"Kosher" means proper to eat or fit for consumption. The process of making sure the food is kosher is simplified by kosher certification, Manufacturers must try to conform to the standards of kosher certification to make their products kosher. The products that are considered kosher has a label or a logo that is associated with a certain kosher certifying organization. These kosher certification process have different degrees of strictness or standards. Some have usually high standards than the others.These organizations use kosher symbols alongside with their logo like the letter D for dairy and the letter P for kosher for Passover. Usually products that have the letter D symbol has a lesser standard -"regular kosher" or non- supervised milk. The manufacturers are charged a fee for the kosher certification of their products. This fee is used for the expenses of determining the ingredients of the products and for the inspection of the facilities in production. The manufacturer benefits from the certification because their products become available to people who prefer kosher and kosher foods are globally considered to have a higher food standard. Kosher certification enhances the credibility and in the marketing of the product.
