Detection and enumeration of E. coli typically rely on culture-based reference methods or the most probable number approach, which require 1–2 days to produce results—potentially delaying timely action during contamination events. In contrast, molecular techniques can deliver results within hours. The DWD permits the use of alternative methods if they are as reliable as the reference method and developing and validating such methods requires multiple laboratory trials in line with ISO standard 16140-2. Following this, we conducted a representative EU study to validate a molecular method based on real-time reverse transcription polymerase chain reaction for rapid E. coli detection in drinking water. In a concerted action, the first of its kind for drinking water, nineteen laboratories across ten Member States participated. To ensure consistency, drinking water was artificially contaminated with E. coli. The alternative method showed slightly lower sensitivity than the reference method (91.1 % vs. 97.2 %) but delivered much faster results, making it a valuable screening tool. It can support rapid decision-making during contamination events, reducing the risk of waterborne outbreaks and protecting public health. For reliable routine performance, appropriate training in this alternative method is strongly recommended.
