Electrochemical disinfection: An efficient treatment to inactivate Escherichia coli O157:H7 in process wash water containing organic matter

► Electrochemical disinfection was tested in process wash water from the fresh-cut lettuce. ► Escherichia coli O157:H7 has been used as a model, due to its relevance in the fresh-cut products. ► Electrochemical treatment with BDD electrodes eliminated pathogens and COD of process wash water. ► This technology is suitable for the fresh-cut industry to maintain quality of wash water.
