Revisiting European diffusion: ISO 22000 Certification

Purpose – This paper aims to update and report the diffusion and forecasting model of ISO 22000 certification in Europe.

Design/methodology/approach – A research method similar to that described by Granja et al. (2021) was adopted. The results of the ISO 22000 evolution among European countries (ranging from 2007 to 2018) have been updated to consider available data regarding the years 2019 and 2020. The behavior of the number of ISO 22000 certification over the years was studied adopting the Gompertz model.

Findings – The results obtained by fitting the data to this model were dissected enabling a forecast for the forthcoming years. Similarly, encompassing the conclusions of the original study, the diffusion throughout the years of the number of ISO 22000 certificates also presents an S-shaped behavior. This present study also confirms similar behavior between ISO 14001 and ISO 22000 standard diffusion processes.

Research limitations/implications – Despite the new data added to the analysis, the results of ISO 22000 certification behavior in European countries data include uncertainties, and to overcome this lack of data, it is necessary to update it with new data from the forthcoming years.

Originality/value – This paper updates and confirms results presented by Granja et al. (2021) encompassing the first study of the ISO 22000 diffusion in Europe over the years.
