Well, my personal fave is the USDA/FSIS method (LC 57). You enrich in UVM 24 h
@ 30 C, transfer into Fraser broth 48 h @ 35 C, and if the Fraser turns blsck,
you've probably got Listeria. Confirm by streaking 48 h Fraser to modified
Oxford plates, 24-48 h @ 35. I have yet to see a rapid ELISA method I trust.
Too many false negatives.
