Establishment of scientific disinfection measures in domestic poultry farms and live-poultry markets (LPMs) are critical to prevent the spread of H7N9 subtype avian influenza that outbreaks in poultry and infection in humans. The current study was aimed to evaluate the efficacy of four common disinfectants to inactivate H7N9 subtype avian influenza virus (AIV).
According to the disinfection technical specification, the average inactivation logarithmic values of four disinfectants against the epidemic H7N9 subtype AIV, including deciquam solution, glutaral and benzalkonium bromide solution, sodium dichloroisocyanurate powder, and peroxyacetic acid solution, were systematically evaluated.
Our data showed that incubation of 0.005% (w/v) deciquam solution for 30 min contact time, or 0.05% (v/v) glutaral and benzalkonium bromide solution for 10 min, or 0.24 g/L sodium dichloroisocyanurate powder for 30 min, or 0.05% (v/v) peroxyacetic acid solution for 10 min, can completely inactivate H7N9 subtype AIV. These results suggested that glutaral and benzalkonium bromide solution as well as peroxyacetic acid solution at recommended concentrations can be effectively used to cut off the spread of H7N9 subtype AIV in poultry farms and LPMs, however, deciquam solution and sodium dichloroisocyanurate powder need to increase their working concentration.
