Understanding kosher Food Meaning begins with knowing which animals and foods qualify.

Fish must have fins and scales to be kosher, so salmon and tuna are allowed, while shellfish like shrimp are not. https://koshercertificationsin-wdqrj.wordpress.com/2025/08/11/kosher-what-is-the-meaning-of-kosher-food/
