Cyclospora Numbers Continue to Rise. CDC identified a cluster in Texas

Posted on August 27, 2013 by


According to a converssation with a representative of the Texas Department of Public Health, the Cyclospora case count is 283 persons.


Investigation Update

Because many of the more recent cases have been reported from Texas, CDC is collaborating with the Texas Department of Health and Human Services and local public health departments to investigate cases of cyclosporiasis reported among people in Texas.

Public health investigators have interviewed ill people in Texas about their exposures during the 2 weeks before they became ill. These interviews have covered what food they ate and where they ate and purchased their food. On the basis of these interviews, investigators have identified a group (cluster) of ill people who reported eating at the same restaurant. A detailed investigation of this cluster is ongoing. This investigation includes listing the different ingredients in the food that was eaten. People who did not get sick but who also ate meals at the same restaurant on the same days as ill people are also being interviewed. The preliminary analysis of results from this ongoing cluster investigation in Texas does not show a connection to salad mix, leafy greens, and salad mix components produced at Taylor Farms de Mexico.

CDC has increased the number of Cyclospora cases today to 601. Texas has now reported that their case count is 274. New York is at 7, and New Jersey at 3.


A total of 269 cases of Cyclospora infection have been reported in Texas in 2013 with the vast majority having onsets in June and July. Most Texas cases are reported from the Dallas/Fort Worth area. DSHS is investigating the cases to identify possible common exposures and to determine whether they are linked to an outbreak in other states, this is according to the Texas Department of Health website. r

If you change the Texas number to 269 in the total from the CDC, that brings the total to 619 cases nationwide.



  • Case Count: 598
  • States: 22
  • Deaths: 0
  • Hospitalizations: 40


A total of 593 cases of Cyclospora infection have been reported from 20 states and New York City, according to the CDC.

The number of cases identified in each area is as follows:

Arkansas (10),

California (1),

Connecticut (2),

Florida (31),

Georgia (5),

Iowa (155),

Illinois (11),

Kansas (4),


Minnesota (2),

Missouri (5),

Nebraska (86),

New Hampshire (1),

New Jersey (2),

New York City (5),

New York (2),

Ohio (2),

South Dakota (1) – NEW

Tennessee (1).

Texas (269),  – NEW

 Virginia (2),

Wisconsin (16) and

Wyoming (1).  – NEW!

Let’s look at statistics.  Texas  has the most Cyclospora cases with 247, followed by Iowa with 155 cases and Nebraska with 86 cases.  Tennessee, New Hampshire, and California  have the least cases of Cyclospora  with one case each. The other states range from 2 cases to  31 cases in Florida.

Only two states, Iowa and Nebraska have named a Mexican subsidiary of Taylor Farms as the source. Only 241 cases out of  593 have a known source or appromimately 40% of the Cyclospora cases have an identifiable source.

Among 423 ill persons with available information, 36 (9%) have reported being hospitalized. 

Thirty states have not reported Cyclospora cases. The Cyclospora cases span from coast to coast. Why is New York City singled out in the count numbers? They should be part of New York’s total, seven.

Nebraska  and Iowa performed investigations within their states and concluded that restaurant-associated cases of Cyclospora infection in their states were linked to a salad mix.

According to the U.S. Food and Drug Administration (FDA), that the salad mix identified by Iowa and Nebraska as being linked to the outbreak of cyclosporiasis in those states was supplied to Olive Garden and Red Lobster restaurants in those states by Taylor Farms de Mexico, S. de R.L. de C.V., a processor of foodservice salads.

No deaths have been reported. That is a good report. It is not yet clear whether the ill persons from all of the states are part of the same outbreak. That is the question on everyone’s mind.
