About Us

FreshCheck was founded in 2015 by John Simpson and Alex Bond – PhD alumni from Imperial College London. The initial research looked to use siderophores that are excreted from microbial cells, as markers of microbial contamination.

The 1st commercial product from FreshCheck was a colour-change hygiene verification spray that was evaluated by Campden BRI and found to be a unique solution for the testing of large surfaces. Field trials into test markets in 2019 resulted in limited production runs for specific customer markets and the feedback resulted in the integrated FreshCheck Hygiene Veficiation System consisting of:

  • FreshCheck Swab Device

  • FreshCheck App
