Non-kosher animals include pig, camel, and rabbit. Fowl such as chicken, turkey, certain duck, and certain goose are kosher. These may not be eaten in combination with meat or fowl. All fruits, grains, and vegetables in their natural state are kosher and parve. Fish that have fins and scales are kosher and parve.
Some examples are salmon, flounder, and halibut.
Examples of non-kosher fish are shark, sturgeon, catfish, and swordfish. All reptiles, shellfish, and underwater mammals, and most insects, are not kosher. The requirement to separate meat and dairy products applies not only to food, but also to the utensils used for storing, preparing, and serving these foods. Therefore, completely separate sets of pots, dishes, cutlery, etc., are standard in a kosher kitchen. There is a waiting period after eating meat before eating dairy, six hours in most communities.
