Didn't we have some discussion of possible hormone increases in beef due to implanting growth stimulants a while back?
Found an old clipping, unfortunately with no date or name of the paper it is from, but carries some information from the early days of Beef Checkoff work to end some of the myths harming beef consumption.
I happen to believe work such as this, from the research giving the proof to the dissemination of the accurate information to the public, ultimately has an effect even today on beef consumption.
***************
Myth: The use of antibiotics and hormone growth implants in livestock production is causing hazardous residues in beef and contributing to the development of health problems in humans.
Fact: No residues from feeding antibiotics are found in beef, and there is no valid scientific evidence that antibiotic use in cattle causes illness resulting from the development of antibiotic-resistant bacteria.
Authorities agree that use of hormone impts results in the efficnt production of beef that is safe.
Hormones are naturally present in infinitesimal amounts in all meat, whether from implanted animals or not. The amount of estrogen in plant-source foods iarger than in meat. The human body produces hormones in quantities much greater than would ever be consumed by eating beef or other foods. Hormones in beef from implanted steers have no physiological significance for humans whatsoever. The strogen level in a 3-oz. serving f beef from an implantesteer is 1.85 nanograms (a nanogram is a billionth of a gram): the level in the same size portion of beef from a non-implanted steer is 1.3 nanograms. By comparison, a non-pregnant woman produces 480,000 nanograms of estrogen daily.
Hormone implants also increase the efficiency of beef production, thus alleviating energy, feed usage and environmental impacts, and improve overall quality and healthfulness of beef by reducing the amount of fat.

I know this material is several years old, but believe the information is currently correct and of interest when considering this issue, but will accept correction from anyone with better or more current facts.
