Du Pont Virkon® S Proven to Control New Avian Influenza (H7N9) Threat

16 May 2014

EUROPE - Poultry farmers are being advised to stay on guard against the potentially lethal H7N9 avian influenza virus with the independently proven biosecurity disinfectant, Virkon S.

With wild birds starting to pose a threat to poultry flocks during migration, biosecurity experts of DuPont Disinfectants are offering poultry farmers advice on enhanced biosecurity measures to keep both themselves and their flocks free of this serious new threat.

Current data suggests that H7N9 is not easily spread from person-to-person but exposure to infected poultry or to the contaminated environment is thought to be the cause of the human infections.

However, the Centers for Disease Control and Prevention (CDC) are concerned that the H7N9 virus will mutate, enabling it to spread easily among people, triggering a global pandemic. The 2009 H1N1 pandemic occurred as a result of a mutation that created a new virus for which humans had little or no immunity. For this reason, it is important that virucidal and antimicrobial products must have proven efficacy against H7N9.

Mark Squire, Chief Chemist, DuPont Disinfectants explains: “As part of DuPont’s ongoing investment into the Virkon product range, Virkon S has been tested recently against the H7N9 avian influenza virus at a leading testing laboratory, ATS Labs in Minnesota, US.

"Regarded as one of the most potent virucidal disinfectant agents, Virkon S has proven efficacy against the H7N9 virus at a 1:600 dilution. Importantly, extensive investment to assess the safety of Virkon S shows that operatives have no need for excessive personal protection during biosecurity procedures.

"This makes Virkon S more suitable for use on smaller farms and homes where the poultry are often kept in close proximity to people.”
