Federal officials have declared that a deadly outbreak of Listeria monocytogenes infections traced to Dole packaged salads has ended.
The most recent patient to be reported became sick on Jan. 15. It can take up to 70 days for symptoms of Listeria infections to appear, but the implicated salad was recalled in October and December 2021 and early January 2022 and had reached its expiration date before January, so officials believe patient counts have stabilized.
The Food and Drug Administration reported on April 4 that the patient count as of that day was 18 people in 13 states. Sixteen people required hospitalization and three people died. States with patients were Iowa, Idaho, Maryland, Michigan, Minnesota, North Carolina, Nevada, Ohio, Oregon, Pennsylvania, Texas, Utah and Wisconsin.
The states where the implicated salad was distributed were Alabama, Arizona, California, Colorado, Connecticut, Florida, Georgia, Hawaii, Iowa, Idaho, Illinois, Indiana, Kansas, Kentucky, Louisiana, Maine, Maryland, Michigan, Minnesota, Missouri, Mississippi, North Carolina, North Dakota, Nebraska, Nevada, New York, Ohio, Oklahoma, Oregon, Pennsylvania, South Carolina, Tennessee, Texas, Virginia, Washington and Wisconsin. The salad may have been further distributed to other states, according to the FDA.
Recalls related to the outbreak began in October 2021 when routine retail sampling by the Georgia Department of Agriculture found Listeria monocytogenes in pre-packaged salad mix from a grocery store, according to the FDA.
