The RD 1620/2007 which establishes the legal status of the reuse of purified water, includes the determination of intestinal nematodes eggs in most of the permitted uses by modified Bailinger's method. However this analysis is considered simple, its limitations are known and there is still a need for further evaluation, as well as a optimization in order to increase the recovery of eggs and, therefore. To optimize the method, eggs of Ascaris suum and Trichuris suis were coloured with crystalline violet. Samples were studied in parallel, comparing the official method and the modifications with best results. Thereby, the recovery is able to reach from 50% up to 70%. Source
