Health officials are tracking a growing surge of cyclospora, a parasitic illness, reported in 31 U.S. states, leading to scrutiny of lettuce and other salad greens. Investigators are examining a possible link between fresh ingredients served at certain Taco Bell locations and the outbreak, though the fast-food chain and health authorities emphasize that no specific product or supplier has been confirmed as the source.
Taco Bell has voluntarily removed select fresh ingredients at some restaurants as a precautionary measure while public health officials continue their investigation. In a statement, Taco Bell Corp. said, "The health and safety of our guests is our top priority. Public health officials have not confirmed a link to Taco Bell or any specific ingredient, supplier, restaurant or retailer."
Cyclospora cayetanensis is a microscopic parasite that infects the small intestine after consumption of contaminated food or water, according to the CDC. Since May 1, 1,645 domestic cases have been reported, frequently linked to fresh produce like leafy greens, cilantro, and berries. The CDC is also investigating over 5,100 additional suspected cases, with 145 hospitalizations.
While cyclospora is not generally life-threatening, it can cause severe, prolonged diarrhea that may persist for weeks if not diagnosed and treated, according to Dr. Tammy Lundstrom, senior vice president and chief medical officer of Trinity Health in Michigan. Symptoms can be particularly prolonged in individuals with compromised immune systems.
Amid the ongoing investigation, medical experts advise thorough washing of all fresh produce. Dr. Marc Siegel, Fox News senior medical analyst, recommends washing lettuce and all salad greens thoroughly and practicing good hand hygiene before and after food preparation, noting that the overall risk of contracting the illness remains low.
Registered dietitian nutritionist Caroline Margolis suggests avoiding prewashed, bagged lettuce and salad mixes. Instead, she advises choosing whole heads of lettuce, discarding the outer leaves, and washing them thoroughly. For those who develop cyclosporiasis, she recommends staying hydrated and seeking medical care if necessary, supporting recovery with nutrient-rich and easily digestible foods.
Federal health authorities have not issued warnings to avoid lettuce or other fresh produce. However, Lundstrom reiterated the importance of thoroughly washing all leafy greens, which can significantly reduce the presence of pathogens. For those seeking additional precautions, frozen and canned produce may be considered safer options. The CDC's recommendations for safe food handling include washing hands with soap and water before and after handling produce, washing all fruits and vegetables under running water, scrubbing firm produce, cutting away bruised areas, and refrigerating cut or cooked produce promptly.
"It's important to remember that fruits and vegetables in all forms are an essential part of our daily healthy diet, and by exercising these practical preventive steps, people can still enjoy these nutritious foods," Lundstrom added.
