Investigation Details

June 19, 2020

CDC, public health and regulatory officials in several states, and the U.S. Food and Drug Administration are investigating a multistate outbreak of Cyclospora infections linked to consumption of ALDI Little Salad Bar Brand Garden Salad, Hy-Vee Brand Garden Salad, or Jewel-Osco Signature Farms Garden Salad. The investigation is ongoing to determine whether other products are a source of illnesses in this outbreak.

As of June 19, 2020, a total of 76 people with laboratory-confirmed Cyclospora infections associated with this outbreak have been reported from 6 states:  IA (28), IL (23), KS (1), MN (10), MO (7) and NE (7).

Illnesses started on dates ranging from May 11, 2020 to June 14, 2020. Ill people ranged in age from 16 to 92 years with a median age of 62 and 59% were female. Of 72 people with available information, 16 people (22%) have been hospitalized. No deaths attributed to Cyclospora have been reported.

Illnesses might not yet be reported due to the time it takes between when a person becomes ill and when the illness is reported. This takes an average of 4 to 6 weeks. Please see the Timeline for Reporting Cases of Cyclospora Infection for more details.

There are typically multiple clusters of Cyclospora infections that occur during a given season. It is unknown at this time if other reported cases of Cyclospora infection in the United States this season are linked to contaminated ingredients in these bagged salad mixes. This investigation is ongoing.

Investigation of the Outbreak

Epidemiologic evidence indicates that ALDI Little Salad Bar Brand Garden Salad, Hy-Vee Brand Garden Salad or Jewel-Osco Signature Farms Garden Salad are likely sources of this outbreak, but does not explain all of the cases.

In interviews, ill people answered questions about the foods they ate and other exposures in the two weeks before they became ill. An illness cluster is defined as two or more people who do not live in the same household who report eating at the same restaurant location, attending a common event, or shopping at the same location of a grocery store in the week before becoming ill. Investigating illness clusters provides critical clues about the source of an outbreak. If several unrelated ill people ate or shopped at the same location of a restaurant or store within several days of each other, it suggests that the contaminated food item was served or sold there. In this bagged salad mix-associated cluster, several ill people reported eating ALDI Little Salad Bar Brand Garden Salad, Hy-Vee Brand Garden Salad, or Jewel-Osco Signature Farms Garden Salad. CDC and FDA, together with state health departments, continue to investigate other potential sources of illnesses in this cluster.

This investigation is ongoing, and CDC will provide updates when more information is available.
