A California company is recalling fresh mushrooms imported from Korea after state testing returned positive results for Listeria monocytogenes.

The company, Guan’s Mushroom Co. of Commerce, CA, is recalling all cases of its 200-gram/7.05-ounce packages of enoki mushrooms, according to a recall notice posted by the Food and Drug Administration.

Guan’s sent the implicated mushrooms to retailers in California, New York, and Pennsylvania via produce distributors or wholesalers. The company’s recall notice does not indicate if the distributors and wholesalers may have sold the product to other customers. The distribution of the product has been suspended, according to the recall notice.

Consumers can identify the recalled mushrooms by looking for 200-gram/7.05-ounce clear plastic packages with the description “Enoki Mushroom” in English, Korean and French, and Guan’s logo in the front. At the back, there is the UPC number 859267007013 and a package code of 14-1 at the lower right corner. The product is being shipped in a white cardboard box with 25 pieces of 200 grams. The boxes have Guan’s logo in green and #02473 printed on each.

No illnesses have been reported to date in connection with the recalled Guan’s mushrooms. However, earlier this month federal officials reported a 3-year-long listeria outbreak traced to Sun Hong Foods enoki mushrooms.

Consumers who have purchased 200-gram packages of Guan’s enoki are urged to return them to the place of purchase for a full refund. Consumers with a question may contact the company at 323-223-1188.

Established in 1996, Guan’s Mushroom has five distribution centers located in San Francisco, Los Angeles, New York, West Grove, and Toronto, according to the company’s website.

About Listeria infections

Food contaminated with Listeria monocytogenes may not look or smell spoiled but can still cause serious and sometimes life-threatening infections. Anyone who has eaten any of the recalled products and developed symptoms of Listeria infection should seek medical treatment and tell their doctors about the possible Listeria exposure.

Also, anyone who has eaten any of the recalled products should monitor themselves for symptoms during the coming weeks because it can take up to 70 days after exposure to Listeria for symptoms of listeriosis to develop.

Symptoms of Listeria infection can include vomiting, nausea, persistent fever, muscle aches, severe headache, and neck stiffness. Specific laboratory tests are required to diagnose Listeria infections, which can mimic other illnesses.

Pregnant women, the elderly, young children, and people such as cancer patients who have weakened immune systems are particularly at risk of serious illnesses, life-threatening infections, and other complications. Although infected pregnant women may experience only mild, flu-like symptoms, their infections can lead to premature delivery, infection of the newborn or even stillbirth.
