      Sporicidal products are of considerable importance in healthcare environments due to the
      requirement for products that are capable of dealing with contamination with Clostridium
      difficile spores. Sporicidal testing standards to validate the claims of sporicidal activity are an
      important tool in the evaluation of commercial sporicides. Within Europe there are a number of
      sporicidal testing standards which are often used to validate the claims of commercial sporicides.
      However, the extent to which these standards reflect the practical application of sporicides in
      healthcare settings is limited since they employ long contact times (�30 min) and do not involve
      surface contamination. Alternative international standards are available which employ
      contaminated carriers rather than spore suspensions, and the Organisation for Economic Cooperation
      and Development is currently developing a unified set of standards which are more
      realistic in their design than the currently available European standards. This paper reviews the
      currently available testing standards for sporicides, highlighting the key procedural differences
      between them and the extent to which they reflect the practical application of sporicidal
      products. Some of the common problems and errors associated with the application of the
      European sporicidal standard methods are also highlighted and discussed. Finally gaps in the
      currently available testing standards are identified and discussed.
