Natural Balance Sweet Potato & Chicken Dry Dog food has just been voluntarily recalled, 5 lb and 28 lb. packages manufactured December 17, 2009 with a "best by" date of June 17, 20011. A random sampling tested positive for Salmonella.
Mysterious to me, the FDA pet food recall site has no listing of this (though it is voluntary, nearly all pet food recalls are voluntary). Still, here is a letter from Natural Balance Pet Foods President and CEO Joey Herrick, which was sent out on the Internet. Illnois is among the 26 states affected.
Maybe it's damage control, but Herrick does seem sincerely shaken. Like the recent Iams recall, it seems no pets were actually sickened - and the companies are being voluntarily pro-active and transparent.
