Root Cause
The CDC and FDA have documented multiple outbreaks of Shiga toxin-producing E. coli (STEC) linked to raw flour since 2009 (e.g., 2016 E. coli O121 outbreak in 24 states); flour is a raw agricultural product that is not treated to kill pathogens, and the low water activity of dry flour does not prevent bacterial survival; even without eggs, raw dough poses a risk of E. coli and Salmonella from flour itself.

美国疾病控制与预防中心（CDC）和美国食品药品监督管理局（FDA）自2009年以来记录了多起与生面粉相关的产志贺毒素大肠杆菌（STEC）暴发（例如2016年24个州的大肠杆菌O121暴发）；面粉是未经处理以杀死病原体的原始农产品，干面粉的低水分活性并不能阻止细菌存活；即使不含鸡蛋，生面团也存在面粉本身带来的大肠杆菌和沙门氏菌风险。

90% success Heat-treat flour before using in raw dough: spread flour on a baking sheet, bake at 350°F (175°C) for 5-7 minutes, let cool completely, then use. This kills E. coli and Salmonella. Example: 'Place 2 cups all-purpose flour on a rimmed baking sheet, bake at 350°F for 6 minutes, stirring halfway; cool to room temperature (about 15 minutes) before mixing into dough.'

95% success Use a commercially available heat-treated flour specifically labeled for raw consumption (e.g., Pillsbury's heat-treated flour or King Arthur's 'Bake for Good' flour). These are pre-treated and safe to eat raw. Example: 'Purchase a bag of heat-treated flour from a grocery store; use it 1:1 in any no-egg cookie dough recipe.'

85% success Make edible cookie dough using alternative flour substitutes that are heat-treated or cooked, such as oat flour (toasted) or almond flour (which is typically blanched and roasted). Example: 'Toast rolled oats in a dry skillet over medium heat for 3-4 minutes, then grind into flour in a food processor; use in place of wheat flour.'

中文步骤
在用于生面团之前热处理面粉：将面粉铺在烤盘上，在350°F（175°C）下烘烤5-7分钟，完全冷却后使用。这可以杀死大肠杆菌和沙门氏菌。示例：'将2杯通用面粉放在带边的烤盘上，在350°F烘烤6分钟，中途搅拌一次；冷却至室温（约15分钟），然后混入面团。'
使用市售的专门标明可生食的热处理面粉（例如Pillsbury的热处理面粉或King Arthur的'Bake for Good'面粉）。这些是经过预处理的安全生食面粉。示例：'从杂货店购买一袋热处理面粉；在任何无蛋饼干面团食谱中1:1替代使用。'
使用替代面粉替代品制作可食用饼干面团，这些替代品经过热处理或烹饪，例如燕麦粉（烘烤过）或杏仁粉（通常经过漂白和烘烤）。示例：'在干平底锅中用中火烘烤卷燕麦3-4分钟，然后在食品加工机中研磨成粉；用于替代小麦粉。'
Dead Ends
Common approaches that don't work:
-
60% fail
User thinks microwave or oven toasting flour kills bacteria; toasting at 350°F for 5 minutes may not reach all parts of the flour; heat treatment must reach 165°F throughout, which can cause flour to brown or burn if not done carefully.
-
55% fail
User believes organic or 'natural' flour is safer; organic flour is not treated differently and can carry the same pathogens from field contamination (e.g., animal manure used as fertilizer).
-
65% fail
User assumes refrigerating dough kills bacteria; refrigeration below 40°F only slows bacterial growth, does not kill E. coli or Salmonella; freezing also does not eliminate them.
