“This week, EFSA published a literature review of studies on microplastics and nanoplastics migrating from food contact materials (FCM). From the 1711 documents published between 2015 and January, 2025, 122 were selected for review. Most studies concern microplastics, “while data on nanoplastics were almost entirely absent”.

The results of the review by the European Union’s food safety experts were candidly frank and critical. Almost all studies detecting microplastic and nanoplastic exposure were deficient, unreliable and corrupted; they overstated their findings and had weak methodologies.

‘Many publications are affected by methodological shortcomings in test conditions, in sample preparation, and by deficiencies in the reliability of analytical data, with the consequence of frequent misidentification and miscounting. … In view of all this, there is no sufficient basis at this stage to estimate MNP exposure from FCM during their uses.’

This is diplomatic science-speak for concluding that most studies claiming microplastic and nanoplastic exposures were baseless.”
