Each year, my Department implements a national residue plan for the purpose of detecting a range of illegal residues, including hormones. The laboratory methods used to test samples for the presence of hormones are capable of distinguishing between synthetic and natural hormones. Of 16,233 tests conducted in 1998 and 1999 specifically for hormones, 12, or 0.07%, were positive. Of these positives, five showed a presence of synthetic hormones while natural hormonal substances were indicated in the case of the remainder.
