This study was performed to investigate the efficacy of chemical sanitizers (viz., chlorine, chlorine dioxide, alcohol, and quaternary ammonium compound) against on five food contact materials under different conditions (smooth vs. scratched and with vs. without biofilms). After incubating materials in suspension, cell adhesion on a smooth surface (10 cm) was in the following ascending order: stainless steel (7.36 ± 0.08 log CFU), glass (7.51 ± 0.26 log CFU), polyethylene (7.66 ± 0.30 log CFU), polypropylene (7.76 ± 0.30 log CFU), and wood (8.02 ± 0.33 log CFU). The efficacy of sanitizers was dramatically reduced in the presence of a biofilm on all materials. Among four different chemical sanitizers, chlorine showed the best bactericidal activity against on the surface with scratch and biofilm. Selection of adequate materials, maintenance of a smooth surface, and inhibition of biofilm formation are good practices for food safety.
本研究旨在调查化学消毒剂（即氯、二氧化氯、酒精和季铵化合物）在不同条件下（光滑表面与划痕表面、有生物膜与无生物膜）对五种食品接触材料上的[细菌名称未给出]的消毒效果。将材料在[细菌名称未给出]悬浮液中培养后，在光滑表面（10厘米）上的细胞黏附情况按升序排列如下：不锈钢（7.36±0.08 log CFU）、玻璃（7.51±0.26 log CFU）、聚乙烯（7.66±0.30 log CFU）、聚丙烯（7.76±0.30 log CFU）和木材（8.02±0.33 log CFU）。在所有材料上存在生物膜的情况下，消毒剂的效果显著降低。在四种不同的化学消毒剂中，氯对有划痕和生物膜的表面上的[细菌名称未给出]表现出最佳的杀菌活性。选择合适的材料、保持表面光滑以及抑制生物膜形成是食品安全的良好做法。
