Outbreak Expands to 15 States
On August 5, U.S. health authorities announced that the cyclosporiasis outbreak linked to iceberg lettuce from central Mexico now involves 15 states. The newly added states are Missouri, Arkansas, Iowa, Nebraska, New Hampshire and North Carolina. The total number of reported illnesses has risen to 6,358, with at least 278 hospitalizations according to the Centers for Disease Control and Prevention (CDC) and the Food and Drug Administration (FDA).
Source Tracing and Earlier Findings
The outbreak was first identified in five states through lettuce served at Yum Brands’ Taco Bell restaurants. Subsequent investigations traced the contaminated lettuce to Taylor Farms in central Mexico. Later, the agencies broadened the outbreak to nine states, and surveillance continues to seek additional sources beyond iceberg lettuce.
Business Impact and Consumer Behavior
Quick-service chain Salad and Go filed for bankruptcy on Tuesday and announced the closure of more than 70 of its remaining locations, citing the cyclospora outbreak alongside rising gas prices and reduced consumer spending. The company has been closing locations since September 2025, after operating at its peak with 146 sites across Arizona, Nevada, Texas and Oklahoma.
Foot traffic at Taco Bell has declined daily since July 13, with a brief uptick on July 28 during a promotional event. Data from Placer.ai show visits were down 11.1 % on August 1 compared with the average for Saturdays between January 1 and early July, following a 19.1 % decline the week prior. A report cited by Salad and Go indicates that competitors experienced foot-traffic reductions of 3.15 % to 11.5 %, a range described as “devastating” for the tight-margin fast-casual dining industry.
Case Numbers and Hospitalizations
Michigan health officials reported 12,218 cases as of the latest update, an increase of 710 from the previous day, and 193 hospitalizations as of July 30. The state also recorded its first two deaths linked to the outbreak, both individuals having significant underlying health conditions. Arkansas reported 205 cases, while North Carolina added 149 new cases since July 28, with nine new hospitalizations. The North Carolina health department noted that exposures to Taco Bell or lettuce represent a small proportion of the overall case increase and that a recent decline in new cases suggests primary sources have moved through the food chain.
Official Responses
The CDC continues to investigate multiple clusters across 47 states, emphasizing that the multistate outbreak remains linked to iceberg lettuce. State health departments in Arkansas and North Carolina confirmed their inclusion in the expanded outbreak and provided the latest case counts. Both agencies stress ongoing surveillance and public advisories to reduce consumption of raw produce that may be contaminated.
