The supplemental NADA provides for the establishment of a tolerance for residues of laidlomycin in cattle livers. FDA is also taking this opportunity to codify the previously established ADI for total residues of laidlomycin. The supplemental NADA is approved as of May 12, 2003, and parts 556 and 558 (21 CFR parts 556 and 558) are amended by adding new § 556.346 and by revising § 558.305. The basis of approval is discussed in the freedom of information summary.
