Vampires, Zombies... and Kashrut!

(2) Therefore anyone who eats an olive sized portion of the meat of a non-kosher domesticated animal or wild beasts is liable for lashes according to Scriptural Law. This applies whether he partook of the meat or the fat. For the Torah did not distinguish between the meat and fat of non-kosher animals.

(3) [Regarding] humans, even though it says (Gen. 2:7): "And the human became a beast with a soul," they are not included in the category of hoofed animals. Therefore, they are not included in the [above] prohibition. Accordingly, one who partakes of meat or fat from a human - whether alive or deceased - is not liable for lashes. It is, however, forbidden [to partake of human meat] because of the positive commandment [mentioned above]. Indeed, the Torah lists seven species of kosher wild beasts and says (Lev. 11:2): "These are the beasts of which you may partake." So, everything [in this category] besides these is not eaten. And a negative commandment that comes as a result of a positive commandment is considered as a positive commandment.

It is permitted to consume human (breast)milk even though human meat is forbidden from consumption. We have already explained that this is a positive commandment.

MISHNA: A pregnant woman who smelled food [on Yom Kippur]: feed her until she recovers, as failure to do so could lead to a life-threatening situation. If a person is ill, feed them according to the advise of experts. And if there are no experts there, feed them according to their own instructions, until they say enough. GEMARA: The Sages taught: With regard to a pregnant woman who smelled consecrated meat or pig meat, one inserts a thin reed into the juice and places it on her mouth. If her mind become settled, it is well. And if not, one feeds her the gravy itself . If her mind becomes settled, it is well. And if not, one feeds her the fat of the forbidden food itself - as there is no halakha that stands in the way of saving a life except for idol worship, and forbidden sexual relationships, and bloodshed.

(11) For the life of the flesh is in the blood, and I have assigned it to you for making expiation for your lives upon the altar; it is the blood, as life, that effects expiation.

(16) But you must not partake of the blood; you shall pour it out on the ground like water.

When a person collects the blood of teeming animals and eats of it, one receive lashes [if one eats a portion] the size of an olive. [This applies] if one was warned against eating it because [it was from] a teeming animal. If, however, one is warned against eating because [of the prohibition against] eating blood, one is not liable. For we are liable only for the blood of domesticated animals, wild beasts, and fowl.

Rav Sheshet said, in the case of human blood (lit: one who walks on two legs) one is not even enjoined to refrain from it. An objection was raised: [But wasn't it taught] "the blood of the spleen, or of the heart or of the kidneys or of any other limb is subject to a prohibition; the blood of those that walk on two legs or that of reptiles and creeping things is forbidden, but one is not liable for it!" The ruling of the baraita that it is forbidden refers to the case where it had been separated, but in the instance of Rav it had not been separated; as it has been taught: "The blood found on a loaf of bread must be scraped away and the loaf may be eaten; that between the teeth may be sucked and swallowed without hesitation."

Although human milk is permitted, the Sages prohibited an adult to nurse from breasts. Instead, the woman should express it into a container and the adult should partake of it. An adult who nurses from a breast is like one who nurses from a teeming animal. They are given stripes for rebellious conduct.
