Abstract A new bactericide comprised of two chemicals, levulinic acid and sodium dodecyl sulfate (SDS), was evaluated for its efficacy on tomatoes to reduce contamination by foodborne pathogens at pre-harvest stage. Two approaches, one as prevention and the other as the treatment, were compared on Salmonella, Shiga toxin-producing Escherichia coli (STEC), and Listeria monocytogenes contaminated tomato plants. Results obtained from inoculation studies on tomato plants confirmed that this bactericide reduced the count of Salmonella, STEC, and L. monocytogenes populations substantially (P

减少番茄上食源性病原体和微生物负荷的收获前处理

摘要 评估了一种由乙酰丙酸和十二烷基硫酸钠 (SDS) 两种化学物质组成的新型杀菌剂，评估了其对番茄在收获前阶段减少食源性病原体污染的功效。对沙门氏菌、产志贺毒素大肠杆菌 (STEC) 和单核细胞增生李斯特菌污染的番茄植株，比较了两种方法，一种是预防，另一种是治疗。从番茄植株接种研究中获得的结果证实，这种杀菌剂显着减少了沙门氏菌、STEC 和单核细胞增生李斯特氏菌的数量（P
