Limitations of recent cellulose studies: How overzealous dispersion technique, fluorescence labeling and interpretation limit the findings of recent safety assessments for cellulose materials

Vireo strongly supports the responsible development of alternative testing methods including New Approach Methodologies, NAMS, for safety demonstration, and has collaborated in the past to advance their development and acceptance. But, on review, we found there are significant issues with the findings and conclusions of two reports on the safety of micro and nanofibrillated celluloses recently published as part of a European Food Safety Authority (EFSA) – funded Pilot Project on New Approach Methodologies for the Hazard Assessment of Nanofibers.  Our Short Communication in Trends in Food Science & Technology identifies several issues with the design and reporting of these studies, and raises concern that incorrect interpretations and conclusions were drawn.
