There are three categories of Kosher food - Meat, Dairy and Parve (or Pareve). The laws of kashrut pertaining to these derive from various passages in the Torah, and are numerous and complex, but the key principles can be summarized.
Only meat from particular species is permissible. Mammals that both chew their cud (ruminate) and have cloven hooves can be kosher. Animals with one characteristic but not the other (the camel, the hyrax and the hare because they have no cloven hooves, and the pig because it does not ruminate) are specifically excluded (Leviticus 11:3-8).89 In 2008, a rabbinical ruling determined that giraffes and their milk are eligible to be considered kosher. The giraffe both has split hooves and chews its cud, characteristics of animals considered kosher. Findings from 2008 show that giraffe milk curdles, meeting kosher standards. Although kosher, the giraffe is not slaughtered today because the process would be very costly. Giraffes are difficult to restrain, and their use for food could cause the species to become endangered.
Non-kosher birds are listed outright (Deuteronomy 14:12-18) but the exact zoological references are disputed and some references refer to families of birds (24 are mentioned). The Mishnah13 refers to four signs provided by the sages.14 First, a dores (predatory bird) is not kosher. Additionally, kosher birds possess three physical characteristics: an extra toeclarification needed, a zefek (crop,) and a korkoban (gizzard) with a peelable lumen. However, individual Jews are barred from merely applying these regulations alone; an established tradition (masorah) is necessary to allow birds to be consumed, even if it can be substantiated that they meet all four criteria.15 The only exception to this is turkey. There was a time when certain authorities considered the signs enough, so Jews started eating this bird without a masorah because it possesses all the signs (simanim in Hebrew) and there is a place for thisclarification needed in Jewish law.citation needed
Fish must have fins and scales to be kosher (Leviticus 11:9-12). Shellfish and other non-fish water fauna are not kosher.
Insects are not kosher, except for certain species of kosher locust (unrecognized in almost all communities).
That an animal is untamed does not preclude it from being kosher, but a wild animal must be trapped and ritually slaughtered (shechted) rather than killed some other way to be kosher. Generally any animal that eats other animals, whether they kill their food or eat carrion (Leviticus 11:13-31), is not kosher, as well as any animal that was partially eaten by other animals (Exodus 22:30/Exodus 22:31).
Meat and milk (or derivatives) cannot be mixed (Deuteronomy 14:21) in the sense that meat and dairy products are not served at the same meal, served or cooked in the same utensils, or stored together. Observant Jews have separate sets of dishes, and sometimes different kitchens, for meat and milk, and wait anywhere between one and six hours after eating meat before consuming milk products.
Examples of cloven hooves in goats (upper left), pigs (lower left) and cattle (lower right). But horses lack cloven hooves (upper right).Mammals and fowl must be slaughtered in a specific fashion: slaughter is done by a trained individual (a shochet) using a special method of slaughter, shechita (Deuteronomy 12:21). Among other features, shechita slaughter severs the jugular vein, carotid artery, esophagus and trachea in a single continuous cutting movement with an unserrated, sharp knife, avoiding unnecessary pain to the animal. Failure of any of these criteria renders the meat of the animal unsuitable. The body must be checked after slaughter to confirm that the animal had no medical condition or defect that would have caused it to die of its own accord within a year, which would make the meat unsuitable.19 As much blood as possible must be removed (Leviticus 17:10) through the kashering process; this is usually done through soaking and salting the meat, but organs rich in blood (the liver) are grilled over an open flame.
Utensils used for non-kosher foods become non-kosher, and make even otherwise kosher food prepared with them non-kosher. Some such utensils, depending on the material they are made from, can be made suitable for preparing kosher food again by immersion in boiling water or by the application of a blowtorch. Food prepared by Jews in a manner that violates the Shabbat (Sabbath) may not be eaten until the Shabbat is over.
Kosher is not a person, so it can't eat anything. But the blood of mammals and birds is not kosher, so people who keep kosher can't eat it.
Hindus do not eat beef no matter if it is Kosher or non-kosher.
They can eat a kosher diet, and be slaughtered the kosher way.
Jews are only able to eat kosher food because it is against their religion to eat non kosher food.
Anything that's kosher.
Yes, basil is kosher.
Christianity does not require kosher foods.
Jews who eat non-kosher food are in violation of the laws of their religion.
When it comes to meats, Kosher is not synonymous with Halal, so no, we cannot eat Kosher Gelatin. Gelatin is considered kosher by many Jews regardless of its source of origin. For Muslims, if gelatin is prepared from swine or cows that are not dhabeeha, it is haraam.
No, shell fish such as prawns are not kosher.
Religiously observant Jews will only eat kosher food.
Jewish Germans eat kosher food. Like in other countries though, many products that are sold in grocery markets have kosher certification.
