Recommendation
Consumers should not eat and should check their refrigerators and throw away any recalled enoki mushrooms from Sun Hong Foods, Inc. and Guan’s Mushroom Co., because they may be contaminated with Listeria monocytogenes.
Restaurants and retailers should not sell or serve recalled enoki mushrooms distributed by Sun Hong Foods, Inc. and Guan’s Mushrooms Co.
FDA recommends that anyone who received recalled products 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. Listeria can survive in refrigerated temperatures and can easily spread to other foods and surfaces.
At this time, high risk groups, including the elderly, people with weakened immune systems or chronic diseases, pregnant women and their newborn babies, should not eat enoki mushrooms from Korea (Republic of Korea), even if they were not part of the recalls by Sun Hong Foods, Inc. and Guan’s Mushroom Co.
Consumers, restaurants, retailers, and high risk groups should discard and not eat, sell, or serve enoki mushrooms if they cannot tell where they came from.
Enoki mushrooms from Sun Hong Foods were sold in 200 g/7.05 oz clear plastic packaging with a green label; Sun Hong Foods, Inc. is labeled on the back of the packaging underneath the bar code. These products can also be identified by the UPC code: 7 426852 625810. Recalled product was sold to distributors in California, Florida, Illinois, Oregon, and Texas; and was sold to the following retailers: J&L Supermarket, Jusgo Supermarket, ZTao Market, New Sang Supermarket, Galleria Market. This distribution information has been confirmed by the firm, but product could have been distributed further, reaching additional states and retail locations. Laboratory analysis of a sample of these mushrooms found the presence of Listeria monocytogenes, and whole genome sequencing analysis of the sample found that the Listeria monocytogenes found in these mushrooms matched the outbreak strain.
Enoki mushrooms from Guan’s Mushroom Co. were sold in 200 g/7.05 oz clear plastic packaging with the description “Enoki Mushroom” in English, Korean, and French; Guan’s logo is on the front. On the back of the packaging, the UPC code 859267007013 and package code 14-1 are on the lower right corner. Recalled product was sold to distributors and wholesalers in California, New York, and Pennsylvania in white cardboard boxes with Guan’s logo in green color and code “#02473,” but could have been distributed further. Whole genome sequencing analysis is currently being conducted to determine if these products are linked to this outbreak.
Update
FDA, CDC, and state and local partners are currently investigating a multistate outbreak of Listeria monocytogenes infections linked to enoki mushrooms. Enoki mushrooms are a long thin white mushroom, usually sold in clusters. They are especially popular in East Asian cuisine and are also known as enokitake, golden needle, futu, or lily mushrooms.
On March 23, 2020 Guan’s Mushroom Co. recalled all cases of its 200 g/7.05 oz packages of enoki mushrooms imported from Korea (Republic of Korea). The firm recalled product and ceased distribution after the California Department of Public Health found that a sample of these mushrooms was positive for Listeria monocytogenes. At this time, whole genome sequencing analysis is being conducted to determine whether or not enoki mushrooms from Guan’s Mushroom Co. are linked to this outbreak.
On March 18, 2020, the Korean Ministry of Food and Drug Safety (MFDS) issued a press release on their findings related to Listeria monocytogenes and enoki mushrooms. The government of the Republic of Korea investigated four companies that export enoki mushrooms to the United States and detected Listeria monocytogenes in enoki mushrooms produced by two firms in Korea. The Korean MFDS did not name the firms in the press release; the FDA is working to obtain this information. The Korean MFDS did not link product to any illnesses in Korea.
The Korean MFDS has recommended that enoki mushrooms should be cooked before being consumed and starting March 23, 2020, the Korean MFDS will require large production companies of enoki mushrooms to include additional labelling indicating that they should be cooked.
On March 9, 2020, Sun Hong Foods, Inc. recalled all enoki mushrooms imported from Korea (Republic of Korea). The firm recalled product after the Michigan Department of Agriculture and Rural Development found that a sample of these mushrooms was positive for Listeria monocytogenes. Whole genome sequencing analysis of the sample found that the Listeria monocytogenes found in these mushrooms matched the outbreak strain.
The investigation is ongoing to determine the source of contamination and if additional products are linked to illness. Additional information will be provided as it becomes available.
