Prāyaścitta-vidhāna: Tapas, Dāna, Vrata, and Proportional Expiation (प्रायश्चित्तविधानम्)
सुरानुगतमुच्छिष्टमभोज्यं शेषितं च यत् । “बायें हाथसे लाया अथवा परोसा गया अन्न, बासी भात, शराब मिला हुआ, जूठा और घरवालोंको न देकर अपने लिये बचाया हुआ अन्न भी अखाद्य ही है
surānugatam ucchiṣṭam abhojyaṁ śeṣitaṁ ca yat |
ヴィヤーサは言った。酒などの酩酊をもたらすものに触れて汚れた食、食べ残しや不浄となった食（ucchiṣṭa）、そして他者に先に供したのち自分のために取り置いた食—それらは食すべからざるものと見なされる。ここに説かれるのは清浄と自制、そして家族や扶養すべき者より己の口腹を先にしないという倫理である。

Educational Q&A
One should avoid food that is ritually/ethically impure—especially food tainted by intoxicants, leftovers/defiled remnants, and food selfishly reserved for oneself before serving others—because right conduct (dharma) includes purity, restraint, and consideration for dependents.
In Śānti Parva’s instruction on dharma and proper conduct, Vyāsa enumerates categories of food deemed unfit to eat, using dietary discipline as a practical expression of ethical living.
