These mitzvot are explained in the ensuing chapters.

It is a positive commandment to know the signs that distinguish between domesticated animals, beasts, fowl, fish, and locusts that are permitted to be eaten and those which are not permitted to be eaten,1 as [Leviticus 20:25] states: "And you shall distinguish between a kosher animal and a non-kosher one, between a non-kosher fowl and a kosher one." And [Leviticus 11:47] states: "To distinguish between the kosher and the non-kosher, between a beast which may be eaten and one which may not be eaten."

The signs of a [kosher] domesticated animal and beast are explicitly mentioned in the Torah.2 There are two signs: a split hoof and chewing the cud. Both are necessary.

Any domesticated animal and beast that chews the cud does not have teeth on its upper jaw-bone. Every animal that chews the cud has split hoofs except a camel.3 Every animal that has split hoofs chews the cud except a pig.

Therefore if a person finds an animal whose hoofs are cut off in the desert and he cannot identify its species, he should check its mouth. If it does not have teeth on its upper jaw, it can be identified as kosher, provided one can recognize a camel.4 If a person finds an animal whose mouth is cut off, he should check its hooves, if they are split, it is kosher, provided he can recognize a pig.5

When both its mouth and its hoofs are cut off, he should inspect the end of its tail after he slaughters it.6 If he discovers that [the strings of] its meat extend both lengthwise and widthwise,7 it is kosher, provided he can recognize a wild donkey. For [the strings of] its meat also extend both lengthwise and widthwise.8

When a kosher animal gives birth to an offspring resembling a non-kosher animal, it is permitted to be eaten even though it does not have split hoofs or chew the cud, but instead, resembles a horse or a donkey in all matters.9

When does the above apply? When he sees it give birth. If, however, he left a pregnant cow in his herd and found an animal resembling a pig dependent on it, the matter is doubtful and [the young animal] is forbidden to be eaten. [This applies] even if it nurses from [the cow], for perhaps it was born from a non-kosher species, but became dependent on the kosher animal.10

When a non-kosher animal gives birth to an offspring resembling a kosher animal, it is forbidden to be eaten. [This applies] even if it has split hoofs and chews its cud and resembles an ox or a sheep in all matters. [The rationale is that offspring] produced by a non-kosher animal are not kosher11 and those produced by a kosher animal are kosher.

For this reason, a non-kosher fish found in the belly of a kosher fish is forbidden, and a kosher fish found in the belly of a non-kosher fish is permitted, for they did not produce the fish, but instead, swallowed it.

When a kosher animal gives birth to an offspring that has two backs and two backbones12 or such a creature is discovered within [an animal that was slaughtered], it is forbidden to be eaten. This is what is meant by the term hashisuah which is forbidden by the Torah, as [Deuteronomy 14:7] states: "These may not be eaten from those which chew the cud and have split hoofs, the shisuah...", i.e., an animal that was born divided into two animals.

Similarly, when [a fetus] resembling a fowl is found within a [slaughtered] animal, it is forbidden to be eaten. [This applies] even if it resembles a kosher fowl. [For when a fetus] is discovered in an animal, only one which has a hoof is permitted.13

There are no other domesticated animals or wild beasts in the world that are permitted to be eaten except the ten species mentioned in the Torah. They are three types of domesticated animals: an ox, a sheep, and a goat, and seven types of wild beasts: a gazelle,14 a deer, an antelope, an ibex, a chamois, a bison, and a giraffe. [This includes the species] itself and its subspecies, e.g., the wild ox and the buffalo are subspecies of the ox.15

All of these ten species and their subspecies chew the cud and have split hoofs. Therefore, a person who recognizes these species need not check neither their mouths,16 nor their feet.

Although all these species are permitted to be eaten, we must make a distinction between a kosher domesticated animal and a kosher wild beast. For the fat of a wild beast is permitted to be eaten and its blood must be covered.17 With regard to a kosher domesticated animal, by contrast, one is liable for kerais for partaking of its fat18 and its blood need not be covered.

According to the Oral Tradition, these are the distinguishing signs of a [kosher] wild beast: Any species that has split hoofs, chews its cud, and has horns which branch off like those of a gazelle are certainly kosher wild beasts. [The following laws apply with regard to] all those whose horns do not branch off: If they are curved, like the horns of an ox, notched, like the horns of a goat, but the notch should be embedded within them, and spiraled, like the horns of a goat,19 it is a kosher wild beast. Its horns, however, must have these three signs: They must be curved, notched, and spiraled.

When does the above apply? With regard to a species that he does not recognize. [Different rules apply with regard to] the seven species mentioned in the Torah. If he recognizes this species, he may partake of its fat and is obligated to cover its blood, even one does not find any horns on it at all.

A wild ox is a species of domesticated animal.20 A unicorn21 is considered a wild beast even though it has only one horn.22

Whenever we have a doubt whether an animal is a domesticated animal or a wild beast, its fat is forbidden, but lashes are not given for partaking of it, and we must cover its blood.23

A mixed species that comes from the mating of a kosher domesticated animal and a kosher wild beast is called a koi. Its fat is forbidden, but lashes are not given for partaking of it, and we must cover its blood.24 A non-kosher species will never be impregnated by a kosher species.25

The distinguishing signs of a kosher [species of] fowl are not mentioned explicitly by the Torah. Instead, the Torah mentions26 only the non-kosher species. The remainder of the species of fowl are kosher. There are 24 forbidden species. They are:

Whoever is knowledgeable with regard to these species29 and their names30 may partake of any fowl from other species.31 A kosher species of fowl may be eaten based on tradition, i.e., that it is accepted simply in that place that the species of fowl is kosher.32 A hunter's word is accepted if he says: "The hunter who taught me told me33 that this fowl is permitted," provided that [teacher] has an established reputation as being knowledgeable with regard to these species and their names.

Whoever does not recognize these species and does not know their names must check according to the following signs given by our Sages: Any fowl that attacks with its claws34 and eats is known to be among these species and is unkosher. If [a fowl] does not attack with its claws and eat, it is kosher if it possesses one of the following signs: a) it has an extra claw,35 b) a crop;36 this is also referred to as a mur'ah, c) [the membrane of] its craw37 can be peeled by hand.38

[The rationale is that] there are none of the forbidden species that do not attack with its claws and eat and possesses one of these three signs with the exception of the ossifrage and the osprey. And the ossifrage and the osprey are not found in settled areas, but rather in the deserts of the distant islands that are very far removed to the extent that are located at the ends of the settled portions of the world.

If its craw can be peeled with a knife, but cannot be peeled by hand and it does not possess any other sign even though it is not a bird of prey, there is an unresolved doubt regarding the matter.39 If the membrane was firm and tightly attached, but [the craw] was left in the sun and it became looser [to the extent that] it could be peeled by hand, [the species] is permitted.

The Geonim said that they have an existing tradition that one should not rule to permit a fowl that possesses only one of these signs unless that sign is that its craw can be peeled by hand. If, however, it cannot be peeled by hand, it was never permitted [to be eaten] even if it possesses a crop or an extra claw.

Whenever a bird divides its claws when a line is extended for it,40 placing two on one side and two on the other or it seizes an object in the air and eats while in the air, it is a bird of prey41 and non-kosher. Any species that lives together with non-kosher species and resembles them, is itself non-kosher.42

There are eight species of locusts which the Torah permitted:

a) a white locust,43 b) a member of the white locust family,44 the razbenit, c) the spotted grey locust, d) a member of the spotted grey locust family, the artzubiya, e) the red locust, d) a member of the red locust family, the bird of the vineyards, f) the yellow locust, g) a member of the yellow locust family, the yochanah of Jerusalem.

Whoever is knowledgeable with regard to these species and their names may partake of them. A hunter's word is accepted as [stated with regard] to a fowl.45 A person who is not familiar with them should check their identifying signs. [The kosher species] have three signs. Whenever a species has four legs, four wings that cover the majority of the length and the majority of the width of its body, and it has two longer legs to hop, it is a kosher species.46 Even if its head is elongated and it has a tail, if it is referred to as a locust, it is a kosher species.47

When [a locust] does not have wings or extended legs at present, or its wings do not cover the majority [of its body], but it will grow them later when it grows larger, it is permitted [to be eaten] at present.

There are two signs of [kosher] fish: fins and scales. Fins are used by the fish to swim and scales are those which cling48 to its entire body. Any fish that possesses scales will have fins.49 If it does not have them at present, but when it grows, it will have them or if it has scales while in the sea, but when it emerges it sheds its scales,50 it is permitted.

When a fish does not have scales that cover its entire body, it is permitted. Even if it has only one fin and one scale,51 it is permitted.
