Kashrut
Among the numerous laws that form "kashrut" are prohibitions on the consumption of certain animals (such as pork and shellfish), mixtures of meat and milk, and the commandment to slaughter mammals and birds according to a process known as "shechita". There are also laws regarding agricultural produce that might impact the suitability of food for consumption.
Food and drink prohibitions
Examples of the eating of animals that are still alive include eating live seafood, such as "raw oyster on the half shell" and ikizukuri (live fish). Sashimi using live animals has been banned in some countries. Practices such as "Ikizukuri" are prohibited in Judaism under the law forbidding unnecessary pain to animals.
