The efficiency of combination treatment of slightly acidic electrolyzed water (SAEW) and ultraviolet light (UV) for inactivation of Salmonella enteritidis (S. enteritidis) on the surface of plastic poultry coops and other facility surfaces was evaluated in the presence of organic matter. The bactericidal activities of SAEW, UV + SAEW, and composite phenol (CP) for inactivating S. enteritidis were also compared. Moreover, a model of UV + SAEW treatment of plastic transport coops with different times and available chlorine concentrations (ACC) was developed using multiple linear regression analysis. There are differences between SAEW and CP inactivation of S. enteritidis on coops, stainless steel, and glass surfaces (P < 0.05), and there are no differences between SAEW and CP on tire surfaces (P > 0.05). Disinfection of some rough material surfaces with SAEW treatment alone under feces interference on poultry farms may need a longer treatment time and/or a higher ACC than smooth surfaces. The combined treatment of UV and SAEW showed higher inactivation efficiency of S. enteritidis compared to CP and SAEW treatment alone (P < 0.05) in pure cultures or on the facility surfaces. A complete 100% inactivation of S. enteritidis on plastic poultry coop surfaces was obtained by using UV + SAEW with an ACC of 90 mg/L for more than 70 s. The established model had a good fit that was quantified by the determination coefficient R2 (0.93) and a lack of fit test (P > 0.05). The bactericidal efficiency of UV + SAEW increased with greater ACC and increasing time. The findings of this study indicate that the combination treatment of UV and SAEW may be a promising disinfection method and could be used instead of SAEW alone, especially on rough materials in the presence of organic matter on poultry farms.

微酸性电解水和紫外线对细胞悬液和人工接种塑料家禽运输笼等设施表面的肠炎沙门氏菌去污的应用。

在有机物存在的情况下，评估了微酸性电解水 (SAEW) 和紫外线 (UV) 联合处理塑料家禽舍和其他设施表面的肠炎沙门氏菌 (S. enteritidis) 的灭活效果。还比较了 SAEW、UV + SAEW 和复合酚 (CP) 灭活肠炎沙门氏菌的杀菌活性。此外，使用多元线性回归分析建立了不同时间和有效氯浓度（ACC）的塑料运输鸡舍的UV + SAEW处理模型。SAEW和CP在鸡舍、不锈钢和玻璃表面对肠炎沙门氏菌的灭活存在差异（P < 0.05），在轮胎表面SAEW和CP之间没有差异（P > 0.05）。家禽场在粪便干扰下单独使用 SAEW 处理对一些粗糙材料表面进行消毒可能需要比光滑表面更长的处理时间和/或更高的 ACC。在纯培养物或设施表面上，与单独的 CP 和 SAEW 处理相比，UV 和 SAEW 的联合处理显示出更高的肠炎沙门氏菌灭活效率 (P < 0.05)。通过使用 ACC 为 90 mg/L 的 UV + SAEW 超过 70 秒，可完全 100% 灭活塑料家禽舍表面上的肠炎沙门氏菌。建立的模型具有良好的拟合度，通过决定系数 R2 (0.93) 和失拟检验 (P > 0.05) 进行量化。UV + SAEW 的杀菌效率随着 ACC 的增加和时间的增加而增加。
