Salmonella is the most common pathogen in poultry associated to foodborne outbreaks. There is concern about the use of sodium hypochlorite (NaClO) during antimicrobial interventions in broiler chicken processing because of trihalomethane (THM) generation through oxidation of organic matter. In this study, we showed the effectiveness of neutral electrolyzed water (NEW) in broiler chickens, and their physicochemical properties after antimicrobial intervention. Neutral electrolyzed water showed 10 times higher antimicrobial effect on Salmonella pure culture than NaClO treatments but similar results were achieved on inoculated chicken carcasses. The mechanism of action of NEW was revealed by microscopic studies, showing cell swelling and morphologic changes on membrane. Neutral electrolyzed water was effective in reducing total viable counts and coliforms on broiler chicken carcasses, without color and pH modification. No THM were detected on chicken meat using 50 mg/L of either antimicrobial agents but when using higher concentration, THM were generated. Only 0.037 ± 0.001 μg/kg of chloroform was detected after ≥100 mg/L NEW treatments, whereas bromoform and chlorodibromomethane were generated after similar concentration of NaClO treatments. Neutral electrolyzed water represents a safe alternative for antimicrobial broiler chicken intervention owing to competitive production cost, safe handling, low corrosion capacity, and low toxicity because of lack of by-product generation.

沙门氏菌是与食源性暴发相关的家禽中最常见的病原体。由于通过有机物氧化生成三卤甲烷（THM），因此在肉鸡加工过程中的抗菌干预过程中使用次氯酸钠（NaClO）引起了人们的关注。在这项研究中，我们显示了中性电解水（NEW）在肉鸡中的有效性，以及经过抗菌干预后的理化性质。中性电解水对沙门氏菌的抗菌作用高10倍纯培养比氯化钠处理要好，但接种鸡的尸体却获得了相似的结果。微观研究揭示了NEW的作用机理，表明细胞肿胀和膜上的形态变化。中性电解水可有效减少肉鸡鸡尸体的总存活数和大肠菌群，而无需改变颜色和pH。使用50 mg / L的任一种抗菌剂在鸡肉上均未检测到THM，但当使用更高浓度时，会生成THM。≥100 mg / L NEW处理后，仅检测到0.037±0.001μg/ kg氯仿，而类似浓度的NaClO处理后会生成溴仿和氯二溴甲烷。由于具有竞争力的生产成本，中性电解水是抗菌肉鸡干预的安全替代品，
