Results of Listeria analysis in cheese, poultry and other samples from dairy and poultry processing plant (973 samples) using the overlay technique described by BLANCO et al. (1989) to detect and count haemolytic Listeria colonies are reported. The overlay technique was found to be specially useful to count and detect haemolytic Listeria (in most of cases L. monocytogenes) in situ, on the isolation selective agar, in samples with more than one species of Listeria (64 % poultry samples).
