The selective media PALCAM and L‐PALCAMY were evaluated for their potential ability to detect Listeria monocytogenes in faeces. Recovery on PALCAM was almost total, and similar at 30°C and 35°C with or without CO 2 incubation. Warm enrichment in L‐PALCAMY was necessary in order to detect low numbers (<10 2 /ml faeces). Faeces in excess of 0.25 ml/10 ml L‐PALCAMY was inhibitory. The results point to L‐PALCAMY and PALCAM as an epidemiological tool.
