ATLANTA (WFXG) - The Center for Disease Control and Prevention (CDC) has issued a notice of two cases of listeria linked to enoki mushrooms.

Two people have been hospitalized in two states, Michigan and Nevada. No deaths have been reported at this time, according to a release by the CDC, which also points out that the disease likely is in other states but has not been tested or reported. The CDC says it takes 3-4 weeks for a person to be reported as part of an outbreak.

Investigators have not identified a specific brand of contaminated enoki mushrooms. There has not yet been a recall issued for this outbreak.

Enoki mushrooms have been recalled more than 20 times since 2020 due to listeria concerns. The mushrooms are white with long, thin stems and often used in Chinese, Japanese, and Korean foods, according to a release from the CDC.

The CDC warns that pregnant people, newborns, adults 65 years or older, and people with weakened immune systems are at higher risk for severe illness from listeria. Symptoms of severe illness usually start within 2 weeks after eating food contaminated listeria. but may start as early as the same day or as late as 10 weeks after.
