In 1908, an unpublished investigation by the French government discovered a number of commercial kitchens that violated the 1903 law regarding hygiene and security in the workplace. A linear-probability model shows that restaurants in tourist neighborhoods were 12 percentage points more likely to transgress sanitary regulations than those in non-tourist areas. Many of the kitchens in the expensive restaurants of central Paris were in basements where they lacked fresh air, sunlight, and efficient waste evacuation. Clientele also mattered as a determinant of insalubrity. Local repeat customers whose loyalty depended on constant restaurant standards tended to exert more pressure on sanitation than did tourists who based their choices on culinary reputation, such as recommendations in Baedeker’s travel guide.

1908年在巴黎对餐厅卫生进行了首次系统调查

1908年，法国政府进行了一项未公开的调查，发现许多商业厨房违反了1903年关于工作场所卫生和安全的法律。线性概率模型显示，旅游街区的饭店违反卫生法规的可能性比非旅游区的饭店高12个百分点。巴黎市中心昂贵餐厅中的许多厨房都在地下室，那里缺少新鲜空气，阳光和有效的疏散废物。客户群也很重要，它决定着不溶解度。忠诚度取决于餐馆标准的本地回头客，往往比以美食声誉为基础的游客（如《 Baedeker旅行指南》中的建议）对卫生的压力更大。
