Midrash for Chullin 70:11
טומאה בחבורין שאני דמגו דמהימן אקדש מהימן נמי אתרומה
R'Huna B'Nathan raised this objection: [We have learnt:] Common food which is unclean in the second degree renders [by contact] common liquids unclean [in the first degree], and renders those who eat terumah unfit.
Sifrei Devarim
"On the earth shall you spill it as water": Just as it is permitted to derive benefit from water, it is permitted to derive benefit from blood — Just as water renders seed susceptible (of incurring tumah), so, blood. Just as water need not be covered, so blood (that of a disqualified offering which has been slaughtered) need not be covered.
