Outbreak Investigation of Salmonella Oranienburg: Whole, Fresh Onions (October 2021)

Do not eat, sell, or serve recalled onions from ProSource Produce LLC and Keeler Family Farms

The FDA, along with CDC and state and local partners, is investigating a multistate outbreak of Salmonella Oranienburg infections linked to whole, fresh onions. FDA’s traceback investigation is ongoing but has identified ProSource Produce, LLC (also known as ProSource Inc.) of Hailey, Idaho, and Keeler Family Farms of Deming, New Mexico, as suppliers of potentially contaminated whole, fresh onions imported from the State of Chihuahua, Mexico.

As of November 12, 2021, CDC reports that there are 892 illnesses in 38 states and Puerto Rico. 

FDA’s investigation is ongoing to determine the source of contamination and if additional products or firms are linked to illness. Additional information will be provided as it becomes available.

Recommendation 

Advice for restaurants, retailers and consumers: Do not eat, sell or serve recalled onions, or products containing recalled onions. All recalled onions were supplied by ProSource Produce LLC and Keeler Family Farms and imported from the State of Chihuahua, Mexico between July 1, 2021 and August 31, 2021. FDA has posted a list of additional recalls being conducted by companies that may have received recalled onions from ProSource Produce LLC and Keeler Family Farms. This list includes recalls conducted by companies that further processed the onions by using them as ingredients in new products or by repackaging them. If you cannot tell if your onions were recalled, do not eat, sell, or serve them and throw them out.

Onions may last up to three months if stored in a cool, dry place. Restaurants, retailers, and consumers who suspect having purchased such onions may still have them in storage and should not eat, sell, or serve them, and should throw them out.

FDA recommends that anyone who received or suspects having received recalled onions 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, displays, and storage bins.

Suppliers and Distributors: Do not use, ship, or sell recalled onions. Suppliers and distributors that repackage raw onions should clean, rinse, sanitize, and air dry any surfaces and storage areas that may have come into contact with these products.  Farms and firms within the supply chain of recalled onions, including shippers, distribution centers, retailers and restaurants, should immediately clean and sanitize all food contact surfaces and non-food contact surfaces of equipment and tools that the onions may have touched or that may have become contaminated, including refrigerators, counter tops, storage shelving, trucks or other transportation carriers, etc. If there has been potential cross contamination or mixing of onions from other sources with these products, suppliers and distributors should discard all comingled and potentially cross-contaminated product.

October 20, 2021

The FDA, along with CDC and state and local partners, is investigating a multistate outbreak of Salmonella Oranienburg infections linked to whole, fresh onions. FDA’s traceback investigation is ongoing but has identified ProSource Inc. (also known as ProSource Produce, LLC) of Hailey, Idaho as a source of potentially contaminated whole, fresh onions imported from the State of Chihuahua, Mexico. ProSource Inc. has agreed to voluntarily recall red, yellow, and white onions imported from the State of Chihuahua, Mexico, with import dates from July 1, 2021 through August 27, 2021.

Epidemiological data collected by investigators from the CDC and state and local partners identified 20 illness clusters at restaurants where onions were served. Information from these clusters shows that many ill people ate raw onions. Investigators worked to identify a common food item eaten by all of the sick people in an effort to identify the source of the outbreak.

State officials collected food items from some of the restaurants where sick people ate. The outbreak strain of Salmonella Oranienburg was found in a sample taken from a takeout condiment cup containing cilantro and lime. The sick person reported that the condiment container also contained onions, but none were left in the cup when it was tested. Because multiple food items were present in the container and in the sample that was tested, it is not possible to know which food item was contaminated.

FDA’s traceback investigation identified ProSource Inc. as a common supplier for many of the restaurants that sick people reported eating at, including the restaurant where the sample from the condiment cup containing cilantro, lime, and previously onions, was collected.
