Abstract: A method of detecting Listeria monocytogenes. The method comprises providing a culture device with a selective culture medium and a detection article comprising a first indicator system. The selective culture medium facilitates the growth of Listeria microorganisms. When a Listeria microorganism is detected in a sample contacted with the culture medium, the detection article is contacted with the culture medium to detect Listeria monocytogenes.
