taco Bell, traced to a supplier in Mexico. However, the Food and Drug Administration later determined a positive test result was a false positive.
As of now, at least 1,947 individuals have been reported sick due to the outbreak, with 98 hospitalized. The affected lettuce was distributed across at least 27 states, prompting health officials to advise consumers to avoid the products and to discard or return them.
Since May 1, the CDC has confirmed 4,173 domestically acquired cases across 41 states and is reviewing over 7,400 additional reports to ascertain their connection to existing outbreaks. Investigators are also looking into illnesses reported outside the nine-state outbreak to determine if they are linked to other contaminated products. In North Carolina, recent cases have not been tied to the recalled lettuce but may involve parsley and cilantro, although the investigation is ongoing.
