Marine oils and fats are considered kosher if sourced from what?

Marine oils and fats are considered kosher if they are sourced from kosher fish. In Jewish dietary laws, which dictate what is permissible (kosher) to consume, fish must have both fins and scales to be deemed kosher. This means that for marine oils and fats to be acceptable, they must originate from fish that meet these criteria.

Kosher fish such as salmon, tuna, and herring have both fins and scales, making their oils and fats suitable for consumption according to kosher dietary guidelines. The concept of kosher extends beyond the flesh of the animal to include byproducts like oils, thus reinforcing the importance of the source from which these oils are derived.

Freshwater fish are also considered kosher, but they still need to meet the criteria of having fins and scales. Fishmeal typically refers to ground fish that may not meet the kosher requirements if it derives from non-kosher species. Shellfish, on the other hand, is not considered kosher at all, as it lacks fins and scales, making it entirely unsuitable according to Jewish law.
