Consumers should not eat and should check their refrigerators and throw away any recalled enoki mushrooms from Sun Hong Foods, Inc., Guan’s Mushroom Co., and H&C Food, Inc. 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., Guan’s Mushroom Co., and H&C Food, Inc.

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.

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.

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 April 7, 2020, H&C Foods Inc. recalled 200 g/7.05 oz packages of enoki mushrooms imported from Green Co. LTD of the Republic of Korea. FDA import samples of enoki mushrooms from Green Co. LTD tested positive for Listeria monocytogenes and on April 6, 2020, whole genome sequencing analysis determined that the Listeria monocytogenes found in the positive samples matched the outbreak strain. As a result, On April 7, 2020, Green Co. LTD was placed on Import Alert 99-23, which flags imported shipments from this firm for potential detention without physical examination. The FDA is encouraging the international community to consult the Import Alert.

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.
