In English, Hebrew word kosher means "fit." The kosher laws define the foods which are fit for consumption for a Jew. Kosher law is basically a set of dietary rules about what to eat & how to eat. It also defines which food can’t be consumed (Non-Kosher). Kosher foods are those that conform to the regulations of kashrut (Jewish dietary law). Food that may be consumed according to halakha (Jewish law) is termed kosher.

When a product or establishment is certified Kosher, it signifies that an 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 Kosher logo on it signifies product as kosher.
