根因分析
猪肉中的旋毛虫幼虫只有在145°F（63°C）下保持至少3分钟才能被杀死；如果没有静置时间，内部温度可能会降至致死水平以下，尤其是在厚切肉块中，留下存活的寄生虫。
English
Trichinella spiralis larvae in pork are killed at 145°F (63°C) only if the meat holds that temperature for at least 3 minutes; without a rest time, the internal temperature may drop below lethal levels, especially in thick cuts, leaving viable parasites.

-
将猪肉烹饪至内部温度145°F（63°C），使用食品温度计插入最厚部分测量，然后在切块或食用前静置至少3分钟。
-
对于碎猪肉，烹饪至160°F（71°C），无需静置时间；研磨将病原体分布到整个肉中。
-
使用带探头的数字即时读数温度计；插入最厚切块的中心，等待稳定读数，然后开始3分钟计时。
无效尝试
常见但无效的做法:
-
75% 失败
Assuming that 145°F is the final safe temperature without rest; USDA guidelines explicitly require a 3-minute rest for pork to ensure pathogen kill.
-
60% 失败
Using a meat thermometer only at the surface; internal temperature in thick cuts can be lower, and without rest, the heat doesn't penetrate evenly.
-
50% 失败
Believing that modern pork farming has eliminated trichinosis; while rare, outbreaks still occur (e.g., 2023 US outbreak linked to undercooked pork from a small farm).
