UNRAVELING
the copper controversy
Lessons learned from JAVMA's first retraction in 180 years.
By Dan Su, DVM, BSM Partners | petfoodprocessing@sosland.com
In early 2024, BSM Partners made public our concerns
over an emerging nutritional debate involving a
purported link between copper levels in dog food and
the development of copper-associated hepatopathies
(CAHs). Since then, both the Association of American
Feed Control Officials (AAFCO) Pet Food Committee
and the editorial board of the Journal of the American
Veterinary Medical Association (JAVMA) have published
decisions in line with our stance, speaking directly
to the need for more thorough research on the
topic before jumping to conclusions that could ultimately
jeopardize the health and wellness of our canine
companions.
The argument first surfaced from a researcher at The
Veterinary College of Medicine at Cornell University advocating
for maximum copper levels to be set for dog

food formulations on the assumption that they were associated
with increased rates of CAH. This sparked various
conversations in the pet nutrition community about
current copper recommendations for dog food, but did
not result in a clear consensus. For example, AAFCO assembled
an expert panel to address the subject, in which
panelists determined there was not enough data to alter
current copper guidelines. In a split vote, the panel did
vote to recommend a voluntary maximum copper limit,
but the motion was ultimately voted down by AAFCO's
Pet Food Committee in early June.
In the meantime, four authors - three of whom are
scientists currently employed by Hill's Pet Nutrition -
published an article, " Sixteen years of canine hepatic
copper concentrations within normal reference ranges
in dogs fed a broad range of commercial diets, " in the
