The Wakayama poisoning case was that curry served at summer festival on July 25th, 1998, was poisoned by arsenic with a paper cup. It has not been widely known but desk-top type X-ray fluorescence analysis was performed for the forensic analysis, and Si and Ca was found to be related to the Ba detected arsenic. The present paper concludes that the desk-top X-ray fluorescence analysis was more informative than SPring-8 analysis.
