noun
human waste; excreta; night soil
Technical term for human feces and urine, often used in sanitation, waste treatment, and public health contexts. し尿 is the most common written form.

排泄物 is a broader term for bodily excretions, including sweat and urine, while し尿 specifically refers to feces and urine together.
糞尿 is a more direct and less technical term for feces and urine, often used in agricultural contexts (e.g., livestock waste). し尿 is preferred in official and public health discourse.
Compound of 屎 (し, 'feces') and 尿 (にょう, 'urine'). The spelling し尿 uses the kana し for the first character, likely to avoid the less common kanji 屎.
