I assume this is what you are referring to -- it was new on
kasrut.com's alerts page today:

Pinnacle Foods Corporation is recalling "Duncan Hines(r) Bakery-Style
Chocolate Chip Muffin Mix" due to undeclared milk. The product is
labeled "DUNCAN HINES(r) BAKERY-STYLE CHOCOLATE CHIP MUFFIN MIX" with
UPC Code 44209 42012, and includes Production Codes of 27166523,
27266521, 27266522, 27266523, 31266522, 31266523, 06666622, or
06666623, located on top of the carton.

In case anyone doesn't know, http://www.foodallergy.org/alerts.html
and http://www.kashrut.com/Alerts/ are excellent sources of
information about mislabelled products.  (The latter mainly deals with
cases where issues of kashrut are concerned, so products that were
never labelled as kosher would not appear there.)
