The following kashrus information is from the OU in response to a reader's question and posted on July 9, 2014.
The OU certifies some Kraft Cheese products, however, ONLY when they bear the OU symbol. As of now, the OU certifies the following products:
- Kraft String Cheese 2% Milk Mozzarella
- Kraft String Cheese Cracked Black Pepper
- Kraft String Cheese Jalapeno
- Kraft String Cheese Tomato Basil
It is possible more will become certified in the near future.
