Resumo(s)
Several types of food products on sale in Portugal, were examined for the presence of Listeria monocytogenes. Secondary
enrichments, in Fraser broth, were analysed by the mini-Vidas LMO, enzyme-linked fluorescent immunoassay technique. Positive
samples were confirmed by isolation on Oxford and PALCAM selective agars followed by biochemical characterization. Of 1035
samples, 72 (7.0%) were positive for L. monocytogenes, the majority being from raw products (milk, meat, fish, flour) although some
heat-processed or fermented foods (ready-to-eat) were also positive. In Portugal, a predilection for fresh cheese was indicated as a
potential risk for consumers.
