Slaughter-blood of cattle, of beasts, or of fowl, whether unclean or clean; blood [shed as a result] of piercing; or blood [shed as a result] of tearing; or the blood of bloodletting, by which life escapes — they are liable for it. The blood of the spleen; the blood of the heart; the blood of eggs; the blood of fish; the blood of locusts; or the blood that oozes out — they are not liable for it. R’ Yehudah holds [one] liable for the blood that oozes out.
