Microplastics are present in all beverages, but those packaged in glass bottles contain more microplastic particles than those in plastic bottles, cartons or cans. This was the surprising finding of a study conducted by the Boulogne-sur-Mer unit of the ANSES Laboratory for Food Safety. The scientists hypothesised that these plastic particles could come from the paint used on bottle caps. Water and wine are less affected than other beverages. These findings have highlighted a source of microplastics in drinks that manufacturers can easily take measures to address.
