What the evidence describes

The CDC page for the ended November 2022 outbreak describes matching outbreak strains in enoki samples. It advises thorough cooking, separation from foods that will not be cooked, and cleaning hands and surfaces after raw handling. [1]

Adding raw enoki as a last-minute soup garnish may not heat it enough. Refrigeration alone also does not eliminate Listeria. Pregnant people, older adults and people with weakened immunity have particular reason to avoid raw enoki. [1]

What the finding means

The outbreak page is historical evidence, not a current list of every recalled product. Do not eat a recalled product. These handling concerns are separate from the mushroom’s nutrient content or claims made for mushroom supplements. [1]

A hypothetical distinction

Imagine cooked soup is topped with raw enoki immediately before serving. Hot broth does not automatically demonstrate adequate heating of the garnish.
