## 根因

美国农业部要求美国生杏仁必须经过巴氏杀菌（蒸汽、油烘烤或环氧丙烷处理）以降低沙门氏菌风险；家庭焯水（煮沸1-2分钟）可能无法达到足够的温度或时间来杀死沙门氏菌，并且只去除了表皮。

## 解决方案

1. ```
   Spread raw almonds in a single layer on a baking sheet. Roast at 350°F (177°C) for 10-12 minutes, stirring halfway through. This achieves a 5-log reduction of Salmonella. Let cool completely before storing. Use a food thermometer to ensure center reaches 165°F.
   ```
2. ```
   Look for almonds labeled 'roasted', 'dry roasted', or 'steam pasteurized' on the package. These have undergone USDA-approved treatment. Avoid 'raw' almonds unless you plan to roast them yourself.
   ```

## 无效尝试

- **** — Salmonella can survive 3 minutes at 212°F if the almonds are cold; the center may not reach lethal temperature; USDA pasteurization requires 4-log reduction, which boiling may not achieve. (80% 失败率)
- **** — Salt water does not kill Salmonella; it may actually promote bacterial growth if left at room temperature. (90% 失败率)
- **** — All almonds sold in the US must be pasteurized by law; 'raw' almonds from farmer's markets are still pasteurized (usually steam); the risk is from the pasteurization process itself, not the source. (60% 失败率)
