If you regularly buy food from supermarkets, you’ve probably seen the OU symbol on various products and wondered what it means. These mysterious markings are called hechsher symbols and understanding them is very important to a consumer.

We  would like to explain to you what these labels mean and where you can find them.

A hechsher is a special product certification, qualifying foods that conform to kosher requirements. Kosher-certified companies have to meet the highest standards of product quality as well as maintaining the best manufacturing practices.Hechsher certification brings strict requirements to the quality of finished products as well as their ingredients. That is why production lines and equipment used to manufacture kosher foods are thoroughly cleaned and purged. Even the smallest amount of a non-kosher substance is not allowed. Products may be rendered non-kosher if the utensils and equipment were not clean.

Kosher dietary laws identify three classifications of foods: meat, dairy, and “neutral“ foods, also called pareve. The hechsher itself isn’t a signifier of hypoallergenic foods. However, ”neutral” products are helpful to people who are allergic to dairy or meat because pareve indicates food is free of milk products and meat.


  • OU — the food contains neither meat nor dairy and is therefore a “neutral” product
  • OU-D — dairy product
  • OU-M (OU-Glatt) — the product is made with meat or meat ingredients
  • OU-F — the product is made with fish ingredients

    People who are allergic to milk or meat. Pareve products contain no meat or dairy and so they may be consumed by vegetarians and people with lactose intolerance.

    • People who are dieting or exercising regularly. Kosher products are a great choice for them.
    • People who want to be sure that they buy healthy and high-quality food.
