    Article - En anglais

    Using a direct isolation method Listeria spp. were detected in 101 (47.4%) of 213 houses investigated.

    L. monocytogenes was present in 45 houses (21-1%). Listeria spp. occurred at all sampling sites.

    Dish-cloths (37%) and surface samples round the drain in the bathroom (27.2%) were most frequently contaminated.

    Highest numbers (c. 104 c.f.u./object) were found in dish-cloths and washing-up brushes.

    Lower levels (up to 103 c.f.u./object) were obtained from kitchen sinks, refrigerator vegetable compartment samples and tooth brushes.

    In total, 132 isolations of Listeria spp. were made from 871 samples.

    L. innocua (53%) and L. monocytogenes (41%) were the predominant species in the positive samples.

    Other Listeria spp. were found in only 6% of the positive samples.
