Lettuce brands and salad chains are launching consumer education campaigns to reassure shoppers their products remain safe during a cyclospora outbreak that has sickened over 4,100 people across the U.S. since May.
The parasite, which causes intestinal illness, has been linked to iceberg lettuce in nine states. Federal investigators have not yet identified a single source, leaving consumers uncertain about food safety and companies working to distance themselves from the outbreak.
Greenhouse-grown lettuce brands push safety messaging
Gotham Greens, a New York-based producer that grows leafy greens in controlled indoor greenhouses, used social media to clarify its products are unaffected. The company’s website traffic increased more than 800% from July 9 to 19 compared to the previous 10 days, while engagement on its posts rose by double digits.
Jodi Genshaft, Gotham Greens’ vice president of marketing, said the company noticed more questions from consumers and received about 1,300 messages through social media and email. Its greens and herbs are cultivated in hydroponic greenhouses across nine states, avoiding contact with soil, manure, or chemical washing agents. Independent water testing is part of the process.
Genshaft stated that consumers deserve to know how and where their food is grown. She added that transparency helps people make better, safer, and more informed choices.
Across Threads, Facebook and Instagram, Gotham Greens’ posts about the outbreak have garnered more than 9,000 likes. One Threads user commented, “Bought some today and it was so fresh! I am a first time customer, and you immediately became my preferred brand.” On Facebook, another commented, “You just earned yourself another customer. Going out tomorrow to find your greens.”

Little Leaf Farms, another greenhouse-based grower with facilities in Massachusetts and Pennsylvania, posted Instagram videos featuring CEO Paul Sellew explaining why its lettuce does not require washing. In one clip, he said, “I eat it every day unwashed, and it’s perfectly fine,” while standing among rows of greens in a hairnet.
Little Leaf Farms supplies about 8,000 grocery stores nationwide. It uses treated rainwater and human-grade drinking water for irrigation. The lettuce is cut and delivered within 24 to 36 hours. Sellew told journalists that its product differs from field-grown lettuce, where most food safety incidents originate.
Sweetgreen, the fast-casual salad chain, published an open letter from its founders on July 17. The letter stated, “Our food has not been identified in connection with the current cyclospora outbreak.”
Mixed signals from health officials fuel confusion
The outbreak’s origins remain unclear. On July 17, Taylor Farms voluntarily recalled iceberg lettuce after federal investigators connected it to cases in multiple states. Taco Bell, which sourced lettuce from the company, removed the product from its menu. The FDA initially reported a positive test for cyclospora in a sample from Taylor Farms but later called it a false positive.
By July 22, officials announced a new cluster of 72 cases but did not identify a source. The CDC stated that the only reliable way to kill the parasite is by cooking produce to at least 158 degrees Fahrenheit.
Some shoppers are avoiding fresh produce, while others are choosing farmers’ markets for what they believe are safer, more traceable options. The lack of clear answers has created a situation where reputation risks spreading faster than contamination.
Andy Barr, who works in crisis communications, said unaffected brands are acting quickly to separate their supply chains from the narrative. He explained that their goal is not to defend themselves but to eliminate uncertainty before it alters buying behavior.

That urgency appears in the numbers. Foot traffic at salad-focused chains dropped sharply on July 18, with Chopt down 24%, Chipotle down 5.9%, and Cava down 4.7% compared to the January-to-July average. Taco Bell experienced a nearly 30% decline, leading to a $1 lettuce-free promotion to boost sales.
Sellew said his company’s sales have declined, though not as sharply as the broader category. He noted that while the impact is less severe, the situation remains uncertain. “How long will it last? We’ll see.”
The effort to build transparency is about more than immediate sales.
Genshaft said the aim is to restore confidence in fresh produce while attracting new customers. On social media, first-time buyers have already expressed loyalty. “You just earned yourself another customer,” one Facebook user wrote. “Going out tomorrow to find your greens.”
The investigation continues. Until health officials provide clearer answers, brands are relying on education and reassurance to keep consumers engaged.
