Possible Listeria contamination due to enoki mushrooms from China

The U.S. Food and Drug Administration is advising consumers not to eat, restaurants and food retailers not to sell, and to dispose of product labeled as Sun Hong Foods Inc. enoki mushrooms sourced from China due to possible contamination with Listeria monocytogenes.

On November 28, 2022, Missouri state partners, as a part of the FDA-funded Laboratory Flexible Funding Model Cooperative Agreement Program, collected enoki mushroom samples from retail markets in Missouri. One sample labeled as Sun Hong Foods Inc, (Montebello, CA) and sourced from China tested positive for Listeria monocytogenes, but does not appear to match any clinical isolates from active outbreaks.

The FDA is issuing this alert advising consumers to not eat and restaurants and food retailers to not sell Sun Hong Foods Inc. enoki mushrooms sourced from China due to possible Listeria monocytogenes contamination. FDA is also advising consumers, restaurants and food retailers to dispose of Sun Hong Foods Inc. enoki mushrooms sourced from China.

The FDA is awaiting information on further interstate distribution of the enoki mushrooms and will continue to monitor the investigation and provide assistance to state authorities as needed.

Depending on the severity of the illness, symptoms may last from days to several weeks. Mild symptoms may include a fever, muscle aches, nausea, vomiting and diarrhea. If the more severe form of listeriosis develops, symptoms may include headache, stiff neck, confusion, loss of balance and convulsions. For the very young, the elderly, and the immune-compromised listeriosis can result in death.
