During June-August 2013, CDC, state and local public health officials, and the FDA investigated an unusually large number of reports of cyclosporiasis. A total of 631 persons were reported from 25 states and New York City. Investigators concluded that there were concurrent outbreaks occurring. Iowa and Nebraska health officials concluded that restaurant-associated cases of cyclosporiasis in their states were linked to a salad mix produced by Taylor Farms de Mexico. Most case patients in these two states became ill during June 15-29. Epidemiologic and traceback investigations conducted in Texas indicated that at least some of the illnesses among Texas residents were linked to fresh cilantro. Texas patients reported illness onset in July and August.
