New FPF dossier: Microplastics

Food Packaging Forum (FPF) publishes background article and dossier informing about microplastics; discusses sources, analytical approaches, health hazards, and risk assessment


Microplastics are an invisible form of plastic pollution; effects on human health and the environment are largely unknown; summary article and FPF dossier define microplastics, explain sources and occurrence, focus on food contact materials


Microplastics have been found in all environmental compartments and in biota. Food is one source of human exposure to microplastics, and initial studies have shown that food packaging and processing equipment can contribute to this contamination. Risk assessment of microplastics that is based on exposure and toxicity data is currently hampered by insufficient data.

Review of ingestion of microplastics

Literature review estimates 20% of sampled aquatic organisms have microplastics in stomach and intestines, average of 4 microplastic particles per organism; call for urgent standardization of analytical methods
