A new survey by data company Numerator indicates that approximately 6.5 million U.S. households stopped purchasing pre-bagged salad in July following a multistate outbreak of cyclosporiasis. The data shows that purchases in the category fell by 10.7 percent between June and July as consumers responded to reports of the illness, which is linked to a parasite often found on fresh produce.
The current outbreak has affected 47 states, with at least 27,000 confirmed cases reported by federal officials. Michigan has recorded the highest concentration of the illness, with state health officials reporting 14,277 cases and two deaths. While the Michigan-based outbreak has been linked to produce sold through various retailers and restaurants across the eastern United States, the U.S. Food and Drug Administration (FDA) is continuing to investigate smaller outbreaks of unknown origin, including more than 2,000 cases in Missouri.
In July, the FDA tied an outbreak at Taco Bell locations in Indiana, Kentucky, Michigan, Ohio, and West Virginia to iceberg lettuce processed at a Taylor Farms facility in central Mexico. Taylor Farms subsequently issued a voluntary recall for the lettuce, which remains the only specific product identified by federal investigators in connection with the recent clusters. Health experts note that while washing produce can reduce exposure, the cyclospora parasite is only killed if food is cooked to 158 degrees Fahrenheit.
The scale of the health impact includes at least 27,000 individuals who have contracted cyclosporiasis, a condition that can cause fever, fatigue, and severe dehydration requiring hospitalization. In Michigan alone, 14,277 residents have been sickened, resulting in two fatalities. Because symptoms typically do not appear until two weeks after exposure, the true number of affected individuals may be higher than currently reported figures. The outbreak has also created operational challenges for major food service providers like Taco Bell and suppliers like Taylor Farms, who must manage recalls and supply chain tracing across multiple states.
The situation sets a precedent for how quickly consumer confidence in pre-packaged produce can shift during large-scale foodborne illness events. While iceberg lettuce is the only product currently confirmed by the FDA as a source, the agency is still investigating the origin of other ongoing clusters. Consumers will likely see continued public health warnings and potential further recalls as these investigations proceed. As of late August, the FDA's investigation into the source of smaller outbreaks remains ongoing, and no specific end date for the current alerts has been established.
