追加:第 2 节第 46 条 发霉的粮食坚果整包扔掉(黄曲霉毒素)

2026-10-14 起草。条号 46 是占位,入库时按实际条号改。

和已有条目的分工

  • 第 2 节第 40 条(不买小作坊散装自榨花生油)管买油,已写 IARC 1 类和广州、广西两项研究。本条管家里囤的花生、玉米、坚果和米面,不重复那两项研究。
  • 第 2 节第 25 条(喝茶)备注已写茶叶霉菌毒素,本条不涉及茶。
  • 第 1 节第 48 条(家里不自制酵米面)管米酵菌酸急性中毒,是另一种毒素。
  • 第 1 节第 14 条(查乙肝两对半):本条的风险叠加主要落在乙肝携带者身上,互相指路。
  • 第 2 节第 22 条(每天吃一小把坚果):本条不是劝人别吃坚果。

全书 grep「霉变|发霉|黄曲霉」只命中第 25、40 条和第 6 节一处无关文本,没有同一动作的条目。

Aflatoxins cause cancer of the liver (hepatocellular carcinoma).」「Aflatoxins are carcinogenic to humans (Group 1).」「when HBV status was included in the analysis, a greater than multiplicative interaction between aflatoxin exposure and HBV infection was found.」「The major hosts of A. flavus among food and feed commodities are maize, peanuts, and cottonseed … tree nuts are contaminated less frequently.」

证据等级与收益量级

  • 证据等级 B:「吃进黄曲霉毒素会致肝癌」是 IARC 1 类、有前瞻性生物标志物研究支撑。但本条的动作是「家里发霉的整包扔」,没有任何研究直接测过这个动作能降多少肝癌或死亡,动作本身靠的是官方提示(农业农村部、广东省卫健委、USDA)。按 CLAUDE.md「有研究支撑但难以量化」给 B。
  • 收益量级 中(凭判断):收益栏的 3.4 倍、59.4 倍是暴露和肝癌的关系,不是本条动作的效果,机械套「≥20% 为大」不合适。另外启东的毒素标志物到 2009 年已经查不出,眼下普通家庭的暴露很可能远低于 1980 年代那批研究对象,这一点没有全国数字,是判断。乙肝携带者的叠加风险大,所以没降到小。
  • 成本标签钱=0:扔掉的是几块到几十块钱的食物,不算新增开支。

没收的

  • GB 2761 限量:第 2 节核实记录早先就记着 GB 2761-2017 原文没取到;这次也没去取,标准现行版本是否已更新也没核。本条不写限量数字,来源栏不放。
  • 香港食物安全中心「化学物危害评估-黄曲霉毒素」(https://www.cfs.gov.hk/sc_chi/programme/programme_rafs/programme_rafs_fc_01_16_report.html):有「食物如看似霉坏、潮湿、皱皮或变色,便应弃掉」「温度最好在摄氏20度以下,相对湿度在80%以下」,但页面年代很早(参考资料指向已失效的 IARC 旧 IP 地址),内地官方提示已够用,没引。
  • 「挑掉霉粒、剩下的就安全」到底差多少:没找到给家庭场景的数字。农业农村部那篇在「仓储环节」写了「剔除……霉变果」,那是入库前的分拣,不是家里吃之前挑一挑。所以条目只引官方的「整袋扔掉」「有霉味的坚决丢弃」,没有写「挑过的剩下的毒素有多少」这类数字。
  • 「毒性是砒霜的 68 倍」:两份中文官方科普都写了,但它是急性毒性比较,和慢性致癌是两回事,读者容易误读,没写。
  • 苦杏仁、桃仁的氰化物:标题里的「发苦的坚果」只指霉变带来的苦味(出自农业农村部原文)。苦杏仁是另一件事,没查来源,没写。
