EFSA’s Scientific Colloquium 25 “A coordinated approach to assess the human health risks of micro- and nanoplastics in food,” 6-7 May 2021

Thank you to all the speakers and participants in our #Microplastics21 scientific colloquium on the emerging area of risk assessment: microplastics and nano plastics in food. Videos of the plenary sessions will be added to this page in due course.

Microplastics are small particles of plastic less than 5mm in size; nanoplastics are even smaller, ranging from 1 to 100 nanometres (N.B. 1 nanometre equals one-millionth of a millimetre).

In 2016, EFSA identified the need to generate more data on their occurrence levels in food and on their potential effects on human health following exposure. Recently, international reports on microplastics and nanoplastics have been published, yet many of the food safety aspects remain unaddressed.

Public concern about this topic is high. EFSA’s 2019 Eurobarometer on Food Safety in the EU found that microplastics in food was a topic of increasing concern among EU citizens.

Therefore, EFSA is holding a scientific colloquium with the following objectives:

  • bringing stakeholders together,
  • understanding the current state of play and ongoing research on this topic
  • building possible synergies,

The colloquium will take place online on 6 and 7 May 2021.

Structure of the event

The draft programme will include presentations and discussion groups exploring questions on microplastics and nanoplastics in food and feed:

  • Developments in analytical methods for micro- and nanoplastics
  • Developments in exposure of humans to micro- and nanoplastics
  • Developments in hazard identification and characterisation for micro- and nanoplastics

E-posters and pitches session

We are holding hold an online e-poster and pitches session during the event. E-posters and pitches accepted are published on the event microsite. Authors of accepted posters and pitches will receive detailed technical guidelines on how to prepare and submit their e-poster and pitch.


Who should attend?

The meeting is intended for researchers, scientific assessors, policy-makers and others with a potential interest in this topic, e.g. NGOs, industry, journalists. Participation is limited to a maximum of 120 attendees. The final selection aims for a balanced representation of expertise and backgrounds.
