The FDA found the outbreak strains of Listeria monocytogenes in an imported sample of Utopia Foods enoki mushrooms. In December 2022, Missouri state officials, during routine sampling, found Listeria in a sample of Utopia Foods enoki mushrooms. But the bacteria found in the Missouri sample was not the outbreak strain, and that strain was not linked to any reported Listeria monocytogenes illnesses in the United States.
The FDA states that of the three sick in Utopia enoki mushrooms outbreak, there are now two strains of Listeria monocytogenes. Both were found in the sample of Utopia Foods enoki mushrooms. Two patients are sick with one strain, and the third is sick with the second strain.
Utopia Foods recalled their enoki mushrooms on December 13, 2022, and the recall was expanded on January 13, 2023.
