Halamid® is not as aggressive as many other disinfectants which means it is easier to use and safe for equipment and environment. Most other oxidativedisinfectants have a high but short term activity. In a poultry house, a contact time of 30 minutes or longer, allows for a high dilution while still obtaining excellent hygiene scores. But in for example a foot bath, pathogens should be killed much faster. Therefore we have tested Halamid® at 5 minutes contact time against a number of relevant viruses (Vaccinia, BVDV, MNV) and at high soiling conditions. In all cases Halamid® passed the test at 1 % use solution (10 C). Halamid® has the unique ability to remain active over a long time, but when time is short it does still provide the necessary biosecurity.
