Cyclospora Outbreak Hits Iowa: Taylor Farms Recalls Lettuce, Walmart and Taco Bell Pull Products

A widespread Cyclospora outbreak linked to contaminated iceberg lettuce from Mexico has prompted major retailers and restaurant chains to pull products from shelves, with Iowa among the 27 states affected by the recall. Federal investigators are racing to trace the source as cases climb past 1,600.

The Centers for Disease Control and Prevention (CDC) reports more than 1,644 illnesses and 94 hospitalizations across five states: Indiana, Kentucky, Michigan, Ohio, and West Virginia. While no deaths have been reported, the outbreak has triggered a voluntary recall by Taylor Farms, a major supplier to grocery stores, restaurants, and food service providers nationwide.

What Iowa Consumers Need to Know

Iowa is one of the 27 states where Taylor Farms recalled all iceberg lettuce sourced from central Mexico, distributed between June 29 and July 16. The recall includes products sold at retail stores and supplied to restaurants and food service customers. While Iowa is not among the states with confirmed illnesses, the presence of recalled lettuce in the state means consumers should check their refrigerators.

The affected products include shredded iceberg lettuce sold under various brand names at grocery stores and used in restaurants. The FDA advises consumers to throw away any recalled lettuce or return it to the store for a refund.

Walmart Pulls Products in 15 States, Including Iowa's Neighbors

Walmart confirmed it removed four bagged iceberg lettuce salad products from stores as a precaution. The retailer said there have been no confirmed illnesses linked to its products, but it acted after being notified by its supplier. Walmart stores in 15 states were affected, including several neighboring Iowa: Illinois, Indiana, Kansas, Kentucky, Missouri, and Tennessee.

“The health and safety of our customers is a top priority,” a Walmart spokesperson told CNBC. The company is working closely with its supplier and monitoring the situation.

Taco Bell Acts Quickly After Link to Lettuce

Taco Bell was among the first major chains to respond. The FDA confirmed that Taco Bell locations in Indiana, Kentucky, Michigan, Ohio, and West Virginia received recalled lettuce. The chain voluntarily removed the potentially contaminated product from affected restaurants before Taylor Farms announced its broader recall.

“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,” the company said, according to USA Today.

Taylor Farms: Family-Owned Company Expresses Concern

In a statement, Taylor Farms said it is “deeply concerned for those who became ill, their families, and the many Americans whose trust in the safety of their fresh produce has been shaken.” The company noted that the FDA’s traceback investigation pointed to a single independent farm in Mexico, which accounts for less than 1 percent of U.S. iceberg lettuce supply. Nevertheless, Taylor Farms removed all iceberg lettuce from that region indefinitely.

Sysco, the nation’s largest food service distributor, has stopped distributing the affected lettuce and advised customers to discard any products covered by the recall.

Symptoms of Cyclosporiasis: What to Watch For

The outbreak involves Cyclospora cayetanensis, a microscopic parasite that causes cyclosporiasis. Symptoms include:

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

Illness typically begins about a week after exposure but can range from two days to two weeks or more. Without treatment, symptoms can last for weeks. Anyone experiencing persistent watery diarrhea or severe fatigue should contact a healthcare provider and mention possible exposure to Cyclospora, as routine tests do not always screen for the parasite.

What Happens Next?

The CDC and FDA continue to investigate, working with state officials to identify all potentially affected products. As the investigation progresses, additional companies may announce product removals or customer notifications. For now, health authorities say avoiding recalled products and following recall notices remain the best ways to reduce the risk of additional infections.
