GRAPES & raisins?
SNOPES & ASPCA POISON CONTROL URBAN LEGEND?

Snopes and ASPCA Poison Control say grapes are deadly to dogs but breeder survey disagrees.
Whether it could be from grapes or pesticide poisoning,
lists raisin-grape poisoning symptoms as
vomiting, diarrhea, depression, lethargy, anorexia, colic, dehydration and renal
failure (death) if untreated so seek veterinary help if your pet shows more than
two of those symptoms,
chastised for including grapes on a list of
fruits and veggies dogs appreciate
article also warned of pesticide toxicity ratings and warnings. Several
indignant emails referred us to the "deadly grapes" warning on Snopes which
references the Poison Control Center. We would have left it at that but
now there is more you
need to know about the toxicity reports associated with grapes and raisins.
First the facts and then, because this “urban legend” is so convoluted, background on the ASPCA’s Animal Poison Control Center.
No Grape or Raisin
than respond with fifty years of personal observations, we decided to ask the
world's best dog health experts! See survey results below. In
addition, we were unable to find any veterinary university study on the alleged deadly effects of
raisins or grapes. We thought that was suspiciously derelict as regards
research and a duty to protect dogs. If something so common can so easily kill so many dogs,
why would the vet schools not research it? It was then
brought to our attention that there is no profitable prevention, prescription or
antidote. Well! That explains that but it doesn’t explain how the
urban legend began or why it hasn’t been debunked until now. There
is however, an interesting theory we will share with you.
Snopes is the
brainchild of a couple who saw the need for debunking Urban Legends just
as we see the need to enlighten pet owners. So we checked Snopes as the
oft-cited source for the "deadly grapes" stories but found
only a vet’s personal assessment, a brief dissertation written by someone with
no listed veterinary credentials, and interestingly, numerous references back to APCC
which is apparently owned by the ASPCA.
(Editor's note: Feb. 22, 2011: We had reason to check the
Snopes website today. The original article we downloaded, printed,
and referenced in June 2009 has been updated and substantially
re-worded and there is now a new article, see below.)
Snopes fails to mention the
absence of autopsies or university studies; the first things researchers look
for in determining the validity of any medical report. Absent confirming
grape-raisin-poisoning autopsies or a definitive study, diagnosis could only have been based on
hearsay or a panicky owner’s recollection that, yes, it seemed like the dog
might have eaten raisins or grapes.
We are also aware that a careless owner, realizing they failed to prevent the pet (or a child’s) access
to genuinely toxic substances, would grasp any straw rather than face
self-recrimination or potential
Onions As Poisonous As Grapes?
named Barbara "killing them with kindness" Mickelson, writing for Snopes, says
"chocolate and cocoa can (also) prove deadly to them (dogs) as can onions and
Perhaps, but as with grapes, every breeder I know
who makes dog stew ads onions just as I've done for over fifty years.
Maybe cooking makes onions safe and it takes a proportionately large amount as
with chocolate, etc etc. In any case, assuming that raisins would be more toxic than grapes due to
the sulphur dioxide or other chemicals used in the curing process, we
might believe the vet is correct in stating a dog that actually “ate half
a canister of raisins” (or prunes, figs, dates, beef jerky, etc) could be
poisoned - if it was a fairly large canister.
So we surveyed 130 dog
breeders, vets, and professional handlers across the nation. We asked if
they, or anyone they knew, had experienced a case of raisin or grape toxicity.
We expected at least one confirming reply. After all, millions of dog
owners use grapes as treats and according to the “GRAPE ALERTS” now circulating the internet, ingesting even one grape could cause renal failure and
Raisin or Grape Poisoning Survey Results
We held this article for two weeks to
allow ample time for feedback. Statistically speaking,
the results were conclusive.
130 to 0, no one in our survey has ever had or
known of a dog that did more than wag and beg for more grapes!
No disrespect to the ASPCA
poison control database but TheDogPlace research is based on hundreds of years of professional dog owner experience.
But we aren’t stopping there. This article will be read by a half million
people over the next three months. We ask if anyone has verifiable information on raisin or grape
toxicity, we will add that to a follow-up report and reader comments.

Is There a Conflict Of Interest? Snopes & ASPCA Poison Control
Even more troubling, no credible report would fail to note that the ASPCA owns
the Animal Poison Control Center. The APCC is an income-producing
business. We do not imply that Snopes, APCC or ASPCA
would generate or cover up a story for any form of quid pro quo, only that it is
a serious lapse in disclosure as practiced by other media outlets.
It should however be noted that, in
addition to the Animal Poison Control Center,
which charges callers a $60 fee, ASPCA has another enterprise; ASPCA’s
Animal Product Safety Service (APSS) for pet product makers.
This means that the ASPCA’s
APSS has a close alliance with the dog food corporations whose products have
made pets sick. This quote from TheDogPress is interesting
food and other pet foods continue to make pets sick, yet ASPCA’s Animal Poison
Control Center concludes pet food recalls are “likely not food-related.”
The Animal Poison Control Center release comes at a time when dog owners
should be worried about recalled, Counterfeit
(ref #1), recycled, Toxic Pet
Foods,(ref #2) and the biggest Pet Food
(ref #3) of 2009, not grapes or raisins! Quality
Control is sloppy in the human food chain but in animal feeds, Quality
Control (ref #4) is alarmingly compromised.
This is all very
confusing and has led to yet another Urban Legend because there seems to be a
mountain covering a molehill when it comes to documenting deaths caused by
grapes. The lack of medical evidence on raisin or grape toxicity and the
inability to define what the toxic substance is causes owners to be distrustful
of real warnings.
Even more disturbing, we could find no reference in any Snopes or Poison Control
“toxic grape and raisin” report to the likelihood of
On the contrary, the APCC site displays a puzzling letter from a veterinary
toxicologist which states in part, “Why did the fruit cause the dogs to become
ill? No one knows. Suspect grapes and raisins have been screened for various
pesticides, heavy metals (such as zinc or lead), and mycotoxins (fungal
contaminants) and so far, all results have come back negative.”
That leads us right back to the article for which TheDogPlace was attacked.
Pesticide Problem Not Mentioned in Grape Toxicity Report!
When an APCC vet states that grapes caused the dog to become ill even though
"no one knows" why, it demands an answer - from Animal Poison
Control! Why doesn't the SPCA sponsor a study to find out? Even more worrisome, the
ASPCA Poison Control directly
contradicts the flood of warnings from NIH (National Institute of Health), the FDA
(Food and Drug Administration) and medical universities which stress washing all
fruits and vegetables due to high pesticide contamination.
The Environmental Working Group (EWG), a non-profit research and advocacy group,
issued a 2007 report in which the pesticide toxicity of fruits and vegetables
was ranked according to FDA data. Imported grapes were the 10th most toxic
domestic grapes ranking 21st on the list of 43,000 samples! In addition to that
compelling evidence, National Pet Press published a universally accepted list of
pesticide contaminated produce and in 2008 The Dog Place published
Produce Pesticides. (ref #5)
Therefore, when the ASPCA APCC states that no traces of pesticides could be
found on grapes, it stretches logic (and Animal Poison Control Center
credibility) to the breaking point. In fact, it is reminiscent of the
in which John Stossel asserted
that neither organic nor conventional produce samples contained any pesticide
residue. "Someone" gave him a prepared script which somehow, contained someone else's statement
(wonder how much that cost produce growers?) and our friend Stossel had to apologize.
A reasonable person would assume that dogs suffering from classic symptoms of
chemical poisoning were poisoned by the chemicals sprayed on the fruit rather
than the fruit itself. But someone who checked with Animal Poison
Control might well be given information that could jeopardize diagnosis and
thus, the dog's life.
A vet working under duress with a dog
in critical condition needs instant recall or computerized facts, not misleading
information. The emergency treatment for grape poisoning might be the same as
for any form of chemical poisoning but misdiagnosis explains why some dogs are
reported as having died from grape or raisin poisoning when it fact, the vet was
misled. Given that no component of the
grape has ever been identified as toxic to dogs, (tannins have been eliminated)
it could be grievously misleading to blame renal failure on grapes rather than
toxic sprays, pesticides, or the Lethal Chemicals
(ref #6) used to ripen fruit.
In human medicine, this would shout “cover-up” and call for an investigation. Who will speak for the dogs?
We will provide more background information on the National Animal Control
Poison Control Center in our next edition. We'll also have a little fun testing
your IQ with a question posed to the Vermont Veterinary Association, the strange
relationship between anti-freeze and deadly grapes, and other provocative ethics
questions which continue to emerge as we

Poison Control says nearly all dogs that eat (even a single serving) develop
renal failure. But the same article also states clinical signs lasted for
"several days - sometimes even weeks." Confusing and contradictory but the
message is clear. Call ASPCA Poison Control!
