Owner of labrador with elevated liver enzymes – unconfirmed copper liver case – calls pet food companies, asks for copper amounts on her own
As of September 1, we have emailed the press offices of Purina and Colgate Palmolive (the latter is the parent company of Hill’s) and asked them to comment on the numbers, including the more than 15 mg per kg amounts for Purina Pro Plan. We have also asked the FDA to explain why Ms. Chwastiak needed to sit on hold for hours, call up companies herself and fight for information that is clearly significant and should be on every label of every pet and human food. We have not received any immediate responses ahead of the holiday weekend. We will be going to each company Ms. Chwastiak called for comment in the coming weeks.
