Can Jews eat brie

Jews who do not follow Jewish religious laws concerning kashrut will eat brie without caring.

As for those who do observe the laws, there are many cheeses that are produced using rennet or other particulates derived from animals and are therefore not kosher. If such a cheese is produced in the same vats or areas as the brie, that will render the brie non-kosher. Most facilities that produce brie have this issue. However, brie itself can be made in a kosher way and there are some select grocers that will sell kosher brie (that was produced in unique brie-only vats).
