## Abstract

The Food and Drug Administration (FDA) is amending the animal drug regulations to reflect the correct assay limits for lasalocid in Type A medicated articles. Although a supplement to the new animal drug application (NADA) was approved, the regulations had not been previously amended to reflect that approval. At this time the regulations are amended to reflect the current assay limits in the approved NADA.
