Salmonella Infected Onions

ALEXANDRIA, Va.—The Food and Drug Administration, Centers for Disease Control and other local partners have narrowed down the source of the Salmonella Oranienburg outbreak which the CDC began investigating in September.

The multistate outbreak of Salmonella Oranienburg infections is linked to whole, fresh onions sold in foodservice and restaurants. Authorities have narrowed the source of the contaminated onion to ProSource Inc. of Hailey, Idaho, imported from the State of Chihuahua, Mexico.

ProSource is voluntarily recalling red, yellow and white onions imported from the State of Chihuahua, Mexico, with import dates from July 1, 2021, through Aug. 27, 2021. These onion types can be described as jumbo, colossal, medium, sweet onions, among other descriptors.

As of Oct. 18, 2021, 652 people infected with the outbreak strain of Salmonella Oranienburg have been reported from 37 states, with illnesses starting from May 31 to Sept. 30.

The FDA advises restaurants, retailers and consumers not to eat, sell or serve red, yellow and white onions supplied by ProSource that were imported from Chihuahua, Mexico, during the designated time period, or products containing the onions. Because onions can last up to three months in cool, dry storage, the FDA advises that anyone who suspects they purchased the contaminated onion to throw them away.

FDA recommends that anyone who received or suspects having received contaminated onions to use extra vigilance in cleaning and sanitizing any surfaces and containers that may have come in contact with these products to reduce the risk of cross-contamination. This includes cleaning and sanitizing cutting boards, slicers, countertops, refrigerators and storage bins.
