Summary

A growing outbreak of cyclosporiasis, a parasitic illness, has consumers seeking advice on social media as the source remains unidentified by public health officials. The parasite can cause severe dehydration, particularly in vulnerable populations. Without a confirmed source or official recall, speculation is rampant online, with some users naming specific businesses.
Public health experts recommend avoiding fresh produce that cannot be cooked or peeled until the culprit is found. Previous outbreaks have been linked to items like bagged salad mixes, cilantro, and raspberries. Thorough handwashing and rinsing produce are essential precautions.
Some experts suggest that staffing reductions and changes to disease surveillance systems may have hampered the ability to quickly identify the source of this and similar outbreaks. These surveillance systems were made optional, hindering tracking efforts.
In response to reports, Taco Bell has temporarily removed select ingredients as a precautionary measure, though no link to the outbreak has been confirmed by health officials. Experts emphasize that blame cannot be placed on specific farms or companies without definitive investigation results.
