UPDATED 4/7: The original author of the Blue Buffalo menadione concern wrote us today to let us know of other information supporting their position: A response from Blue Buffalo on when they would remove menadione.
ORIGINAL: This is the story that got one of our good friends, Howl911, threatened by a lawer. Read about that here.Blue Buffalo’s dog food and treats contains menadione, a substance banned by the US in 1963. The Dog Food Project, which first reported on this says:
I keep hearing from people who called Blue Buffalo customer service to ask about menadione, telling me that the representative claimed they were “required by law” to include it, which is simply not true. Menadione also still appears on ingredient lists throughout Blue Buffalo’s website and on product packaging.
Wikipedia cites problems with the use of menadione in high doses and in supplements. The question we’d like to ask Blue Buffalo is, why use a substance like this at all in pet food? How do we know this is safe for our small pets?
