The certification for effectiveness against a number of bird viruses - paramyxovirus, Newcastle disease and avian flu - was previously awarded by the UK government authority MAFF (now DEFRA) to Citrox Limited.

Recently, scientists at Citrox recognised that further exhaustive up-to-date tests were necessary to cover any mutations which could have occurred since the original certification. This testing was carried out at one of the few approved, independent British laboratories, and the formulation, according to them, was found to be "eminently suitable for disinfection and decontamination".

CitroxxTM products have been tested independently by several firms and found to be effective (ie killing up to 99.998%) against :-
