Kosher

Kosher=Food which fits the Jewish dietary requirements and Jews are allowed to eat

Treyfah=Food which Jews are not allowed to eat

In Leviticus, it says

• All plants are Kosher, but not all animals, birds or fish are
• Animals must also be killed in a special manner and have all the blood removed before the meat can be eaten by Jews.

How are animals killed?

• Jews may only eat animals and birds that have been killed by Shechitah.
• Shechitah is killing the animals by slitting the throat with a very sharp knife.
• This had been shown to be painless to the animals, as causing pain to living things is against Jewish Law
• The theory is that the sharpe knife cuts the carotid so that the animal loses consciousness before they are able to feel pain.

All vegetables and fruit and dairy products are kosher
A Kosher kitchen

• Jews who keep Kosher kitchens do not eat meat and dairy foods together. 
• Seperate sets of crockery, cutlery and cooking utensils are used.
• After eating meat strict Jews will wait several hours before eating dairy products.
