Toxic Additives In Pet Food

To compensate for nutrient loss in the manufacturing
process,  some chemically isolated vitamins and
minerals are added  (with high tech names such as
Pyroxidine hydrochloride, calcium pantothinate, iron
carbonate, potassium chloride and manganous oxide.)

If you are feeding your pet commercial pet food,
 those with the follwing additives:

Propylene glycol – Normally this is used as a de-icing
fluid for airplanes. It is put into pet foods to
maintain moisture and texture. It is added to prevent
bacterial growth but also inhibits the growth of friendly
bacteria within the intestines.
Propylene glycol
decreases the amount of moisture in the
digestive tract leading to constipation and cancer

Ethoxyquin – This was originally designed as a rubber
stabilizer and herbicide but before its approval,
it was considered a poison. At the outset, it was to be
used as a grain preservative in feed for animals
not expected to live for more than two years before
they are slaughtered. It has been reported to
cause liver cancer in dogs and malformations or even
death in newborn puppies

BHT and BHA – These have been very poorly tested.
They have been reported to
cause liver damage,
metabolic stress, fetal abnormalities and serum
cholesterol increases.
Added to preserve already rancid
fats in the food. Fats in this form are very difficult to
digest and
can lead to a host of health problems
including diarrhea, gas, bad breath ,vomiting

Artificial Coloring – These don’t have to be labeled
with any more definition than that.
They are all
coal tar derivatives which have been implicated in
anything from cancer to birth defects

Sodium Nitrate – This converts in the body to
nitrosamines, which are
very carcinogenic.
They are added to retain the red colour to make the
meat look fresh.

Thimerosal is a mercury containing preservative used
in vaccines. Mercury is
a known neurotoxin. There is a
vast amount of research/discussions going on globally
at this point in time relating to mercury in dental
amalgams, vaccinations and the environment in

Many researchers are linking mercury to the
tremendous increase in autism in children.
If you do decide to immunize your animal,  
insist on
thimerosal-free vaccinations
. They do exist..but they
do not have the same shelf life.

Heavy Metal Toxicity – Because meat is high on the
food chain, contamination with heavy metals
such as lead and mercury is very much a concern. Spot
checks on cat food have revealed lead levels ranging
from .9 ppm to 7.0 ppm and dog food anywhere from
1.0 to 5.6 ppm.  It
should never be over .5ppm.
