Hormones And Meat: does Beef Under-Regulation Generate Estrogenic Residues? (HAMBURGER) Project

The Hormones and Meat: does Beef Under-Regulation Generate Estrogenic Residues? (HAMBURGER) is a preliminary investigation into the potential impact of hormone residues in beef on breast cancer risk.

Treatment of cattle with synthetic or naturally-occurring sex steroid hormones is an established practice in the United States. Hormones speed development of muscle mass, thus helping to bring cattle to market more quickly and making beef production more cost-efficient.

There is very little information about residues of hormones in beef, and the few studies that are available are now outdated, relied on insensitive lab methods, were done in other places, or represent a small number of samples
