HPP dates back to the 1890s and is possibly the most mature and well accepted of these technologies. Commercial operations are increasing year-on-year as prices drop and applications broaden. When this is combined with a solid body of scientific evidence for a broad range of microbe-inactivation scenarios and consumer acceptance, you have an all-round winner.
Other techniques developed many years ago, like ozonation as a form of cold plasma technology, are finding diverse niches, for example in domestic use and for elimination of residueagriculturalchemicals like pesticides.
An approach, conceptually distinct from mechanical-based technologies is phage biocontrol, which has been commercially available for nearly 15 years. It was originally used by Georgia and Russia in a therapeutic context as an alternative to

antibiotics from the 1930s. Phage biocontrol technology started as an extremely effective, safe and sustainable biological control method to reduce or even eliminate Listeria monocyotgenes contamination on food surfaces.
What we do know, is that with the rapidly changing foodborne and infectious disease landscape, science and technology have the tools to combat nearly any food safety orfoodspoilageassault. ✷
