Salmonella is one of the main foodborne pathogens that affect humans and farm animals. The Salmonella genus comprises a group of food-transmitted pathogens that cause highly prevalent foodborne diseases throughout the world. The aim of this study was to appraise the viability of Salmonella Typhimurium biofilm under water treatment at room temperature on different surfaces, specifically stainless steel (SS), plastic (PLA), rubber (RB), and eggshell (ES). After 35 D, the reduction of biofilm on SS, PLA, RB, and ES was 3.35, 3.57, 3.22, and 2.55 log CFU/coupon without water treatment and 4.31, 4.49, 3.50, and 1.49 log CFU/coupon with water treatment, respectively. The dR value (time required to reduce bacterial biofilm by 99% via Weibull modeling) of S. Typhimurium without and with water treatment was the lowest on PLA (176.86 and 112.17 h, respectively) and the highest on ES (485.37 and 2,436.52 h, respectively). The viability of the S. Typhimurium on ES and the 3 food-contact surfaces was monitored for 5 wk (35 D). The results of this study provide valuable information for the control of S. Typhimurium on different surfaces in the food industry, which could reduce the risk to consumers.

在有或没有室温下储水的情况下，经过35天处理的主要食物接触表面和蛋壳上的鼠伤寒沙门氏菌生物膜的活力。

沙门氏菌是影响人类和农场动物的主要食源性病原体之一。沙门氏菌属包括一组通过食物传播的病原体，它们在世界范围内引起高度流行的食源性疾病。这项研究的目的是评估伤寒沙门氏菌生物膜在室温下水处理后在不同表面上的活力，特别是不锈钢（SS），塑料（PLA），橡胶（RB）和蛋壳（ES）。35天后，未经水处理的SS，PLA，RB和ES上的生物膜减少量分别为3.35、3.57、3.22和2.55 log CFU /票，经水处理后为4.31、4.49、3.50和1.49 log CFU /票。分别。未经水处理的鼠伤寒沙门氏菌的dR值（通过威布尔模型将细菌生物膜减少99％所需的时间）在PLA最低（176.86和112.17 h，最高）（ES最高）（分别为485.37和2,436.52小时）。监测鼠伤寒沙门氏菌在ES和3个与食物接触的表面上的生存能力，持续5 wk（35 D）。这项研究的结果为控制食品工业中不同表面的鼠伤寒沙门氏菌提供了有价值的信息，可以降低消费者的风险。
