Iowa law prevents officials from releasing names in cyclospora case

Posted: Updated:

Iowa law is preventing state health officials from releasing the name or names of salad brand mixtures implicated in a widespread cyclospora case that has sickened dozens across Iowa.

The law states officials can only release the identity of businesses if the problem persists, which officials don't believe is happening because of a drop in cases, officials said in a release on Wednesday.

The Iowa Department of Health on Wednesday said Iowa Code Section 139A.3(2)c "requires IDPH to prevent the identification of any business involved in a disease outbreak, and authorizes release of the identity of a business to the public only when the state epidemiologist or director of public health determines such a release of information is necessary for the protection of the public."

A total of 145 cases have been reported as of Wednesday in the cyclospora outbreak. Officials said there has been a decline in new cases, though Iowa had the highest number of cases in the multi-state outbreak.

Around 80 percent of the cyclospora outbreak has been traced back to a pre-packaged salad mixture.

Officials said a recall of the unnamed product is not necessary because they do not believe the cyclospora is still in the food supply.

The department also said. the business or businesses "could not have taken any action to prevent contamination of the mixture since it came pre-packaged and ready to eat."

The full press release from Wednesday is below:

-------------------

The Iowa Department of Public Health (IDPH), in cooperation with the Iowa Department of Inspections and Appeals (DIA), local public health officials and the CDC and FDA, has been investigating what has become a national Cyclospora outbreak for several weeks. Iowa continues to have the most cases reported in the multi-state outbreak, with 145 cases reported as of today. The number of new cases being reported continues to decline.

Interviews with ill individuals and food trace back investigations have led to the identification of a pre-packaged salad mixture as the source of Iowa’s outbreak. More than 80 percent of Iowa’s cases reported eating the same pre-packaged salad mix that contained iceberg and romaine lettuce, red cabbage, and carrots. The mixture came into Iowa already packaged and already contaminated. “The process that led to the implication of the pre-packaged salad mixture as the outbreak source is a good illustration of how public health investigations work,” said IDPH Medical Director, Dr. Patricia Quinlisk.

As cases began to be reported to IDPH in early July, epidemiologists interviewed those who were ill to determine what and where they had eaten. As an example of the complexity of this investigation, over a 100 different restaurants were patronized by cases during the time that they could have been exposed to Cyclospora.

Since Cyclospora has historically been associated with contaminated fresh fruits and vegetables, these exposures were looked at very closely. It was quickly determined there were no fruit or fruit products in common and IDPH informed the public a vegetable was likely the source. As the public health investigation progressed, detailed interviews were performed where clusters of cases occurred. These cluster investigations further implicated a specific type of prepackaged salad mixture (that included iceberg lettuce, romaine lettuce, red cabbage, and carrots). The DIA investigation continued in parallel and began to point to a specific prepackaged salad mix. Further investigation determined the salad mixture came from the same origin, even though exposures occurred at various locations. DIA was instrumental in determining that 80 percent of Iowa cases had been exposed to the specific pre-packaged salad mix. Once it was determined this was an interstate, and possibly international food product, FDA became involved.

IDPH has not released the name of the salad mixture brand, or locations where it was purchased or eaten because of confidentiality mandated by Iowa state law. Iowa Code Section 139A.3(2)’c’ requires IDPH to prevent the identification of any business involved in a disease outbreak, and authorizes release of the identity of a business to the public only ‘when the state epidemiologist or director of public health determines such a release of information is necessary for the protection of the public.’ Because the vast majority of illnesses occurred in mid-June and the limited shelf life of fresh produce, IDPH and DIA determined the implicated salad mix was no longer in the Iowa food supply chain. Thus, there is no ongoing threat to the public health which would require the identification of a particular brand, store, or restaurant where the salad mixture was available. In addition, these sites could not have taken any action to prevent contamination of the mixture since it came pre-packaged and ready-to-eat.

If it had been determined the source of the outbreak was still in the food supply chain, or that a business was refusing to take some action necessary to protect the public’s health, IDPH would inform Iowans about the exact product or source in order to protect their health. In such a case, a recall of the item would be facilitated by the FDA. Neither action was necessary in this outbreak.
