Following finalisation of the ACMSF report in June 2016, the Food Standards Agency (FSA) and Food Standards Scotland (FSS) have reviewed their consumer advice taking into account the independent committee’s conclusions and recommendations. It is proposed that the FSA and FSS will continue to advise that all raw, soft-boiled hen eggs or foods containing lightly cooked hen eggs are unlikely to lead to illness in people who are in good health (who are not in a vulnerable group).
In addition, we will no longer advise against the consumption of raw and lightly cooked eggs by vulnerable groups provided that they are produced under the Lion code quality assurance scheme. This advice does not include severely immunocompromised individuals.

发现自己的方法有一个不小的漏洞,需要在这里做一下特别的补充说明。
我之前和大家分享的方法主要是基于下面这份权威的鸡蛋消毒指南:
里面指出在 140 F / 60 C 时,可以基本杀死沙门氏菌所需的时间约为 4 分钟。然而,我没有意识到这实际是指去了壳的鸡蛋。
对于带壳的鸡蛋,要让鸡蛋中心也达到所需温度,在 140 F / 60 C 时,大约需要 20 分钟。而这个时候,蛋白已经开始凝结。如果只需要流动的蛋黄,可以考虑采用这个温度。
要想最大程度的杀死所有可能的细菌,又不让鸡蛋凝结,则需要用更低的温度和更长的时间才可能达到。在 136 F / 58 C 时,大约需要 40 分钟的时间。这个时候鸡蛋不会完全凝结,但是蛋白已经开始变性。
最低可以使用的温度是 130 F / 54 C,需要差不多 110 分钟。如此长时间的温度控制,一般需要通过可靠的 Sous Vide 装置,才可能实现。

真全面。看样子得买个食物温度计了,以前做不用烤的蛋糕加蛋都是直接加生蛋了…
