Enoki mushrooms tested positive for Listeria monocytogenes in Michigan


The Michigan Department of Agriculture and Rural Development (MDARD) on Saturday night told consumers not to eat the following brand of fresh enoki mushrooms after a sample tested positive for Listeria monocytogenes.

The food safety issue was identified through proactive, routine sampling and testing by the ministry.

The impacted brand is listed below:

  • Xinkang Sheng brand Enoki mushrooms (UPC 6 972304 660027; no batch code) – packed in a clear bag with a green tag and white, red and black Chinese characters. The name “Xinkang Sheng” is written in English on the front of the bag; ‘200’ in white numbers on the back of the bag. (See photos below.)

A sample of these mushrooms was collected in November by MDARD at the Dong Yu China Market d / b / a Way 1 Supermarket located at 2789 Plymouth Road, Ann Arbor, MI. Enoki mushrooms have a long shelf life, so some consumers or restaurants may still have the mushrooms in their kitchens. MDARD is working with its partners in the United States Food and Drug Administration to help the industry remove affected products from commerce and identify other places where products may have been sold.

If consumers, restaurants, or retail stores believe they purchased the product from a location other than Way 1 supermarket in Ann Arbor, please provide information about your place of purchase via MDARD’s online complaints system.

Consumers of Xinkang Sheng brand enoki mushrooms should throw them out. Retailers and restaurants should remove this product from the store and immediately contact their MDARD inspector or the local health department food hygiene department.

Listeria can cause serious and sometimes fatal infections in young children, the frail or elderly, and others with weakened immune systems. Although healthy individuals may only experience short-term symptoms such as high fever, severe headache, stiffness, nausea, abdominal pain, and diarrhea, Listeria infection can cause miscarriages and stillbirths in pregnant women.

No illness has been reported to date in relation to these products. If you think that you or someone in your family has become ill after consuming any of these products, seek medical advice immediately.

Enoki mushrooms should not be eaten raw or undercooked. Mushrooms should be thoroughly cooked and heated to an internal temperature of at least 165 ° F to eliminate the risk of disease due to the presence of harmful microorganisms such as Listeria monocytogenes.
