Since 2001, the manufacturing rules put in place, via a quality manual and strict procedures, have been based on the HACCP standard.

Afin d’augmenter encore ses standards, la société Silly est certifiée FSSC 22000 (norme de certification du système de management de la sécurité des denrées alimentaires) depuis l’année 2021.

Silly has also decided to commit to a more sustainable vision from a societal, environmental and economic point of view, and has therefore embarked on a process to achieve Rainforest Alliance certified hazelnut certification. The first certification took place at the end of 2021.
