At least 514 people have been found ill from Cyclospora infections since June across 17 states, according to the latest update from the U.S. Centers for Disease Control.
Of those ill, 30 have been hospitalized.
New Hampshire is the latest state to include a case.
The case count by state is now as follows:
Arkansas (5 cases), Connecticut (1), Florida (27), Georgia (4), Illinois (9), Iowa (153), Kansas (3), Louisiana (3), Minnesota (1), Missouri (3), Nebraska (79), New Hampshire (1), New Jersey (1), New York (6), Ohio (2), Texas (206) and Wisconsin (10).
While the 232 illnesses in Iowa and Nebraska are known to be from salads served at Olive Garden and Red Lobster restaurants, investigators have not determined a definitive source for the illnesses in other states, including the 206 ill in Texas.
Cyclospora is a single-celled parasite often associated with contaminated fresh produce. Symptoms can take several days or weeks to appear and include watery diarrhea, vomiting, fatigue, nausea and stomach cramps.
