Contaminated surfaces can transmit pathogens to food in industrial and domestic food-handling environments. Exposure to pathogens on food contact surfaces may take place via the cross-contamination of pathogens during postprocessing activities. Formaldehyde-based commercial sanitizers in recent years are less commonly being used within food manufacturing facilities due to consumer perception and labeling concerns. There is interest in investigating clean-label, food-safe components for use on food contact surfaces to mitigate contamination from pathogenic bacteria, including . In this study, the antimicrobial effects of two types of organic acid mixtures containing 2-hydroxy-4-(methylthio) butanoic acid (HMTBa), Activate DA™ and Activate US WD-MAX™, against when applied onto various food contact surfaces were evaluated. The efficacy of Activate DA (HMTBa + fumaric acid + benzoic acid) at 1% and 2% and Activate US WD-MAX (HMTBa + lactic acid + phosphoric acid) at 0.5% and 1% against (serovars Enteritidis, Heidelberg, and Typhimurium) were evaluated on six different material surfaces: plastic (bucket elevator and tote bag), rubber (bucket elevator belt and automobile tire), stainless steel, and concrete. There was a significant difference in the log reduction on the material surfaces due to the organic acid treatments when compared to the untreated surfaces. The type of material surface also had an effect on the log reductions obtained. Stainless steel and plastic (tote) had the highest log reductions (3-3.5 logs), while plastic (bucket elevator) and rubber (tire) had the lowest log reductions (1-1.7 logs) after treatment with Activate US WD-MAX. For Activate DA, the lowest log reductions (~1.6 logs) were observed for plastic (bucket elevator) and rubber (tire), and the highest reductions were observed for plastic (tote), stainless steel, and concrete (2.8-3.2 logs). Overall, the results suggested that Activate DA at 2% and Activate US WD-MAX at 1% are potentially effective at reducing counts on food contact surfaces by 1.6-3.5 logs.
在工业和家庭食品处理环境中，受污染的表面可将病原体传播到食品上。在食品加工后的活动中，通过病原体的交叉污染，可能会接触到食品接触表面上的病原体。近年来，由于消费者认知和标签方面的担忧，基于甲醛的商用消毒剂在食品制造设施中的使用越来越少。人们有兴趣研究用于食品接触表面的清洁标签、食品安全成分，以减轻病原菌的污染，包括……在本研究中，评估了两种含有2-羟基-4-（甲硫基）丁酸（HMTBa）的有机酸混合物Activate DA™和Activate US WD-MAX™，在应用于各种食品接触表面时对……的抗菌效果。评估了1%和2%的Activate DA（HMTBa + 富马酸 + 苯甲酸）以及0.5%和1%的Activate US WD-MAX（HMTBa + 乳酸 + 磷酸）对六种不同材料表面上的……（肠炎、海德堡和鼠伤寒血清型）的效果：塑料（斗式提升机和搬运袋）、橡胶（斗式提升机皮带和汽车轮胎）、不锈钢和混凝土。与未处理的表面相比，由于有机酸处理，材料表面的对数减少量存在显著差异。材料表面的类型也对获得的对数减少量有影响。用Activate US WD-MAX处理后，不锈钢和塑料（搬运袋）的对数减少量最高（3 - 3.5个对数），而塑料（斗式提升机）和橡胶（轮胎）的对数减少量最低（1 - 1.7个对数）对于Activate DA，塑料（斗式提升机）和橡胶（轮胎）的对数减少量最低（约1.6个对数），而塑料（搬运袋）、不锈钢和混凝土的对数减少量最高（2.8 - 3.2个对数）。总体而言，结果表明2%的Activate DA和1%的Activate US WD-MAX有可能有效地将食品接触表面上的……数量减少1.6 - 3.5个对数。
