FDA Launches Urgent Probe into Major New Cyclosporiasis Outbreak Sickening Dozens

The FDA is actively investigating a potential new outbreak of cyclosporiasis, a severe stomach illness caused by the Cyclospora parasite, as health officials work diligently to identify the source of infection. This latest cluster involves at least 72 cases, adding to broader 2026 investigations into multiple outbreaks where sources remain unidentified in some instances. The Trump administration's health agencies are moving quickly to protect public health amid these concerning developments.

The CDC has confirmed more than 1,600 domestically acquired cases since May 2026 across dozens of states — a significant increase compared to previous years. One of the largest clusters has been linked to shredded iceberg lettuce served at Taco Bell locations in five states, although some related tests were later identified as false positives. Officials continue traceback efforts across several ongoing outbreaks while emphasizing the importance of food safety practices.

Cyclosporiasis causes severe diarrhea, stomach cramps, and fatigue that can last for weeks, making it particularly debilitating for those affected. Health experts advise thorough washing of all produce and caution when consuming fresh items that are eaten raw. The FDA and CDC remain focused on resolving these outbreaks and providing clear guidance to Americans as investigations progress under the current administration's oversight.
