Halakhah for Chullin 141:34
טומאה חמורה לגר וטומאה קלה עד לכלב משום דלא חזיא לגר הוא
[it is nebelah] until it becomes unfit for a dog.<span class="x" onmousemove="('comment',' And as the undigested food if vomited out would be fit for a dog it should, according to R. Johanan, render the eater unclean immediately after sunset, nevertheless the Divine Law declares him clean obviously because unclean matter that has been swallowed cannot render unclean.');"><sup>22</sup></span>
Sefer HaChinukh
That we not eat the blood of a [domesticated] beast, a [wild] animal or a bird: That we not eat the blood of a [domesticated] beast, a [wild] animal or a bird (Keritot 20b), as it is stated (Leviticus 3:17), "And any blood you shall not eat.' And it is stated in another place (Leviticus 7:26) - "from a bird or a beast" - and a [wild] animal is included in "beast" (Chullin 71a). And the prevention of blood is repeated in many places in the Torah.
