Admonitions against eating food with mercury
Emerging
Scandal in Vaccine Mandates
In
another announcement the same day, PHS-AAP issued a joint statement that
revealed the risk to children of vaccines containing mercury and called on the
FDA to "assess the risk of all mercury-containing food and drugs." A
mercury product called thimerosal is used as a preservative in many vaccines,
even though the FDA last year banned its use in over-the-counter products for
safety reasons.
Under
the current CDC schedule, most infants receive a total of 15 doses of
mercury-containing vaccines by the time they are six months old, many given
simultaneously. The fact that the FDA has prohibited the use of thimerosal for
most products, but continues to allow its use for vaccines, sounds like
political corruption in the vaccine approval process.
FDA issues pregnancy warning: Mercury in some fish could harm fetal brains, agency says
Pregnant women and those who might become pregnant should not eat four types of fish — shark, swordfish, king mackerel and tilefish — because they could contain enough mercury to damage a fetal brain, the government warned Friday.
Nursing mothers and young children should avoid those fish as well, the Food and Drug Administration said.
But what level of mercury the FDA deems safe is under attack. A major scientific report last summer said the agency should follow Environmental Protection Agency safety standards that are four times stricter — a standard that critics contend do make tuna a concern. The FDA is considering whether to change its standard.
San Francisco Bay seafood warning
"Mercury in breaking thermometers is the largest single household source of mercury pollution in the municipal solid waste," said Supervisor Mark Leno, who introduced the bill. The rivers that lead to the San Francisco Bay already supply more than 450,000 grams every year of poisonous mercury, enough to trigger a health warning against eating more than two Bay fish meals a month.
Report:
Fish-mercury risk underestimated
A report issued
Thursday says millions of pregnant women and their fetuses are at risk of
serious health problems from exposure to mercury in fish.
The report, prepared
by the Environmental Working Group and the U.S. Public Interest Research Group,
calls on the Food and Drug Administration to upgrade and strengthen its current
mercury safeguards.
The
FDA in January recommended that shark, swordfish, king mackerel and tilefish not
be eaten by pregnant women and women of childbearing age who might become
pregnant. It also recommended that nursing mothers and young children steer
clear of these fish.
But
the new report, "Brain Food: What Women Should Know About Mercury
Contamination in Fish," contends the recommendations do not go far enough
to protect women and children from mercury contamination.
FDA Warning: Harmful Mercury Levels in Some Ocean Fish a Danger to Babies: Advises Certain Women, Young Children to Steer Clear of Risky Fish
Pregnant women should avoid eating certain species of large ocean fish, the FDA announced today, because of a danger of contamination by methyl mercury, a substance that can harm the nervous system in a developing baby. The government warning applies to young children, nursing mothers, and women who might become pregnant, officials say.
The fish to be avoided are shark, swordfish, king mackerel, and tilefish. These fish live relatively long lives and eat lots of smaller fish that have been contaminated from both natural sources and by industrial pollution, says the FDA. That allows the mercury to reach high concentrations in the bigger fish, a process called "biomagnification."
"If officials are finding methyl mercury in these types of fish, pregnant women should not be eating them," says Jennifer Niebyl, MD, professor and head of obstetrics and gynecology at the University of Iowa.
"There are good data showing that high levels can be a problem," she tells WebMD, and recounts a famous 1959 epidemic of methyl mercury poisoning in Minamata, Japan. It caused neurological diseases, seizures, and other serious health problems.
The FDA does not recommend avoiding all fish, as there are many nutritional benefits of fish consumption.
Balancing
Risks and Benefits: Primum non nocere Is Too Simplistic
Based
on the NRC report, on January 12, 2001, the Food and Drug Administration (FDA)
recommended that pregnant women, women of childbearing age, infants, and very
young children not consume swordfish, shark,
tilefish, and mackerel because of unacceptably high levels of methylmercury.10
Swordfish contains an average of 1 part per million of methylmercury, or 28 µg/oz.
If a meal is 3 oz, a 55- to 70-kg woman should not consume 84 µg of
methylmercury at any point during pregnancy.
