This article discusses the removal of bacterial endotoxins in a washing process and the need for a
continuous monitoring activity according to common cleaning validation practices. Results of washing
tests performed with different load materials following an effective cleaning strategy to remove
microbiological soil are presented. In addition, this paper compares two different online assay methods:
conductivity analysis and Total Organic Carbon analysis.
