Hormones in U.S. Beef Linked to Increased Cancer Risk
CHICAGO, IL, October 21, 2009—/WORLD-WIRE/—Beef produced in the United States is heavily contaminated with natural or synthetic sex hormones, which are associated with an increased risk of reproductive and childhood cancers, warns Dr. Samuel S. Epstein, Chairman of the Cancer Prevention Coalition.
The hormones in past and current use include the natural estrogen, progesterone and testosterone, and the synthetic zeranol, trenbolone, and melengesterol.
When beef cattle enter feedlots, pellets of these hormones are implanted under the ear skin, a process that is repeated at the midpoint of their 100-day pre-slaughter fattening period, Dr. Epstein explains. These hormones increase carcass weight, adding over $80 in extra profit per animal.
Also, Dr. Epstein says, “Not surprisingly, but contrary to longstanding claims by the U.S. Food and Drug Administration (FDA) and the U.S. Department of Agriculture (USDA), residues of these hormones in meat are up to 20-fold higher than normal.”
“Still higher residues result from the not uncommon illegal practice of implantation directly into muscle. Furthermore, contrary to misleading assurances, meat is still not monitored for hormone residues,” Dr. Epstein emphasizes.
Nevertheless, he points out, the FDA and USDA maintain that hormone residues in meat are within “normal levels,” while waiving any requirements for residue testing.
Following a single ear implant in steers of Synovex-S, a combination of estrogen and progesterone, residues of these hormones in meat were found to be up to 20-fold higher than normal.
The amount of estradiol in two hamburgers eaten in one day by an 8-year-old boy could increase his total hormone levels by as much as 10%, particularly as young children have very low natural hormone levels.
Not surprisingly, Dr. Epstein says, the incidence of childhood cancer has increased by 38% since 1975.
...On January 1, 1989, the European Community placed a ban on meat imports from animals treated with growth inducing hormones. This had a direct impact on the U.S. beef industry, which uses hormones in more than half of the cattle sent to market each year.
