The use of synthetic hormones has been linked to the onset of early puberty along with a link to an increase in breast cancer cells in pubescent girls that lead to higher incidents of breast cancer masticizing.
This paper will not only review the history of how synthetic hormones are required to be used in a safe manner according to FDA regulations, but also in discussing the US/EU debate issue in how this issue relays to the general public using bipartisan discussion.
Since the European Union's ban on products containing beef hormones is not supported by scientific evidence, is detrimental to the United States cattle industry, and is detrimental to the over all economy of the United States, the United States is right in seeking an end to the ban.
According to the USDA government website, this is an ongoing issue over the past fifteen years between the US and the EU (European Union). The disagreement itself is over the use of hormones in cattle came to a head in 1989 when the EU effectively banned any U.S. exports of beef to their country that have been treated with growth promotants. The U.S. has retaliated with scientific studies, evaluations (EU and CODEX conducted) have supported the U.S. position.
The disagreement may have some merit with respect to independent testing of the effects that the synthetic hormones on a particular demographic community, mainly the increase in the onset of puberty in prepubescent girls along with an increase in the instances of breast cancer in females. The beef hormone issue is not specifically segregated to an increase in molecular alteration of cancer cells as described above, but, the increase in consumer awareness of the beef farmers using synthetic hormones with their cattle and the need to have labeling included stating the use of synthetic hormones.
The hormones that are naturally occurring in every human are required for normal physiological functioning and maturation and three of these hormones in question, estradiol, progesterone and testosterone, are naturally occurring in all humans and food animals. The other three hormones, trenbolone acetate, zeranol and melengestrol acetate (MGA), have been made into a synthetic version in order to mimic the natural occurring hormone versions.1
The FDA has conducted thorough research on the effects of growth hormones used on beef cattle since 1950 and had concluded there was no danger posed to human health and they concluded that there is "essentially no difference between beef from animals raised using hormones and those raised without their use."
There is a world wide consensus is that these hormones when used according to approved veterinary practices are very safe and the USDA web site advises that
this consensus is reflected in the 1984 and 1987 Lamming Committee reports-- the scientific expert group commissioned by the European Community; the 1987 Joint Expert Committee on Food Additives (JECFA) of the World Health Organization and the Food and Agriculture Organization of the United Nations; the Codex Committee on Residues of Veterinary Drugs in Food (CC/RVDF), the Codex
