What type of food that is considered unclean According to jewish dietary laws

Animal products

Explanation:

Certain animals may not be eaten at all, including pigs, shellfish, rabbits, and reptiles.

Mammals that have split hooves and chew their cud, (including cows, sheep, goats, bison, and deer) are kosher.

Fish must have fins and removable scales to be considered kosher.

Specific kosher bird species are listed in the Torah, but there is more ambiguity about the requirements a bird must meet to be considered kosher. Generally speaking, birds of prey are not kosher.

Milk and eggs from kosher animals are kosher. Eggs must generally be checked to ensure they do not contain blood, which is not kosher.
