Does the U.S. Food and Drug Administration (FDA) have regulations on the residue limit of Tilmicosin? Can you provide the residue limit in ppb and the corresponding reference materials?

Question

Accepted Answer

The FDA has not set a clear residue limit (MRL) for Tilmicosin. However, according to European regulations and the Turkish Food Code, the maximum residue limit for Tilmicosin in beef is 75 μg/kg and the maximum residue limit in pork is 50 μg/kg.  (μg/kg = 1 ppb (part per billion) = 1 microgram of element per kilogram)
