Much of the U.S. beef cattle are fed synthetic hormones in the feedlots prior to slaughter. The chemicals are essentially growth hormones meant to increase the net amount of meat produced from each cow, but numerous concerns have been raised (by the National Cancer Association, no less) about the high incidence of hormonal cancers produced as well. As early as 1989, the EEC (European Economic Community) put its collective foot down and said that’s not okay, and banned the treated beef from being sold in any E.U. country, though some of those restrictions have since relaxed depending on the hormones used. There have also been other issues like mad cow disease, leading to China also banning American beef products. Ironically, the U.S. has banned much of the Europe’s beef products, too, because of mad cow disease.
