What cereals are kosher?

Answer 1

The Union of Orthodox Synagogues certifies most of General Mills' cereals. A number of Kellogg's Cereals are also certified by other kosher organizations. In general, the best option is always to look for the Hechsher (mark) that represents a Jewish supervisory agency.

Note: A version of the cereal in one jurisdiction may be made in a kosher way and a version of the same cereal made elsewhere may not be kosher, so if you are traveling or living abroad (from the USA or Israel), make sure the cereal is still kosher.

Answer 2

Post does produce some kosher cereals. You would have to check the package labeling for a valid kashrut certification symbol to determine if specific products are kosher.

Answer 3

Grain is inherently kosher. Once you make something like breakfast cereal from grain (mixing it with other ingredients and cooking it), you can make it non-kosher depending on the ingredients and how you cook it. Commercial products like commercially prepared breakfast cereals are assumed to be non-kosher unless the manufacturing facility is properly supervised. Manufacturers who have obtained such supervision mark their product with the supervising organizations mark. So, look on the box of cereal for the mark of a kosher supervisor. The OU mark (with the u inside the o) is the mark of the biggest North-American kosher certification organization. There are many others, including regional and local marks. People who keep kosher typically know the marks that matter.
