Latest Update: August 5, 2026
Epidemiologic and traceback data continue to show that iceberg lettuce from Taylor Farms de Mexico (a Taylor Farms central Mexico-based processor) was contaminated with Cyclospora and made people sick.
Epidemiologic data
Since the last update on July 24, 2026, state and local health officials have continued to interview additional cases of cyclosporiasis and CDC has added them to this multistate outbreak. Due to the additional interview data, the outbreak now includes people who reported exposure to Taco Bell or recalled Taylor Farms de Mexico iceberg lettuce. Many of these illnesses began before the Taylor Farms de Mexico iceberg lettuce recall on July 17, 2026. The total case count associated with this multistate outbreak is now 6,358 illnesses reported from 15 states. Since the last update, 6 additional states have been added: Arkansas, Iowa, Missouri, Nebraska, New Hampshire, and North Carolina.
Illnesses linked to this outbreak began on June 22 and onset dates have continued through July 31, 2026. There have been at least 278 hospitalizations reported overall. Two deaths have been reported in Michigan. Of note, the total number of cases reported includes sick people who traveled to one of the 15 states but reside in different states.
The true number of sick people in this multistate outbreak is likely higher than the number reported, and the outbreak may not be limited to the states with known illnesses. This is because some people recover without medical care and are not tested for Cyclospora. In addition, recent illnesses may not yet be reported because it can take as long as 6 weeks to determine if a sick person is part of a Cyclospora outbreak. States in this outbreak may show different illness counts on their websites, as they may also include probable illnesses or update their websites at different frequencies. CDC and FDA are only reporting laboratory confirmed cases.
