Abstract

Five types of  traditional Nepalese  pots were tested  for  their bactericidal action against E. coli.. Copper, silver and brass pots were found to be very effective for their bactericidal action. Steel and aluminium  pots were found to be less effective whereas earthen pot was found to be ineffective against E. coli. Copper. silver and brass pots decreased the original bacterial load from 1010 cells/mL to  104 cells/mL within 4 hours. After 8 hours the bacterial load were found to be nil in those three pots. Whereas, in steel and aluminium pots, the bacterial counts were found to be decreased from  1010 to 109 cells/mL at the end of 24 hours. No change in bacterial load was found in earthern pot within 24 hours storage
