## 根因

羊肉肌肉中的弓形虫包囊需要内部温度达到152°F（67°C）才能灭活；145°F且无3分钟静置可能无法杀死所有包囊，尤其对于较厚切块。

## 解决方案

1. ```
   Cook lamb to 152°F (67°C) internal temperature for at least 15 seconds, verified with an instant-read thermometer in the thickest part away from bone.
   ```
2. ```
   Cook lamb to 145°F (63°C) and let rest for 3 minutes before serving, ensuring the temperature stays above 145°F during rest.
   ```

## 无效尝试

- **** — 145°F is the USDA minimum for whole cuts of lamb but assumes a 3-minute rest; without it, the temperature may not hold long enough to kill Toxoplasma. (85% 失败率)
- **** — Relying on carryover cooking (temperature rise after removal) is inconsistent for thin chops. (70% 失败率)
- **** — Using a meat thermometer inserted near the bone gives false high readings. (60% 失败率)
