Operational Benefits

Independent studies conducted to European disinfectant test standards (EN 1276, EN 1656) have shown that Virkon™ H2O is effective against key poultry pathogens of concern at a 1:800-1:1500 dilution rate. These include the food poisoning pathogens Escherichia coli, Salmonella enteritidis and Campylobacter jejuni.



In times of flock stress such as; post vaccination, medical or micronutrient application periods, or after the ‘flock thinning’ process, Virkon™ H2O can be applied to the drinking waterline for a period of between 2-3 days to help ensure the highest level of biosecurity is maintained, promoting good flock performance. Virkon™ H2O has been formulated with enhanced solubility, to aid with easy preparation.



After periods of medication or feed additives to the waterline, there is an increased risk of biofilm build-up within the water system itself. Dosing Virkon™ H2O post treatment can help reduce any biofilm build-up within the drinking water system by controlling the planktonic bacteria that can initiate and increase biofilms. At the terminal disinfection stage, use Virkon™ H2O at a 1:100(1%) dilution rate to kill and remove biofilm build-up within the drinking waterline system. Fill the waterlines with disinfectant solution, leave for a minimum of 4 hours, then drain the system and flush through with clean fresh water.



Due to its unique and powerful oxidising formulation, Virkon™ H2O, at a 1:800-1:1500 dilution rate, has been shown to help inactivate some antibiotics in poultry drinking waterlines. This application can therefore help assist in the deactivation of antibiotic residues, after their withdrawal, and prior to the birds going to slaughter.


Virkon™ H2O can be dosed into the drinking water system up until the end of a flock cycle to disinfect and acidify the water during the antibiotic exclusion period, when there is a greater risk of pathogen challenge to the flock. Field trials and independent analysis have confirmed that there is no need for a Virkon™ H2O withdrawal period, with no residues of concern present in the birds at time of slaughter.



Virkon™ H2O powder concentrate is not corrosive to skin and does not cause sensitisation via the dermal and inhalation routes of exposure. A typical in-use dilution of 1:800-1:1500 is non-irritating to skin and eyes and is not a sensitising agent.



The ability of a disinfectant to work well at low temperature, especially in water, contributes to the value of its use on a daily basis. Temperature is a major factor for consideration, when selecting the best products for farm applications. Virkon™ H2O has been shown to be effective at 4°C ensuring biocidal activity is retained under lower temperature conditions.


The Virkon™ H2O oxygen-based chemistry contains simple inorganic salts and organic acids and the active ingredient decomposes by a variety of routes within the environment, in soil and water, breaking down to form the naturally occurring substances, potassium salts and oxygen. The major organic components are classified as readily biodegradable according to OECD and EU tests.


Virkon™ H2O is not classified as H413* and is not persistent in the environment, according to the standard European process for the classification and labelling of chemical preparations.



Governments worldwide are seeking reductions in the use of medicinal livestock antibiotics to limit the development of antibiotic resistance passing into the human population.  Targeted legislation to reduce the use of prophylactic antibiotics in the food chain is now becoming a reality within the EU, with the result that producers are taking steps to improve their biosecurity measures.With proven efficacy against food poisoning disease-causing organisms, Virkon™ H2O meets the toughest poultry drinking water biosecurity challenges and leads the way in biosecurity ‘best practice’ programmes.
