The ritual slaughtering of animals. While the practise that prevailed among the nations of antiquity other than the Hebrews, of cutting off a limb from a living animal and eating it, is condemned in several passages in the Bible (see CRUELTY TO ANIMALS; DIETARY LAWS), no definite mode of slaughter is prescribed. In connection with the preparation of an animal for sacrifice the term "sha?a?" is used (Leviticus 1:5,11; 3:2,8,13); but this denotes merely that the animal is to be killed, and not how it is to be slaughtered. There can be but little doubt, however, that in slaughtering the sacrificial animals the priests followed some uniform mode akin to that which was later adopted by all Israel and which is known as "she?i?ah" (see Sifre to Deuteronomy 12:21). Speculating on the etymology of the words "sha?a?" and "zaba?," the Rabbis endeavored thereby to establish on a Scriptural basis the law that an animal should be slaughtered by cutting the throat (?ul. 27a). The current opinion, however, was that all the laws of she?i?ah were given orally to Moses by God (ib. 28a, based on Deuteronomy 12:21). One opinion is to the effect that Moses was commanded concerning the she?i?ah of mammals only, and not concerning that of birds, the latter, therefore, being merely a rabbinic institution (ib. 27b, 28a).
The laws of she?i?ah apply only to mammals and birds, not to fishes and locusts (ib. 27b, based on Numbers 11:22). The latter, however, should not be eaten alive (Shul?an 'Aruk, Yoreh De'ah, 13, 1, Isserles' gloss). The young found in an animal which has been duly slaughtered may be eaten without the carrying out of the usual form of she?i?ah, provided it did not "step on the ground," e., if it is used for food soon after being found in its mother's womb (?ul. 74a).
The slaughtering of animals is entrusted only to persons versed in the Law and skilled in their work. She?i?ah may not be performed by the following: a deaf-mute, idiot, or minor (ib. 2a); one who is intoxicated (Yoreh De'ah, 1, 8, and Isserles' gloss); an old man whose hands tremble, it being apprehended that he may press the knife against the throat of the animal instead of gently moving it forward and backward (comp. "Be'er He?eb" and "Pit?e Teshubah," on Yoreh De'ah, 1, 5); a non-Jew, even though not an idolater (?ul. 13a, b); a Jew who spitefully transgresses the laws of Judaism ("mumar le-hak'is"; Yoreh De'ah, 2, 5; see Heresy). Some authorities considered women incompetent to perform she?i?ah (Tos. to ?ul. 2a, s. "Ha-kol"; Yoreh De'ah, 1, 1, Isserles' gloss), an opinion that came to be generally accepted.
At the present time the custom is to allow no one to slaughter unless he has passed a rigid examination before a competent authority in all the laws of she?i?ah and of ?EREFAH, especially those pertaining to the examination of the lungs, and has received a written certificate ("?abbalah") of his knowledge of such laws, of his expertness in examining the knife, and of his skill in slaughtering. Even after he has received such a certificate and has been permitted to slaughter animals, the sho?e? is enjoined to review the laws of she?i?ah occasionally (at least every thirty days), so that he may remain well versed in them (ib. 1, 1, Isserless' gloss).
The length of the knife ("?allaf") with which she?i?ah is performed must be twice the width of the throat of the animal about to be slaughtered, the maximum length being fourteen fingerbreadths (ib. 8, Isserles' gloss). The knife must be sharp, smooth, and without any perceptible notch; and it must be thoroughly examined before the slaughtering, by passing first the finger and then the finger-nail over its edge and both sides (?ul. 17b). It should be similarly examined after the slaughtering; and if a notch in it should then be found the animal becomes ritually unfit for food (ib. 10a). It is customary for the sho?e? to occasionally submit his knife to the rabbi for examination (ib. 18a). In Yoreh De'ah, 18, 17, the opinion is expressed that this examination is no longer necessary, since only pious and learned men are now appointed as sho?a?im. The custom, however, still prevails. Before slaughtering, the following blessing is pronounced: "Blessed art Thou . . . who sanctified us with His commandments and commanded us concerning slaughtering." In case many animals are to be slaughtered at the same time one blessing is sufficient. After the blessinghas been pronounced no irrelevant conversation is permitted (?ul. 86b; Yoreh De'ah, 19).
The act of slaughtering proper consists in cutting through the windpipe and the gullet in mammals, or either of these in birds. If the greater part of both these organs is cut through (or, in birds, the greater part of either), the animal is considered ritually slaughtered (?ul. 27a). The veins along both sides of the neck of a bird must be pierced at the time of slaughtering (ib.; Yoreh De'ah, 21, 22). The many details of she?i?ah were summarized by the Rabbis under the following five laws, which were supposed by them to have been delivered by God to Moses (?ul. 9b):
