What is the word for food that Jews can't eat?

Answer 1

Religiously observant Jews will not eat any food that is not kosher. The core rules of kashrut (dietary laws) are:

* Land animals must have split hooves and chew their cud.

* Fish have to have scales and fins.

* Birds cannot be amongst those listed as forbidden in the Torah and cannot be hunters/scavengers

* Animals must be killed in a specific manner and must be free of all disease

* As much blood as possible must be removed from meat as consumption of blood is forbidden

* Dairy and meat cannot be combined in the same meal and there's a waiting period between eating one then the other.

* Orthodox Jews and some Conservative Jews will not eat certain fruits and vegetables because it's too difficult to guarantee that all bugs have been washed away (cauliflower, asparagus, and the like).

Additionally, food must be prepared and handled following kashrut. Any food that does not meet these requirements cannot be eaten by those who are religiously observant.

Answer 2

In order to be kosher, food has to be prepared according to the kosher-laws (see Deuteronomy ch.14). These are explained in detail in the Talmud-volume of Chullin.
* Meat must be from those land animals which have split hooves and chew their cud (such as beef, venison and mutton).
* Fish have to have scales and fins. Shellfish are not kosher.
* Birds cannot be among those listed as forbidden in the Torah (Deuteronomy ch.14) and cannot be hunters/scavengers. In actual practice, today we eat only those species concerning which we have a tradition that they're permitted, such as domestic chicken, geese, pigeons and turkey.

* Animals must be slaughtered in the manner specified by Jewish law and must be free of all disease. In actual practice, those who keep kosher purchase meat which is certified as having been prepared in the kosher manner.
* As much blood as possible must be removed from meat before cooking, since consumption of blood is forbidden (Leviticus ch.17). This is done at home or by the kosher butcher, through salting, soaking and rinsing.

* Dairy and meat cannot be combined in the same meal and there's a waiting period between eating one and then the other. After dairy: 1/2 hour. After meat: 6 hours for most Jewish communities.

* Fruits and vegetables should be checked to be sure they're free of bugs. Some Jews avoid cauliflower, asparagus, and the like, because of the difficulty in checking them.

Additionally, food must be prepared and handled following kashrut-laws and with kosher ingredients only. Processed foods should be labeled as having had kosher supervision during their processing. Any food that does not meet these requirements cannot be eaten by those who are religiously observant Jews.

Answer 3

Food that is not kosher, and therefore deemed not suitable for eating by religiously observant Jews, is called 'treif'.

Answer 4

You are probably asking about the words "treif" or "trafe." This comes from the Hebrew word for "torn." The Bible forbids eating meat torn from a living animal, and over the years, the word treif, in reference to food, has shifted from just one kind of non-kosher meat to any non-kosher food.
