Hormones in U.S. Beef

U.S beef is heavily contaminated with natural or synthetic sex hormones. 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. These hormones increase carcass weight, adding over $80 extra profit per animal.

Also, and not surprisingly, but contrary to longstanding claims by the FDA and 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.
