Interesting. Maybe in the age of Obama the FDA's two staffers in the Centre for Veterinary Medicine (yes there are only two people working in that department) feel emboldened enough to start holding pet food companies to account.
That's doesn't change the fact that there are many regulatory changes and legal changes needed to reign the industry in. Governments in Canada and the US need the power to issue product recalls. Shockingly there is nothing in the law in either country that allows either government to do this.
