Federal health officials said Friday that cyclospora cases tied to shredded lettuce had been linked to four additional states, widening a Taco Bell-related outbreak to nine states. The expansion put Michigan and Indiana squarely inside a growing investigation that has now reached 1,947 cases and at least 98 hospitalizations.
For people searching for Cyclospora Cases In Michigan And Indiana, the new count is the immediate reason the outbreak matters today. The illnesses tied to lettuce served at Taco Bell first covered Illinois, Kansas, Oklahoma and Pennsylvania, then grew to include Indiana, Kentucky, Michigan, Ohio and West Virginia, leaving investigators to sort out how far the contaminated product moved before people started getting sick. There have been no deaths reported.
The case total makes this the largest U.S. cyclospora outbreak under review. The Centers for Disease Control and Prevention said it had received reports of more than 4,100 laboratory-confirmed cyclospora cases since May 1, while also investigating more than 7,400 other likely cases across 41 states. Cyclospora is a microscopic parasite that causes intestinal illness and can bring on frequent and sometimes explosive bowel movements.
Federal officials remain focused on lettuce from Taylor Farms as the source of the multistate outbreak. Taylor Farms announced last week that it was recalling iceberg lettuce grown in central Mexico, and investigators are still tracing the supply chain behind the shredded lettuce served at Taco Bell. That matters because the lettuce was part of a broader distribution path, not a single restaurant kitchen event, which is how a contamination problem can spread across multiple states before it is recognized.
There is, however, a point of friction in the investigation. Mexico health officials said Thursday that the parasite was not detected in lettuce or water at the Taylor Farms plant in Guanajuato, even though U.S. officials have not moved away from that source. Mexican health authorities visited the plant between July 18 and 20 and collected 10 samples of iceberg lettuce and 4 water samples, but a negative result there does not end the inquiry; it means the contamination may have come from elsewhere in the chain, may have been missed in sampling, or may have been present only in a batch that was no longer on site.
The next step is straightforward, if not easy: the CDC, FDA and state health officials will keep interviewing sick people about the foods they ate two weeks before they became ill while tracing the lettuce that reached Taco Bell restaurants. The unanswered question is not whether the outbreak expanded on Friday. It did. It is whether investigators can pin the illnesses to one contaminated lot, one handling step or one point in the supply line before more states are added to the list.
On Thursday, the FDA also said it was investigating a separate cyclospora outbreak reported in 72 people, and regulators had not yet identified the products linked to those illnesses.
