In May 2025, the European Food Safety Authority (EFSA) published an updated risk assessment on perchlorate in food [EFSA Journal. 2025;23:e9393.]. Therein, EFSA derives a new tolerable daily intake (TDI) of 1.4 µg/kg body weight (bw)/day for perchlorate. The new TDI is clearly higher than the TDI of 0.3 µg/kg bw derived in 2014. As the TDI is applicable for both short-term (approximately 2-week period) and chronic exposures, according to EFSA an acute reference dose (ARfD) for perchlorate was still deemed not necessary.
