Findings:
The study demonstrated the antimicrobial properties of cast copper alloys with regard to E. coli O157, and consequently these alloys have the potential to aid in food safety. For example, the survival of E. coli O157 in high-copper alloy C87300 was significantly reduced, with complete kill of 107 cells achieved after 75 min without beef extract and in 90 min even with the beef juice.
