This study assessed the safety of commercially available Cordyceps militaris in Korea by analyzing seven heavy metals, 321 pesticide residues, and three radionuclides in ten domestic and imported samples. Cadmium was not detected in any sample, and all other heavy metals were detected at trace levels within safe limits. Two pesticide residues, metalaxyl and carbendazim, were detected in one sample imported from China, both below the MRLs established for other mushroom species in Korea. Radioactivity was not detected in any sample, although concentrations in samples from China tended to be higher than those in domestic samples. Overall, all contaminants were within safe limits; however, given the absence of Cordyceps militarisspecific regulatory standards in Korea, the establishment of crop-specific MRLs and systematic safety management throughout the cultivation-to-distribution chain are warranted.
