Understanding kosher food meaning starts with knowing which foods qualify. Only certain animals are considered kosher. For land animals, they must chew their cud and have split hooves — cows and sheep are kosher, but pigs are not. Fish must have fins and scales, which means salmon and tuna are kosher, but shellfish like shrimp and lobster are not. https://koshercertificationsin-qcgjx.wordpress.com/2025/08/11/kosher-what-does-kosher-food-really-mean/
