Federal and state health officials are reportedly investigating whether Taco Bell may be connected to a multistate parasite outbreak that has sickened thousands of people across the United States.

 

The investigation follows a nationwide outbreak of cyclosporiasis, an intestinal illness caused by the microscopic parasite Cyclospora cayetanensis. According to the Centers for Disease Control and Prevention (CDC), the parasite typically contaminates fresh produce and can lead to watery diarrhea with frequent, and sometimes explosive, bowel movements.

Authorities believe lettuce is the most likely source of the outbreak, but they have not identified a specific grower or supplier responsible.

What is Cyclospora cayetanensis?

The CDC says people infected with cyclosporiasis may also experience symptoms including loss of appetite, bloating, fatigue, low-grade fever, stomach cramps, nausea, and vomiting.

 

As health officials work to determine the source of the outbreak, Taco Bell has voluntarily removed several fresh ingredients from select restaurants. Customers at some locations have reported seeing signs that read: “We are currently unable to sell Lettuce, Cilantro Onion, Pico de Gallo and Guacamole due to a nationwide recall,” according to UNILAD.
