One of America’s most popular fast-food chains is under scrutiny as federal and state health officials investigate whether Taco Bell locations may be connected to a rapidly growing cyclosporiasis outbreak.
Federal and state health agencies are investigating whether Taco Bell locations may have contributed to a widespread outbreak of cyclosporiasis, a gastrointestinal illness caused by a microscopic parasite, according to two anonymous sources familiar with the investigation who spoke to The Washington Post.
In recent days, multiple local and national news outlets reported that signs appeared at Detroit-area Taco Bell restaurants notifying customers that the locations could not serve lettuce, cilantro onions, pico de gallo or guacamole because of "a national recall."
