Independently Proven Broad Spectrum Efficacy for Farm Disinfection

Big investments have been made in performance and safety testing, Virkon® S has a significant number of studies supporting approved label claims against the OIE List A Diseases, including, exotic Newcastle Disease, Highly Pathogenic Avian Influenza (Fowl Plague) and FMD.

Stringent EN 1656 studies confirm that Virkon® S is highly active against the five most prevalent human health-related Salmonella strains: S. enteritidis, S. typhimurium, S. virchow, S. infantis and S. hadar.

Virkon® S Beats the Challenges of Cold Temperature, High Organic Challenge and Resistance
The broad spectrum efficacy of Virkon® S for farm disinfection has been independently proven against over 100 strains of virus, 22 viral families, 400 strains of bacteria and 60 strains of fungi, using a wide range of contact times, temperatures and organic challenge levels. Likewise, the excellence of this Virkon®  S laboratory data is supported by superior on farm efficacy ensuring that low temperatures and high levels of organic challenge do not present a problem.

Additionally, leading veterinary laboratories have shown that Virkon® S is not associated with the development of resistance. [Ref. 2] The researchers concluded that the continued use of an oxidising disinfectant such as Virkon® S reduces the potential infectivity of Salmonella super-strains.


Virkon® S is Formulated for Speed of Kill
Formulated to overcome the problems of limited spectrum and limited activity exhibited by other disinfectants, Virkon® S achieves deactivation and destruction of the target organism through a broad-spectrum, non-selective range of oxidation reactions. Unlike other disinfectant chemistries, Virkon® S does not exert a specific toxicological effect on the target organism and is proven to kill pathogens in seconds.

Independent field trials have demonstrated the impracticality of many types of disinfectants for foot dips due to slow pathogen kill rates. When researchers at Indiana’s Purdue University in the U.S. compared the performance of six classes of disinfectants, [Ref. 3] namely aldehyde, chlorhexidine, chlorine-releasing agent, iodine-releasing agent, synthetic phenol and a quaternary ammonium compound (QAC), only the QAC disinfectant provided adequate foot dip disinfection. However, the QAC required an impractical five-minute soak after boot cleaning.

When the same researchers repeated the evaluation using Virkon® S, effective disinfection was achieved after boot cleaning in just 30 seconds.[Ref. 4] This independent study confirmed Virkon® S as the fastest and most effective disinfectant available for farm disinfection protocols as compared to other classes of disinfectant. This potent combination of efficacy and speed means that Virkon® S arms farmers with the best means of infection control, at low temperatures and in the presence of organic challenge.
