Understanding the kosher food meaning starts with knowing what foods are allowed. Only certain animals qualify as Kosher. For example, land animals must chew their cud and have split hooves — cows and sheep are kosher, but pigs are not. Fish must have fins and scales, so species like salmon and tuna are kosher, while shellfish like shrimp and lobster are not. https://koshercertificationsin-zyxno.wordpress.com/2025/08/11/kosher-what-is-the-meaning-of-kosher-food/
