Updated on February 3, 2022, with final outbreak information.

At least 27 people in Minnesota were part of the multistate imported onion Salmonella outbreak that has ended after sickening at least 1,040 people, according to the final update from the Centers for Disease Control and Prevention (CDC). Many of the people in this outbreak said they ate onions in restaurant food before they developed Salmonella infections. Several recalls were issued for the onions which were imported from Chihuahua, Mexico. (See below.)

The CDC said it first identified this outbreak on September 2, 2021. It grew rapidly over the weeks and months that followed.

The case total from each state is: Alabama (7), Arkansas (19), California (15), Colorado (3), Connecticut (5), Florida (75), Georgia (5), Hawaii (1), Illinois (54), Indiana (2), Iowa (4), Kansas (17), Kentucky (10), Louisiana (8), Maryland (66), Massachusetts (15), Michigan (12), Minnesota (27), Mississippi (3), Missouri (59), Nebraska (10), New Jersey (5), New Mexico (16), New York (23), North Carolina (26), North Dakota (4), Ohio (8), Oklahoma (129), Oregon (2), Pennsylvania (13), Puerto Rico (4) South Carolina (7), South Dakota (9), Tennessee (19), Texas (248), Utah (3), Virginia (71), Washington (1), Washington DC (1), West Virginia (1), and Wisconsin (31).

Symptoms of a Salmonella infection, which include abdominal cramps, nausea, fever, vomiting, and diarrhea that is sometimes bloody, usually develop within six to 72 hours of eating contaminated food. The people sickened in this outbreak, who range in age from less than 1 year old to 101 years old, said their illnesses first began on dates ranging from May 31, 2021, to October 25, 2021, to January 1, 2022. Of 778 patients with information available, 260 were hospitalized.

Focussing on the clusters of illnesses associated with restaurant food, the U.S. Food and Drug Administration (FDA) collected purchasing records from the restaurants where the patients ate and analyzed them to try and identify a common food distributor or supplier. Through this process, the agency was able to identify onions imported from Chihuahua, Mexico, as the source of the outbreak.

Two produce distributors have issued recalls for red, white, and yellow onions, ProSource Inc. of Hailey, Idaho, and Keeler Family Farms in Deming, NM. These onions were distributed to restaurants, foodservice operations, and grocery stores from July 1, 2021, through August 25, 2021. Secondary recalls from HelloFresh, EveryPlate, and Green Giant have also been issued.

In Minnesota, the recalled onions were distributed to restaurants and to Target stores in Plymouth, Stillwater, St. Paul MIdway, and Richfield.
