与非抗菌肥相比,抗菌肥显著减少了手上的大肠杆菌和冲洗水中的大肠杆菌. 虽然细菌转移到刀柄是相似的,但抗菌肥在食品处理场景中提供了优越的病原体去除.
科学领域:
- 微生物学 微生物学
- 公共卫生 公共卫生
- 食品安全 食品安全
背景情况:
- 手部卫生对于防止病原体传播至关重要.
- 在食品处理环境中,抗菌 (AB) 和非抗菌 (non-AB) 肥的有效性需要详细评估.
- 大肠杆菌 (E. coli) 是一种常见的病原体,与食物传播疾病有关.
研究的目的:
- 评估AB和非AB肥对手上的大肠杆菌去除的影响.
- 评估洗后的细菌从手上转移到食品处理表面的情况.
- 为了比较不同AB肥与非AB肥的杀菌和去除效果.
主要方法:
- 被大肠杆菌 (10^7-10^9 CFU) 污染的手被洗了30秒.
- 洗剂包括水,非AB肥或AB肥 (氧烯醇,二,基酸盐).
- 测量了洗手后手上的大肠杆菌减少,冲洗水中的细菌数量以及转移到聚合物刀柄上的细菌数量.
主要成果:
- AB肥实现了平均4.19-4.35Log10降低手上的大肠杆菌,明显高于非AB肥 (平均3.65Log10).
- 与非AB肥 (8.62-8.88 Log10 CFU/mL) 相比,AB肥洗的冲洗水中的细菌数量显著降低 (5.37-6.90 Log10 CFU/mL).
- 对刀柄的细菌转移在AB和非AB肥组之间没有显著差异.
结论:
- 与非抗菌肥相比,抗菌肥在减少手上的大肠杆菌和冲洗水中的效率更高.
- 该研究强调了在食品处理环境中,显著的性能差异有利于AB肥.
- 研究结果强调了适当的手部卫生产品对于提高食品安全的重要性.

Handwashing II: Pre-procedure and Initial Procedure Steps
The hand washing procedure itself includes the following steps. First, cover cuts, if any, on hands with a waterproof dressing. Cuts and abrasions can become contaminated with bacteria hindering the ability to clean the area thoroughly. In addition, repeated hand washing can worsen an injury. The nails must be short and clean, without nail...
Cleaning, Sterilization, and Disinfection
Cleaning
The cleaning process usually involves using water with detergents or enzymatic cleaner and removing foreign material from objects and surfaces, including organic material such as body fluids or inorganic material like soil. Cleaning is performed before high-level disinfection and sterilization because foreign materials on the cover of the devices interfere with process...
