Tīrtha-vaṃśa Upadeśa: Instruction on the Fruits of Sacred Waters
निरोड्कारेण यद् भुक्तं सशस्त्रेण च भारत । दुरात्मना च यद् भुक्तं तं भागं रक्षसां विदु:
nirod-kāreṇa yad bhuktaṁ saśastreṇa ca bhārata | durātmanā ca yad bhuktaṁ taṁ bhāgaṁ rakṣasāṁ viduḥ ||
ভীষ্মে ক’লে—হে ভাৰত! যি অন্নত আগতে অনধিকাৰী/অনুমতিহীন মানুহে খাইছে, অথবা যাক অস্ত্ৰধাৰী বা দুষ্টচিত্ত মানুহে ভোগ কৰিছে—সেয়াও ৰাক্ষসসকলৰ ভাগ বুলি গণ্য হয়।

Food should be accepted only when it is obtained and approached with dharmic fitness and restraint; if it has been first consumed/handled by unauthorized, armed, or wicked persons, it is considered spiritually impure—symbolically assigned to rākṣasas—and should be avoided.
In the Anuśāsana Parva, Bhīṣma instructs Yudhiṣṭhira on dharma. Here he gives a rule about the propriety of eating: certain prior contact with food (by unfit/unauthorized, armed, or immoral persons) renders it unfit for a righteous person.
