They are Duncan Hines - I do know the difference between Duncan Hines and Betty Crocker.  I checked and re-checked.  I also checked a variety of locations in our area.  We are in Missouri.  I have called the company, but have only been able to leave a message.  So far, the lemon is still okay, but the yellow cake is not.  The company has not confirmed this, but the packaging has.  I forgot which dairy ingredient was listed on the box, but, toward the bottom of the ingredient listing, dairy is included.  I have really enjoyed the safety of their products in the past.
