Default Fluoride in pet food: The link to osteosarcoma

PAW PRINTS: Fluoride in pet food: The link to osteosarcoma

By Niki Laviolette
Special to the Tribune-Star

TERRE HAUTE — The most common type of bone cancer in dogs, cats and
humans is osteosarcoma. Osteosarcoma is more common in the larger breeds
of dogs such as Rottweilers, greyhounds, golden retrievers, etc.
Eighty-five percent of all major bone tumors in dogs and 70 percent in
cats are osteosarcoma. Approximately 5 percent of all primary bone
tumors in children are osteosarcoma-related.

A number of studies suggest a possible link between osteosarcoma and the
exposure to fluoride. According to the Environmental Working Group
(www.ewg.org), they “conclude that fluoridation of public water supplies
should stop because of risks that outweigh the possible benefits,
especially for infants and young children who consume more water than
adults, relative to their size.” The Environmental Working Group has
been concerned with healthy ingredients and the safety of pet food. EWG
pet food testing has revealed high levels of fluoride in various major
brand pet foods. Veterinarians are reporting a rise in cancer rates
found in dogs and many are wondering if diet is a contributing factor.

George Glasser, press officer/water quality adviser, National Pure Water
Association, reports, “A low-fluoride commercial dog food contains 40-60
parts per million of fluoride. A high-fluoride dog food can contain up
to 460 parts per million of fluoride.” A study at the University of
Montana indicated the average level of fluoride in leading pet foods to
be 11 to 193 ppm, with canned food having the highest amount. The
Montana researchers discovered that fluoride accumulates in pets’ bones.
84 to 1,535 milligrams of fluoride was found in the leg bones of dogs.
74 to 1,190 milligrams was found in cat bones, and it increased with
age. A number of lower-grade dog foods may contain up to 2,000 ppm of
fluoride. The government daily limit said to be safe for children over 3
years of age is 2.5 milligrams. Tolerance levels have been identified
for domesticated animals, with the lowest values for dairy cattle at 30
mg/kg feed or 2.5 mg/liter drinking water.

Numerous research has been done on sheep, pigs, goats, cattle and
chickens on adverse health effects from fluoride, with little
information relating to cats and dogs. “Consequently, it is safe to
assume that many of dogs and cats who appear to be suffering with
arthritis, dysplasia, spinal deformities, etc., may have actually
developed skeletal fluorosis.” Even though a particular breed may be
genetically predisposed to such health problems, fluoride in pet food
could prematurely trigger the disease.

“The primary source of the fluoride in pet foods is from the added
mineral supplements: defluorinated phosphate rock, raw soft phosphate
rock, mono and tricalcium phosphate. The less expensive the dog food,
probably the higher the fluoride levels because they use raw phosphate.

Raw phosphate, mainly because of its fluoride content (3 to 4 percent),
is the most physically damaging animal mineral supplement because it is
not processed and is the least-expensive. These facts have been known
since the 1920s in early animal nutritional research of fluorine in
animal nutrition.

Yeah, cancer is real funny.

Biological and physical evidence have led health officials to determine
a link between fluoride and bone cancer . Fluoride, once thought to have
health benefits, shows evidence of severe, long-term bodily health
effects. The link is most evident in cases of osteosarcoma cancer in
children who have been exposed to elevated amounts of fluoride during
childhood.

Fluoride and bone cancer have been inextricably linked due to biological
factors regarding fluoride build-up in bones. Fluoride accumulates in
the bones and can cause cancerous growths during the developmental
phase. While osteosarcoma can occur in both boys and girls, osteosarcoma
as a result of fluoride exposure is much more prevalent in young boys.

http://www.fluoridealert.org/health/...eosarcoma.html
As acknowledged by the U.S. National Toxicology Program there is a
"biological plausibility" of a link between fluoride exposure and
osteosarcoma. The biological plausibility centers around three facts: 1)
Bone is the principal site of fluoride accumulation, particularly during
the growth spurts of childhood; 2) Fluoride is a mutagen when present at
sufficient concentrations, and 3) Fluoride can artificially stimulate
the proliferation of bone cells (osteoblasts).

In addition to its biological plausibility, there is now a substantive
body of evidence indicating that fluoride can in fact induce
osteosarcomas in both animals and humans.

Most notably, a recent national case control study conducted by
scientists at Harvard University found a significant relationship
between fluoride exposure and osteosarcoma among boys, particularly if
exposed to fluoridated water between the ages of 6 and 8 (the
mid-childhood growth spurt).

The Harvard study's findings are consistent with the U.S. National
Toxicology Program's congressionally-mandated fluoride/cancer study in
rats; the National Cancer Institute's 1990 analysis of osteosarcoma
rates among young males in fluoridated versus unfluoridated areas in the
U.S., and the New Jersey Department of Health's 1992 analysis of
osteosarcoma rates among young males in fluoridated versus unfluoridated
areas of Central New Jersey.

In addition, two later independent analyses of NCI's national cancer
data also found a relationship between fluoridation and osteosarcoma
among young males (Yiamouyiannis 1993; Takahashi 2001).

Taken together as a whole, the evidence - laboratory, animal, and human
- suggests that fluoride could either directly initiate, or contribute
to, the development of osteosarcoma in boys under the age of 20.

This link is the most disturbing because it shows that the US Congress
asked for studies on this way back in 1997. A lot of people and pets
have died from this since then!

Do you really believe all that crap just because someone posted it on the
internet? You do realize I could make a real name seeming site on the same
theme and say feed your dog green beans and it's excellent for them?

Excite a grey cell by letting it exercise for a moment next time you read
one of those sites.
