CDC Links Cyclospora Outbreak to Taylor Farms Lettuce Distributed to Taco Bell and Retail Stores

The Centers for Disease Control and Prevention (CDC) has identified Taylor Farms iceberg lettuce sourced from Mexico as a possible origin of a Cyclospora parasite outbreak that has now been reported in 15 states. The investigation was prompted after multiple patients reported eating at Taco Bell, which receives the lettuce for its restaurants in five states. The lettuce was distributed to Taco Bell locations between June 29 and July 16 and to retail stores across 27 states, leading to widespread recalls of shredded iceberg lettuce products.

Cyclospora causes an intestinal illness characterized by severe, prolonged diarrhea, but it is rarely fatal. The CDC noted that two deaths in Michigan involved individuals with significant underlying health conditions that may have been worsened by the infection and dehydration. Because the parasite is difficult to detect on produce, the Food and Drug Administration (FDA) has not yet reported any positive tests from contaminated fruit or vegetables.

In response, Taco Bell temporarily halted service of lettuce, cilantro, onions, pico de gallo and guacamole, while recalls were issued for the affected lettuce in numerous states, including Alabama, Arkansas, Connecticut, Florida, Georgia, and others. Officials warned that rising case numbers do not necessarily indicate ongoing consumption of contaminated produce, as symptoms can appear weeks after exposure and outbreak attribution may take up to six weeks.

"It can take weeks for people to show symptoms of the illness and as long as six weeks to determine if a sick person is part of an outbreak," a CDC spokesperson said.

Public health agencies continue to advise consumers to practice safe food handling and to stay informed about recalled products.
