Operational Benefits of Virkon™ H2O

Excellent control of food poisoning pathogens to EU test standards

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

Protects against infection, during stress and antibiotic withdrawal periods

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 water line for a period of between 2-3 days to help ensure the highest level of biosecurity is maintained, promoting good flock performance. 

Deters biofilm proliferation

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 at a 1:800 dilution rate can help deter the proliferation of biofilms within the drinking water system by controlling the planktonic bacteria that can initiate and increase biofilms.


Inactivates antibiotics in the drinking water line

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

Promotes good flock performance

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.


Good operator safety

Virkon™ H2O 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 is non-irritating to skin and eyes and is not a sensitising agent.

Proven activity at low temperatures

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.



Environmental profile

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.

Supporting the reduction of antibiotics

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 with the result that producers are taking steps to improve their biosecurity measures.

With proven efficacy against food poisoning disease-causing pathogens, Virkon™ H2O meets the toughest poultry drinking water biosecurity challenges and leads the way in biosecurity ‘best practice’ programmes.

NB. Virkon™ H2O is a biocidal product formulation, and is not classified as a licenced antibiotic material within the EU. Do not apply Virkon™ H2O for 12 hours prior to, or 24 to 48 hours after veterinary medicine or nutritional applications to the waterline.
