directed the Environmental Protection Agency to contract with the National
Research Council to prepare recommendations on the appropriate dose for mercury
exposure. That report was released
on July 11.
While the FDA relies on the Agency for Toxic Substances and Disease
Registrys dosing level for mercury of 0.5 micrograms per kilogram of body
weight per day is significantly higher than the EPAs dose of 0.1 microgram
per kilogram of body weight. In
that report, it was confirmed that the EPAs reference dose is correct.
We will hear from Dr. Vascken Aposhian, University of Arizona at Tuscon,
one of the scientists who worked on this report. Ramona Trovato will testify on
behalf of the Environmental Protection Agency.
413 of the Food and Drug Administration Modernization Act of 1997
required the FDA to compile a list of drugs and foods that contain intentionally
introduced mercury compounds, and provide a quantitative and qualitative
analysis of the mercury compounds in this list.
The Act also requires the agency to compile the list and provide the
analysis within two years after the date of its enactment on November 21, 1997.

The FDA determined that mercury compounds used as active ingredients in
Over the Counter drug products were not found to be generally recognized as
safe. Additionally the FDA has
not approved any mercury containing compounds as food additives and does not

is it that mercury is not safe for food additives and Over the Counter drug
products, but it is safe in our vaccines and dental amalgams?
Mercury Coincidence or Cause and Effect?
June 1999, the Food and Drug Administration discovered that Infants who
receive thimerosal containing vaccine at several visits may be exposed to more
mercury than recommended by Federal guidelines for total mercury exposure. Thimerosal,
a preservative used in some vaccines to prevent contamination, is 49.6% mercury
by weight. Infants who are being vaccinated using multi-dose vials with
thimerosal can receive 62.5 micrograms
of mercury per visit. For an average sized child this represents an
exposure approximately 100 times the 0.1 micrograms per kilogram of daily
exposure considered safe by the Environmental Protection Agency. The

part of an ongoing review of biologic products in response to the Food and Drug
Administration (FDA) Modernization Act of 1997, the FDA has determined that
infants who receive thimerosal-containing vaccines at several visits may be
exposed to more mercury than recommended by federal guidelines for total mercury
linked to mercury vaccine
In America, researchers found some
infants who are being vaccinated using multidose vials with thiomersal can
receive 62.5 micrograms of mercury per visit. This is 100 times more than the
intake considered safe for the average six-month-old by the US Environmental
Protection Agency. In June 1999 the
FDA discovered that: Infants who receive thiomersal-containing vaccine at
several visits may have been exposed to more mercury than recommended by Federal
guidelines. The following month the European Agency for the Evaluation of
Medicinal Products (EMEA) issued a statement saying: Cumulative exposure to
ethylmercury [found in thiomersal] . . . could lead to a potential cause for
