title: [Listeria monocytogenes in pasteurized milk].
abstract: An haemolytic Listeria monocytogenes strain pathogenic to mice was isolated from 6 out of 28 (21.4%) pasteurized milk samples (3.2% fat milk treated at 78 degrees C for 15 s) marketed by a Madrid processing plant. Listeria grayi was recovered from 25 of the samples (89.2%) and L. innocua from 3 samples (10.7%). One milk sample was contaminated with L. welshimeri. No strains of L. ivanovii, L. seeligeri, L. murrayi, or L. denitrificans were isolated. These results show that pathogenic Listeria strains can be isolated from pasteurized milk and reinforce the hypothesis that this food product may be the source of numerous human listeriosis.
