Kosher

Kashrut is a set of dietary laws in Judaism that governs what foods are permitted to be eaten and how they must be prepared. The laws of kashrut are based on principles found in the Torah and the Oral Torah, and are categorized into three types: produce from the earth is always permissible, laws regarding agricultural produce have an impact on their permissibility, and the basic laws of kashrut are derived from the Torah. Over time, kashrut certification agencies have been established to ensure compliance with these laws, and the laws of kashrut have been subject to various interpretations and explanations, including philosophical, symbolic, and hygienic reasons.learn more on wikipedia
