A California-based produce giant has been at the center of at least five major food safety incidents over the past 13 years, yet regulatory action remains minimal. Taylor Farms, which supplies lettuce, onions, and salad kits to major restaurant chains and grocery retailers, was identified as the supplier behind shredded iceberg lettuce linked to a cyclosporiasis outbreak affecting more than 5,000 people across five states as of mid-July 2026. This marks the second time in a decade that Taylor Farms has been connected to a parasitic outbreak of the same illness.

What Is Cyclosporiasis and Why Should You Care?

Cyclosporiasis is an intestinal infection caused by the Cyclospora cayetanensis parasite, which contaminates produce through feces-contaminated water or poor hygiene practices on farms. The infection causes explosive, watery diarrhea that can last for weeks without antibiotic treatment, along with fever, stomach cramps, nausea, and vomiting. While not typically fatal, the illness can lead to severe dehydration requiring hospitalization. As of July 17, 2026, Michigan alone had reported more than 5,000 cases, with 102 people hospitalized. The Centers for Disease Control and Prevention (CDC) confirmed 1,645 cases nationwide, though the true number is likely much higher because many people recover without seeking medical care.

The outbreak prompted the Food and Drug Administration (FDA) and CDC to warn people in Indiana, Kentucky, Michigan, Ohio, and West Virginia to avoid shredded iceberg lettuce from Taco Bell locations in those states. Taco Bell removed the affected lettuce from its restaurants and stated it would stop using the supplier indefinitely, with plans to source from a replacement supplier within 24 hours.

A Pattern of Recalls and Safety Violations Spanning Over a Decade

The 2026 cyclosporiasis outbreak is not an isolated incident for Taylor Farms. The company's food safety record reveals a troubling pattern of recalls and contamination issues dating back to at least 2013. In 2013, Taylor Farms de Mexico was linked to a cyclosporiasis outbreak that affected 400 people, with 22 requiring hospitalization. The contaminated bagged salad mix was supplied to major restaurant chains including Red Lobster and Olive Garden. Notably, the FDA issued no administrative or regulatory action following that outbreak.

In 2015, Costco recalled its Rotisserie Chicken Salad after a related E. coli outbreak sickened 19 people across seven states. The salad contained a celery and onion diced blend sourced from Taylor Farms. Testing by the Montana Public Health Laboratory detected E. coli O157:H7 in the product, though further FDA testing was inconclusive. Taylor Farms voluntarily recalled the blend as a precaution.

In 2017, the U.S. Department of Agriculture's Food Safety and Inspection Service announced that two Taylor Farms facilities were voluntarily recalling thousands of pounds of chicken and pork salad products due to possible Listeria monocytogenes contamination. Listeria is a pathogen that causes listeriosis, an infection that can be life-threatening for older adults and people with weakened immune systems, and can cause miscarriages and stillbirths in pregnant people.

In 2022, Taylor Farms issued a voluntary recall of Trader Joe's Lemony Arugula Basil Salad Kit because it potentially included undeclared wheat and eggs, both major food allergens. In 2025, the company recalled its Honey Balsamic Salad Kit for potentially containing undeclared sesame and soy, also major allergens.

The most significant incident before the 2026 outbreak occurred in 2024, when slivered onions from Taylor Farms supplied to McDonald's Quarter Pounders caused an E. coli O157:H7 outbreak that sickened 104 people and caused the death of an older adult. An FDA inspection of a Taylor Farms facility in Colorado Springs revealed dirty and wet equipment, inadequate handwashing practices, and Listeria contamination on work surfaces. Despite these serious violations, the inspection resulted in no administrative or regulatory action and no fines.

What Experts Say About Ongoing Risk

"Until an outbreak has been declared to be over, and all information has been obtained and determined, we are currently working under speculations," said Darin Detwiler, author of "Food Safety: Past, Present, and Predictions" and a professor at Northeastern University in Boston.

Detwiler emphasized that microscopic Cyclospora parasites tend to stick to produce with bumpy or uneven surfaces. Several produce items have been linked to cyclosporiasis outbreaks historically:

• Leafy Greens: Basil, bagged salads and salad mixes, cilantro, mesclun lettuce, and parsley
• Berries and Legumes: Raspberries, snow peas, and sweet peas
• Current Risk: Shredded iceberg lettuce from affected Taco Bell locations in five states

"All we know for sure is that there is a known risk associated with the identified Taco Bell lettuce exposure. But there may be other sources that have not been identified yet," said Wade Syers, a doctor of social science and extension specialist for food safety at Michigan State University.

The CDC is investigating other cyclosporiasis outbreaks and illnesses nationally that are unrelated to the Taco Bell lettuce outbreak, indicating that additional contaminated sources may still be circulating.

How to Protect Yourself From Cyclosporiasis and Other Foodborne Illnesses

• Wash All Produce Thoroughly: Rinse vegetables and fruits under running water before eating or preparing them. This applies even to produce labeled "prewashed." Do not use bleach or other cleaning agents, as they are ineffective against the parasite and can leave harmful residues.
• Cook When Possible: Cooking is the most effective way to kill the Cyclospora parasite. Roasting root vegetables or cooking leafy greens eliminates the risk entirely.
• Be Cautious in Outbreak States: If you live in Indiana, Kentucky, Michigan, Ohio, or West Virginia, avoid ordering lettuce at restaurants until public health authorities declare the outbreak over. If you have a compromised immune system, exercise extra caution with all leafy greens.
• Know Your Produce Source: Locally grown produce may carry lower risk because fruits and vegetables grown abroad are more likely to come from countries with less stringent water quality standards. However, all produce should still be washed regardless of origin.
• Practice Hand Hygiene: Wash your hands with soap and water after using the bathroom and before, during, and after food preparation. This prevents contamination from spreading to produce you are handling.

Why Regulatory Accountability Matters

The pattern of incidents linked to Taylor Farms raises critical questions about food safety enforcement. Despite multiple recalls and serious violations documented during FDA inspections, the company has faced minimal regulatory consequences. The 2024 Colorado Springs facility inspection revealed significant sanitation failures, yet resulted in no fines or administrative action. This stands in stark contrast to the potential harm caused by these contamination events.

Public attention typically focuses on restaurant chains like Taco Bell and McDonald's when outbreaks occur, but industry experts argue that produce suppliers themselves should absorb greater scrutiny and accountability. As one source noted, "Perhaps it's time that the leading produce suppliers absorb the scrutiny and be held accountable instead" of the restaurant chains that purchase their products.

The FDA and CDC continue investigating the 2026 cyclosporiasis outbreak and are working directly with Taylor Farms to determine if potentially contaminated lettuce remains on the market. Consumers in affected states should remain vigilant about their produce sources and preparation methods until health authorities declare the outbreak officially over.
