INDEPENDENTLY PROVEN BROAD SPECTRUM EFFICACY

 

As part of our commitment to evolving chemistry, safety, and stewardship, we continually invest in performance and safety testing. And, Virkon™ S has a significant number of studies supporting approved label claims against the OIE listed diseases, including African Swine Fever, Foot and Mouth Disease (FMD), exotic Newcastle disease and highly pathogenic Avian Influenza (fowl plague).

 

For Salmonella, studies confirm that Virkon™ S is highly active against the most prevalent strains responsible for food poisoning.

 

The broad spectrum efficacy of Virkon™ S has been independently proven against:

 

  • Over 100 strains of viruses in 22 viral families
  • Over 400 strains of bacteria
  • Over 60 strains of fungi and yeasts

These studies were conducted using a wide range of contact times, temperatures, and organic challenge levels.

 

Formulated to overcome the problems of limited spectrum and limited activity exhibited by other disinfectants, Virkon™ S achieves deactivation and/or destruction of the target organism through a broad spectrum, non-selective range of oxidation reactions. For example, this may include oxidation of sulphydryl (-SH) and disulphide (S-S) groups and double bonds, causing damage to surface membranes leading to loss of cell integrity, as well as damage to lipids and proteins. 

 

Unlike other disinfectant chemistries, such as aldehydes, Virkon™ S does not exert a specific toxicological effect on the target organism and is proven to kill pathogens in just seconds.

 

PERFORMS IN THE LABORATORY. PERFORMS ON THE FARM

 

Virkon™ S demonstrates proven on-farm efficacy, offering farmers and producers reassurance and the knowledge that the disinfectant they are using will be effective in real farm conditions, where low temperatures and high levels of organic challenge can present serious problems to other biocides.

 

With stringent rules and regulations on Salmonella and Campylobacter control in place within the global poultry and swine production industries, Virkon™ S has proven efficacy, to EN test protocols, against these disease-causing organisms of concern. Tests were undertaken at the Wageningen University in the Netherlands, with the EN 1656 Salmonella and Campylobacter studies confirming that Virkon™ S has excellent dilution rates of 1:100 and 1:200 against the most prevalent Salmonella strains responsible for food poisoning; these include S. enteritidis, S. typhimurium, S. virchow, S. infantis, and S. hadar, Campylobacter jejuni and Staphylococcus aureus (animal origin MRSA).

 

Independent field trials have demonstrated the impracticality of many types of disinfectants for boot dips due to slow kill rates.

 

Researchers at Indiana’s Purdue University in the US compared the performance of disinfectants from six leading classes, 2 and only the QAC disinfectant provided adequate foot dip disinfection but required an impractical five-minute soak after boot cleaning.

 

However, when Virkon™ S was evaluated under similar circumstances, effective disinfection was achieved after boot cleaning in just 30 seconds.3  The study confirmed that Virkon™ S achieves excellent speed of kill at low temperatures and in the presence of organic challenge.
