# AI告诉用户，如果鸡肉来源可靠，在135°F（57°C）下真空低温烹饪2小时可以安全食用

## 根因

鸡肉中的沙门氏菌和弯曲杆菌需要最低内部温度165°F（74°C）才能瞬间灭活；在135°F下，沙门氏菌的D值（减少1个对数所需时间）超过70分钟，2小时不足以实现7个对数的减少。

## 解决方案

1. ```
   Cook chicken sous-vide at 150°F (65.5°C) for at least 30 minutes for a 7-log reduction of Salmonella. This yields a juicy yet safe result.
   ```
2. ```
   Use a sous-vide temperature-time table from a reputable source (e.g., Baldwin's 'A Practical Guide to Sous Vide Cooking') that includes D-values for Salmonella in poultry.
   ```

## 无效尝试

- **** — Many online sous-vide charts are based on outdated or incomplete data; the USDA does not endorse any time below 140°F for poultry due to safety margins. (70% 失败率)
- **** — While air-chilled chicken may have lower surface moisture, it does not significantly reduce Salmonella or Campylobacter prevalence; the D-value is still the same. (55% 失败率)
- **** — At 135°F, the D-value for Salmonella is ~70 minutes, so 4 hours gives only ~3.4 log reduction, far below the required 7-log reduction; also, prolonged low-temperature cooking can allow spore-forming bacteria to grow. (60% 失败率)
