When a product or establishment is certified Kosher, it signifies that a establishment or a company comply with a strict policy of kosher food laws, including cleanliness, purity and quality. It is the highest standard of kosher foods, built on a deep level of trust between manufacturers, producers and consumers.
Kosher foods are the food items that follow the regulations of kashrut (Jewish dietary law). To be certified Kosher, all ingredients in every product—and the process of preparing the product—must be certified for kosher-compliance too. All the products with a KA logo on it signifies product as kosher.
