Abstract: The aim of this study was to develop a dynamic risk warning method of veterinary drug residues in raw milk because of dynamic changes of raw milk. Risk warning methods of veterinary drug concentration above MRLs, abnormal detection rates and average-standard deviation were developed based on theory of Shewhart control chart. Veterinary drug residues data of 1000 milk samples collected from a large dairy company were analyzed with Shewhart control charts and no risk warning were found. Abnormality of detection rate and average were assumed and also analyzed in this study.

Key words: raw milk; Shewhart control chart; veterinary drug residues; risk warning
