Under its Regulatory Fitness and Performance Programme (REFIT), the European Commission has been reviewing existing Union legislation in selected policy fields through ‘fitness checks'. Fitness checks aim to keep current legislation ‘fit for purpose’ by identifying excessive burdens, overlaps, gaps, inconsistencies or obsolete measures, which may have appeared over time since the Union legislation was first adopted and implemented. On 2 October 2013, the Commission decided to carry out a comprehensive evidence-based policy evaluation of Regulation (EC) No 178/2002 on General Food Law for the entire food and feed sector under the REFIT. The outcome has been Regulation (EU) 1381/2019, the so-called Transparency Regulation, which started to be implemented in March 2021.
