Cyclospora Linked to Lettuce Sickens 122 in 7 States
Cases will likely be in all of these states soon: Arkansas, Illinois, Indiana, Iowa, Kansas, Missouri, Michigan, Minnesota, Missouri, Nebraska, North Dakota, South Dakota and Wisconsin. Salads contaminated with Cyclospora were sold at other stores (Walmart). All salads appear to have been manufactured by one processor (Fresh Express)
122 people with laboratory-confirmed Cyclospora infections and who reported eating bagged salad mix before getting sick have been reported from 7 Midwestern states (Illinois, Iowa, Kansas, Missouri, Minnesota, Nebraska, and Wisconsin). Illnesses started on dates ranging from May 11, 2020 to June 15, 2020. 19 people have been hospitalized. No deaths have been reported.
Epidemiologic evidence indicates that ALDI Little Salad Bar brand Garden Salad, Hy-Vee brand Garden Salad, or Jewel-Osco brand Signature Farms Brand Garden Salad are a likely source of this outbreak.
Bagged salad mixes from ALDI, Hy-Vee, and Jewel-Osco do not explain all of the illnesses in this outbreak.
CDC and FDA continue to investigate to determine whether other products are a source of illnesses in this outbreak.
The CDC and FDA warn do not eat, sell, or serve:
ALDI recalled Little Salad Bar brand Garden Salad sold in Arkansas, Illinois, Indiana, Iowa, Michigan, Minnesota, Missouri, North Dakota, South Dakota and Wisconsin
Hy-Vee recalled Hy-Vee brand 12-ounce bagged Garden Salad sold in Illinois, Iowa, Kansas, Missouri, Minnesota, Nebraska, South Dakota, and Wisconsin.
Jewel-Osco recalled Signature Farms brand 12-ounce bagged Garden Salad sold in Illinois, Indiana, and Iowa.
Cyclospora seems here to stay in the USA
In 2019, multiple outbreaks of cyclosporiasis were identified and found to be linked to different produce items, according to a report from the U.S. Centers for Disease Control and Prevention.
About 10 percent of ill people were associated with a multistate outbreak of Cyclospora infections linked to fresh basil imported from Siga Logistics de RL de CV of Morelos, Mexico.
As of Nov. 13, the most recent data shows 2,408 laboratory confirmed cases of cyclosporiasis were reported to the CDC by 37 states, District of Columbia, and New York City. The patients in that count became ill from May 1 to Aug. 31 and had no history of international travel during the 14-day period before their illness onsets. The median illness onset date was July 1.
In 2019, the domestically acquired cases during the so-called cyclospora season of May 1 through Aug. 31 was higher than the number of cases reported for the same period in 2017 and 2018.
At least 144 people were hospitalized; no deaths were reported.
Multiple clusters of cases associated with different restaurants or events were investigated by state public health authorities, the CDC, and the Food and Drug Administration.
Many cases of cyclosporiasis could not be directly linked to an outbreak, in part because of the lack of validated molecular typing tools for C. cayetanensis, the parasite that causes cyclosporiasis.
"Domestically Acquired" Cyclospora sickens 2,408 in 2019 in 37 states
In 2019, multiple outbreaks of cyclosporiasis were identified and found to be linked to different produce items.
As of November 13, 2019, 2,408 laboratory-confirmed cases of cyclosporiasis were reported to CDC by 37 states, District of Columbia, and New York City in people who became ill during May 1 to August 31, 2019 and who had no history of international travel during the 14-day period before illness onset.The median illness onset date was July 1, 2019 (range: May 1–August 31, 2019).
At least 144 people were hospitalized; no deaths were reported.
Multiple clusters of cases associated with different restaurants or events were investigated by state public health authorities, CDC, and FDA.
Approximately 10% of ill people were associated with a multistate outbreak of Cyclospora infections linked to fresh basil imported from Siga Logistics de RL de CV of Morelos, Mexico.
Many cases of cyclosporiasis could not be directly linked to an outbreak, in part because of the lack of validated molecular typing tools for C. cayetanensis, the parasite that causes cyclosporiasis.
The overall number of domestically acquired cases reported to date for May–August 2019 (i.e., 2,408) is higher than the numbers of cases reported for the same period in 2017 and 2018. This increase may be due, in part, to changes in diagnostic testing practices—namely, increased use of a multiplex molecular test to examine stool specimens. CDC is working with state public health partners to determine whether and to what extent changes in testing practices may have contributed to increased case detection and reporting.
Cyclospora Outbreak linked to Basil sickens 241: Connecticut (1), Florida (62), Georgia (2), Iowa (2), Massachusetts (1), Minnesota (33), New York (131), Ohio (3), Rhode Island (1), South Carolina (1), and Wisconsin (4)
CDC, public health and regulatory officials in 11 states, and the U.S. Food and Drug Administration investigated a multistate outbreak of Cyclospora infections.
As of September 27, 2019, a total of 241 people with laboratory-confirmed Cyclospora infections associated with this outbreak were reported from 11 states: Connecticut (1), Florida (62), Georgia (2), Iowa (2), Massachusetts (1), Minnesota (33), New York (131), Ohio (3), Rhode Island (1), South Carolina (1), and Wisconsin (4). Exposures were reported in 5 states (Florida, Minnesota, New York, Ohio, and Wisconsin).
Illnesses started on dates ranging from June 10, 2019 to July 26, 2019. Ill people ranged in age from 15 to 98 years with a median age of 49 and 70% were female. Six (2%) people were hospitalized. No deaths attributed to Cyclospora were reported in this outbreak.
Epidemiologic evidence and product distribution information indicated that fresh basil exported by Siga Logistics de RL de CV of Morelos, Mexico, was a likely source of this outbreak.
In interviews, ill people answered questions about the foods they ate and other exposures in the 2 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 fresh basil-associated cluster, there were several situations in which people reported eating at the same restaurants.
The FDA and regulatory officials in several states collected records to determine the source of the fresh basil that ill people ate in the five affected states. Product distribution information indicated that the fresh basil that made people sick was exported by Siga Logistics de RL de CV of Morelos, Mexico.
1,696 Cyclospora cases on 2019 in United States
As of August 28, 2019, 1,696 laboratory-confirmed cases of cyclosporiasis were reported to CDC by 33 states, District of Columbia and New York City in people who became ill since May 1, 2019 and who had no history of international travel during the 14-day period before illness onset.
The median illness onset date was June 29, 2019 (range: May 1–August 13, 2019).
At least 92 people were hospitalized; no deaths were reported.
At this time, multiple clusters of cases associated with different restaurants or events are being investigated by state public health authorities, CDC, and FDA.
One multistate outbreak of Cyclospora infections has been linked to fresh basil imported from Siga Logistics de RL de CV of Morelos, Mexico . It is unknown at this time if other reported cases of Cyclospora infection in the United States this season are linked to fresh basil. This investigation is ongoing.
Basil tied to Cyclospora outbreak in 11 States with 205 sick
Two hundred and five people with laboratory-confirmed Cyclospora infections and who reported eating fresh basil have been reported from 11 states; exposures occurred at restaurants in 5 states (Florida, Minnesota, New York, Ohio, and Wisconsin).
Illnesses started on dates ranging from June 10, 2019 to July 18, 2019.
Five people have been hospitalized. No deaths attributed to Cyclospora have been reported in this outbreak.
Epidemiologic evidence and early product distribution information indicate that fresh basil from Siga Logistics de RL de CV of Morelos, Mexico is a likely source of this outbreak.
Cyclospora hits 511 across 15 States
CDC, public health and regulatory officials in multiple states, and the U.S. Food and Drug Administration (FDA) investigated a multistate outbreak of Cyclospora cayetanensis infections.
As of September 11, 2018, CDC was notified of 511 laboratory-confirmed cases of Cyclospora infections in people from 15 states and New York City who reported consuming a variety of salads from McDonald’s restaurants in the Midwest.
Twenty-four (24) people were hospitalized. No deaths were reported.
Epidemiologic and traceback evidence indicated that salads purchased from McDonald’s restaurants were one likely source of this outbreak.
On July 13, 2018, McDonald’s voluntarily stopped selling salads at over 3,000 locations in 14 states. The company has since reportedExternal that it has replaced the supplier of salad mix in those states.
On July 26, 2018, the FDA completed final analysis of an unused package of romaine lettuce and carrot mix distributed to McDonald’s by the Fresh Express processor in Streamwood, IL. The analysis confirmed the presence of Cyclospora in that sample.
