On 6 May 2021, the European Food Safety Authority (“EFSA”) published its updated safety assessment on titanium dioxide as a food additive (E171). EFSA examined new evidence on nanoparticles and found that there was uncertainty about E171’s ability to accumulate in the body and damage genetic material in cells; i.e. genotoxicity. The agency could not calculate an Acceptable Daily Intake (“ADI”), nor could it determine a safe cut-off value for particle size and distribution. On that basis, it could not confirm the safety of E171 in food. However, since it found no evidence of acute toxicity, an immediate ban is not warranted. France previously initiated a national ban in 2019/2020; following EFSA’s revised opinion, the EU is likely to adopt an EU-wide ban early 2022. In this blog, we briefly review the planned EU-level response and the developments in the Netherlands, Germany and the UK.
