根因分析

单核细胞增生李斯特菌可在陈年60天的生奶奶酪中存活，尤其软熟型（布里、卡门贝尔）和表面熟成奶酪，对孕妇、老年人和免疫功能低下者构成风险。

English

Listeria monocytogenes can survive in raw milk cheese aged 60 days, especially in soft-ripened varieties (brie, camembert) and surface-ripened cheeses, posing a risk to pregnant women, the elderly, and immunocompromised individuals.

解决方案

  1. Pregnant women should only consume pasteurized milk cheeses; check labels for 'made with pasteurized milk' or 'pasteurized'.
  2. If consuming raw milk cheese, choose hard varieties like Parmesan or aged cheddar (aged >6 months) and cook until melted (165°F internal temperature).

无效尝试

常见但无效的做法:

  1. 85% 失败

    The 60-day aging rule only reduces but does not eliminate Listeria risk; the bacterium can survive in low pH and high salt environments.

  2. 80% 失败

    Scraping off the rind does not remove Listeria that penetrates into the cheese paste.

  3. 75% 失败

    Freezing raw milk cheese does not kill Listeria; it can survive and grow upon thawing.
