Taco Bell has indefinitely removed lettuce from its menu after the ingredient was linked to a cyclosporiasis outbreak in the U.S.
The move follows an investigation by health officials into a parasite that causes severe gastrointestinal distress. Because the chain operates thousands of locations, the removal of a core ingredient highlights the scale of the contamination risk and the speed at which foodborne illnesses can spread across state lines.
U.S. health officials, including the Centers for Disease Control and Prevention, identified lettuce as the probable source of the outbreak. Taco Bell said it took the action out of an abundance of caution. The contamination is tied to lettuce supplied from Mexico that was served at locations in five U.S. states [1]. Other investigators are focusing on Taylor Farms lettuce as a possible source of the parasite [2].
Reports regarding the scale of the illness vary. Some data indicates that 145 people have been reported sick across 20 states [3]. However, other reports suggest a significantly higher impact, claiming more than 4,300 people have been sickened in Michigan alone [4].
Cyclosporiasis is caused by the Cyclospora cayetanensis parasite. The infection typically manifests as explosive diarrhea, and stomach pain. Because the parasite is often linked to fresh produce and is difficult to kill with standard washing, health officials often recommend removing the suspected crop from the supply chain entirely to stop new infections.
Taco Bell locations in Michigan and several other states were specifically affected by the contaminated shipments [1], [2]. The company has not provided a date for when lettuce will return to its menu.

This incident underscores the vulnerability of the U.S. fast-food supply chain to international agricultural contamination. The discrepancy in case numbers—ranging from 145 across 20 states to over 4,300 in a single state—suggests either a significant lag in reporting or a localized spike in Michigan that may indicate a more severe point of failure in the distribution network.
