Abstract:
Five years after the initial recalls of various food products exceeding ethylene oxide (ETO) limits in the European Union, alerts keep being regularly issued, highlighting the continuous need for monitoring food items imported in Europe. However, the reliability of ETO measurement remains often questionable, mainly due to its high reactivity and volatility, ultimately complicating residue interpretation. This study summarizes the existing chemical and biochemical evidence on ETO and its major metabolite, 2-chloroethanol, while pointing out the regulatory ambiguities and challenges associated with reliable measurement and analytical method standardization.
