Health officials in the United States have determined that shredded iceberg lettuce sold at Taco Bell restaurants is the origin of an outbreak of cyclosporiasis, a parasitic condition characterized by severe, explosive diarrhea.
Масштаб вспышки и предупреждения
Since early May, over 1,600 confirmed cases of cyclosporiasis have been recorded across the nation, resulting in hospitalizations for 94 individuals. Although no fatalities have been reported, the Centers for Disease Control and Prevention (CDC) cautions that the true number of infections is likely significantly higher due to numerous undiagnosed cases.
On Friday, the CDC named Taco Bell as the source and revealed that a tracing investigation connected the tainted produce to a specific supplier located in central Mexico. Authorities issued a warning advising residents not to consume shredded iceberg lettuce from Taco Bell locations in Indiana, Kentucky, Michigan, Ohio, and West Virginia.
Действия по устранению проблемы
The implicated supplier, Taylor Farms de Mexico, has voluntarily withdrawn all iceberg lettuce from the US market. Investigations are ongoing to ascertain if the contaminated product was supplied to any other restaurants or retail outlets.
Информация о циклоспориозе
Cyclosporiasis is caused by the microscopic parasite Cyclospora cayetanensis. This ailment typically manifests as sudden, watery diarrhea, accompanied by symptoms such as bloating, flatulence, abdominal cramping, nausea, and vomiting. Some affected individuals may also experience fever and fatigue, while others show no signs of illness.
According to the CDC, infection usually occurs through the ingestion of food or water contaminated with fecal matter, with symptoms generally appearing about a week post-exposure. While antibiotics can treat the illness, it is often missed by standard lab tests, complicating diagnosis. If left untreated, the infection can persist for over a month, with recurrent episodes of diarrhea being its most defining trait.
The parasite is naturally found in tropical and subtropical regions. Currently, there is no evidence suggesting that the disease can spread from person to person. Previous instances of cyclosporiasis outbreaks in the US have been linked to imports from Mexico, including cilantro, raspberries, sweet peas, lettuce, and basil.
