I emailed the person listed in the original post to find out if she wrote the first warning. She did write it- here is her reply:
But after eating the foodβ¦the 6 dogs here got sick, and two died within a week of each other. Different ages and breeds. After putting it out on the internet...3 more dogs have eaten the food and died. Many just got sick. So use your judgement. But the only thing in common seems to be Kirkland Lamb and rice with exp. 2013. We are waiting to hear results on testing...but that takes time. In the meantime...this food has been sold in Nov-Dec. 2011 and is on the shelves in our homes. So to save other lives...I would warn everyone you know that feeds it.
