Cyclospora Outbreak Prompts Iceberg Lettuce Recall Across U.S.

A growing Cyclospora outbreak linked to contaminated iceberg lettuce has led to widespread product removals and recalls across the U.S. Major retailers and restaurant chains have taken action as federal investigators work to identify the contamination source. Walmart has removed several lettuce products, while Taco Bell has pulled potentially affected ingredients as a precaution. Federal officials aim to prevent additional illnesses through these actions, which continue as traceback efforts progress.

Current Impact of the Outbreak

As reported by the Centers for Disease Control and Prevention (CDC), more than 1,644 illnesses and 94 hospitalizations have been linked to the outbreak across five states: Indiana, Kentucky, Michigan, Ohio, and West Virginia. No deaths have been reported, but the investigation remains ongoing.

Details of the Outbreak

The CDC has connected the outbreak to shredded iceberg lettuce. Taylor Farms, a supplier of fresh food products to grocery stores, restaurants, and food services across America, has voluntarily recalled all iceberg lettuce sourced from central Mexico. The outbreak involves Cyclospora cayetanensis, a microscopic parasite causing the intestinal illness cyclosporiasis. Symptoms often include:

• Watery diarrhea
• Explosive bowel movements
• Fatigue
• Loss of appetite
• Nausea
• Bloating
• Weight loss

Illnesses typically begin about a week after exposure but can range from two days to two weeks or more. Without treatment, symptoms can persist for weeks. Investigators traced the illnesses to iceberg lettuce in the food-service and retail supply chain.

On July 17, Taylor Farms announced a recall, published by the U.S. Food and Drug Administration (FDA) on July 18, for all iceberg lettuce products sourced from central Mexico distributed from June 29 to July 16. The recall covers distribution to 27 states:

• Alabama
• Arkansas
• Connecticut
• Florida
• Georgia
• Iowa
• Illinois
• Indiana
• Kansas
• Kentucky
• Louisiana
• Massachusetts
• Maryland
• Michigan
• Missouri
• Mississippi
• North Carolina
• New Hampshire
• New Jersey
• Ohio
• Oklahoma
• Pennsylvania
• South Carolina
• Tennessee
• Texas
• Virginia
• Wisconsin

The company stated an FDA traceback investigation pointed to a specific independent farm as the potential source, despite this accounting for less than 1% of the U.S. iceberg lettuce supply.

Retail and Restaurant Response

The recall includes products sold at retail stores and supplied to restaurants. Sysco, the nation’s largest food-service distributor, has stopped distributing Taylor Farms iceberg lettuce imported from Mexico and advised customers to discard all recalled products.

Walmart’s Actions

Walmart confirmed the removal of several iceberg lettuce products after supplier notification. The FDA noted the recalled lettuce was sold in Walmart stores across 15 states: Alabama, Arkansas, Florida, Georgia, Indiana, Kansas, Kentucky, Louisiana, Missouri, Mississippi, Oklahoma, Tennessee, Texas, Virginia, and West Virginia.

“The health and safety of our customers is a top priority,” a Walmart spokesperson stated.

The company emphasized no confirmed illnesses are associated with the specific products removed, and they continue to monitor the situation closely with their supplier.

Taco Bell’s Precautions

Taco Bell acted promptly after illnesses linked to lettuce served in some restaurants. Affected locations include those in Indiana, Kentucky, Michigan, Ohio, and West Virginia. They stated:

“Based on ongoing conversations with public health officials, and out of an abundance of caution, Taco Bell has taken immediate action to voluntarily remove potentially impacted lettuce from a supplier in select states,” according to USA Today.

Statements from Taylor Farms

In a statement published on July 17, Taylor Farms expressed concern for those who became ill, acknowledging that the FDA identified a potential source of contamination. Despite the small percentage of involvement, they are removing all iceberg lettuce from the affected region.

The recall affects several other retailers, restaurants, and food-service customers supplied through Taylor Farms’ distribution network. Federal officials caution that recalled products could have been packaged in multiple formats and distributed across many states.

Future Actions

The CDC and FDA continue their investigations alongside state officials. The FDA advises consumers to discard any recalled iceberg lettuce or return it for a refund. Anyone experiencing symptoms such as persistent watery diarrhea should consult a healthcare provider, citing potential Cyclospora exposure.

Health authorities recommend avoiding recalled products and following recall notices to mitigate additional infections while investigations continue. For more information, contact Newsweek editors Tobias Meyjes and Tony Phillips.
