Inactivation of vegetative bacterial threat agents on environmental surfaces

► Inactivation of non-sporulating bacterial threat agents on complex surfaces is challenging. ► None of the decontaminants tested were able to completely decontaminate all biological agents on all surfaces. ► Resistance to chemical inactivation differed among the organisms tested only when a weak disinfectant was used. ► These results are intended to help guide decontaminant selection following a biological contamination incident.
