Kashrut: Jewish Dietary Laws

Kashrut: Jewish Dietary Laws

Kashrut is the system of Jewish dietary laws derived from the Torah (Leviticus 11, Deuteronomy 14) and developed by rabbinic tradition over millennia. Its purpose is sanctification — transforming the daily act of eating into an act of divine service.

Kosher Animals

Land animals: Must have cloven hooves and chew cud. Cow, sheep, and goat are kosher; pig (cloven hoof but does not ruminate) and camel (ruminates but hoof not cloven) are not. Fowl: Identified by tradition — chicken, turkey, duck, and goose are kosher; birds of prey are not. Fish: Must have fins and scales — salmon, tuna, cod are kosher; catfish, eel, and shellfish are not.

Shechitah

Ritual slaughter (shechitah) is performed by a trained shochet using a perfectly sharp knife (chalef) that cuts the trachea and esophagus in a single continuous motion. This minimizes the animal's suffering. Blood must be drained and then covered with earth (kisuy dam). The animal must be healthy — any lung defect (tarah) invalidates it.

Separation of Meat and Dairy

"You shall not boil a kid in its mother's milk" (Exodus 23:19) is the basis for prohibiting mixing meat (basari) and dairy (chalavi). Requirements include:

• Separate utensils: distinct pots, pans, plates, cutlery, and appliances for meat and dairy.
• Waiting time: Ashkenazi tradition waits 6 hours between meat and dairy; Sephardic custom ranges from 1 to 6 hours depending on the community.
• Pareve: neutral foods (eggs, fruits, vegetables, grains) that may be eaten with either.

Kosher Certification

A hekhsher (certification symbol) indicates a processed product is kosher. The most recognized agencies include OU (Orthodox Union), Star-K, Kof-K, and CRC. Consumers should know the symbols and trust the agency's integrity.

Contemporary Approaches

Orthodoxy holds that kashrut is an immutable divine law (chok). The Conservative movement maintains the laws but allows modern interpretations — for example, accepting certain cheeses without certification under rabbinic supervision. The Reform movement considers kashrut optional but values its spiritual potential; many Reform Jews practice an "eco-kashrut" or "ethical kashrut" that includes considerations of food justice and sustainability.

"Sanctify yourselves and be holy, for I am the Lord your God" (Leviticus 20:7) — kashrut is a path to everyday holiness.
