Fast-food chain Taco Bell said on July 16 that it had removed lettuce sold in some of its stores amid a multistate outbreak of cyclosporiasis, a gastrointestinal disease caused by a microscopic parasite.
“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,” Taco Bell said in a statement to news outlets.
Taco Bell said it would replace the lettuce within 24 hours over the possible link to the outbreak. It did not specify the ingredient’s supplier or say which states were affected.
The investigation followed reports from more than 1,644 people infected with cyclosporiasis who said they had eaten at Taco Bell restaurants in Indiana, Kentucky, Michigan, Ohio, and West Virginia.
“FDA [Food and Drug Administration] is working directly with the supplier to determine if contaminated shredded iceberg lettuce went to other places,” the CDC said, without identifying the supplier.
The agency also said that Taco Bell was working to remove the lettuce from its stores and urged people to avoid eating the ingredient.
Of those, 141 were hospitalized, while more than 5,100 additional cases still require further analysis to confirm whether they are domestically acquired cyclosporiasis. No deaths have been reported so far.
Symptoms of cyclosporiasis include loose, watery stool and abdominal pain. Diagnosis typically involves testing stool samples. Antibiotics are usually the preferred treatment.
Health agencies are advising people to wash their hands before and after handling produce, wash produce before preparing, and consider cooking produce before consumption.
