Shechitah is killing the animals by slitting the throat with a very shape knife. This has been shown to be painless to the animals, as causing pain to living things is against Jewish law. The theory is that the shape knife cuts the carotid so that the animal loses consciousness before they are able to feel pain. By the time it is possible for the animal to feel pain it is already dead. All Vegetables and fruit are kosher.
All shellfish is treyfah.
Separate sets of crockery, cutlery and cooking utensils are used, and in an orthodox home these will be cleaned in separate sinks and kept in separate cupboards. Often to help they will be different colours. After eating meat strict Jews will wait several hours before eating dairy products. Foods which contain neither meat nor milk, fruit and vegetables, may be eaten with either meat or vegetables. These foods are known as parev or parve.
