简单疹病毒1型 (HSV-1) 可以在食品表面持续超过24小时,构成潜在的风险. 这项研究研究了HSV-1在各种材料和食品上的生存率,突出了传播可能性.
科学领域:
- 食品安全 食品安全
- 病毒学 病毒学
- 公共卫生 公共卫生
背景情况:
- 简单疹病毒1型 (HSV-1) 导致广泛的,无法治愈的感染.
- 虽然HSV-1通常不被认为是食物传播病毒,但在食物和表面上已经检测到HSV-1.
研究的目的:
- 为了确定HSV-1在各种与食品相关的表面和食品矩阵上的持久性.
- 评估HSV-1从表面传染到手套的可能性.
- 为了评估温度和pH值对HSV-1传染性的影响.
主要方法:
- 在不钢,玻璃和聚烯等材料上,以及在食品 (奶酪,坚果,果皮) 和饮料 (可乐,果汁,咖啡,牛奶) 上,在不同温度 (-20°C至37°C) 下测试了HSV-1的持久性,长达7天.
- 在Vero细胞上的斑块测试被用来量化病毒感染力.
- 在环境条件下评估了从不钢到酸盐和乳手套的可转移性.
主要成果:
- 在所有测试的表面上,HSV-1的传染性至少持续了24小时,在食品矩阵上至少持续了1小时.
- 病毒在可乐软饮料中迅速失活.
- 温度和pH值显著影响HSV-1感染力.
- 在特定的压力和接触时间下,HSV-1 转移到乳手套中,特别是在湿时.
结论:
- HSV-1可以在与食物相关的表面上持续存在,这表明存在潜在风险.
- 与感染HSV-1的个人共享食物可能会造成传染风险.
