As of September 14, 2015, a total of 546 ill persons with confirmed Cyclospora infection were reported to CDC in 2015.

319 cases have been reported since May 1.

Clusters of illness linked to restaurants or events have been identified in Texas, Wisconsin, and Georgia.

Epidemiologic and traceback investigations conducted in Texas, Wisconsin, and Georgia by state and local public health and regulatory officials and the FDA indicated that some illnesses among residents in these states were linked to fresh cilantro from Puebla, Mexico.

The numbers of reported cases of cyclosporiasis in the United States have returned to baseline levels.

In the United States, foodborne outbreaks of cyclosporiasis since the mid-1990s have been linked to various types of imported fresh produce, including raspberries, basil, snow peas, and mesclun lettuce; no commercially frozen or canned produce has been implicated.
