The adherence of Pseudomonas fluorescens cells to nine food-processing contact surfaces was evaluated using the plate-count method. The surfaces include marble, granite, stainless steel, polyvinyl chloride, polyurethane, and silicone-coated cloth, which have been used only in a few studies concerning bacterial adherence. The number of cells adhered to the surfaces increased with contact time reaching 5.0-6.1 log CDM.cm-2 after 10 hours, which can be considered a well established adherence process. The number of adhered cells doubled in 29.5 minutes and 23.5 minutes on stainless steel and thin polyvinyl chloride-coated cloth, respectively. For the other surfaces, this value was 9.8 minutes on average. Marble, granite, thick polyvinyl-coated cloth, double-faced rugous polyurethane, and silicone-coated cloth were not different (p < 0.05) in their ability to adhere cells (CFU/cm²) after 2 and 10 hours. The surfaces that had higher percentage of similarity in the adhesion level and higher log CFU/cm² of adhered cells were double-faced rugous polyurethane, silicone-coated cloth, and granite. The surfaces showed very different microtopography characteristics when viewed using scanning electron microscopy. This experiment showed the importance of using appropriate materials for food contact during processing, which will affect the cleaning and sanitation procedures. A adesão de Pseudomonas fluorescens foi avaliada em nove tipos de superfícies de processamento de alimentos por contagem padrão em placas. Superfícies de mármore, granito, aço inoxidável, poli(cloreto de vinila), poliuretano e silicone revestidos com tecido foram avaliadas. O número de células aderidas aumentou com o tempo de contato, alcançando 5,0-6,1 log UFC.cm-2 após 10 horas, o qual pode ser considerado um processo de adesão bem estabelecido. O número de células aderidas duplicou em 29,5 minutos em aço inoxidável e 23,5 minutos em poli(cloreto de vinila) revestido com tecido. Nas outras superfícies, em média, esse valor foi 9,8 minutos p > 0,05) no grau de adesão de células após 2 e 10 horas. As superfícies avaliadas com elevadas porcentagens de similaridade no nível de adesão e contagens de células aderidas foram poliuretano rugoso dupla face, silicone revestido com tecido e granito. As superfícies apresentaram características de microtopografias diferentes quando observadas por microscopia eletrônica de varredura. O experimento mostrou a importância da escolha adequada de materiais para contato com alimentos durante o processamento, os quais irão afetar os procedimentos de limpeza e sanitização
