Enoki Mushrooms Listeria

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.Enoki mushrooms are linked to four deaths and 31 hospitalizations in what the US Centers for Disease Control and Prevention says was a multistate listeria outbreak that is now presumed to be over. A CDC investigation found that the mushrooms were sold by H&C Food Inc., Guan’s Mushroom Co., and Sun Hong Foods, Inc. The mushrooms were supplied to these companies by the Korean company Green Co. Ltd. and were sold between November 23, 2016 and December 13, 2019.

The Green Company is likely the source of the outbreak, the CDC said.In April, the US Food and Drug Administration put the company on an Import Alert and H&C Foods recalled the mushrooms that had been supplied by that company. The Korean Ministry of Food and Drug Safety had also found listeria in enoki mushrooms produced by two firms from that country.

In the US, the 36 illnesses were across 17 states. Two deaths were in California, and there was one death each in Hawaii and in New Jersey. There were also six cases involving pregnant women that resulted in two miscarriages. Listeriosis symptoms usually don’t show up until about a week to four weeks after someone eats contaminated food. Some people have even reported symptoms 70 days after they were exposed to the bacteria. Symptoms include a headache, a stiff neck, loss of balance, confusion, and aches and fever. Pregnant women typically only get a fever and other flu-like symptoms, but a listeriosis infection can lead to a miscarriage.
