Disinfectants for avian influenza virus
For all your livestock needs
Following good bios- ecurity and hygiene prac- tices are essential to pro- tecting poultry and people from avian influenza.
Whichever product you choose to use must be used as directed by the manufacturer.

First, remove all visible organic matter such as faeces, urine, dirt, mud and such by washing the surface with water under pressure.

Wild birds can carry avian influenza without showing any signs.
Contact times will vary between chemicals and different surfaces, that is porous surfaces such as wood versus non-porous surfaces such as metal. Disinfectants for AI
Remember, chemicals may be toxic to poultry and other animals, even in very small doses.
When using a cleaning agent or detergent, follow the manufacturer’s in- structions – in particular the right concentration of cleaning produce for the amount of soiling and or- ganic matter present.
For advice on chemi- cals effective against AI virus and their safe use around poultry, contact your veteri- narian or the product manufacturer.

A quality solution for wastewater pumping

If they are looking for the best quality wastewa- ter pump, they will gener- ally look no further than a Gorman-Rupp self-prim- ing heavy-duty trash pump from Hydro Innovations.
• A wear plate that can be replaced without dis- connecting the pump from piping or driver
• A burst disc in the flap valve to vent excess pres- sure back to the wet well if the pump inadvertantly runs against a closed head – protecting operator and machine.
These pumps are rugged, reliable, can be mounted at surface level and often per- form unnoticed in plants for decades.
And it’s not only heavier construction that engineers look for.
• A self-cleaning wear plate that enables units to handle stringy materials such as rags, wipes and baling twine
• Double lip seals to protect pump bearings in case of a seal failure.

AVIAN influenza is a highly infectious dis- ease affecting many bird species including pet and farmed chick- ens and can result in significant deaths on poultry farms.
First, clean poul- try housing, boots and equipment thoroughly to remove any organic matter such as soil, mud and faeces, using water – preferably hot – and detergent.
detergent will strip the fatty envelope and kill the virus
Decontamination
It is wise to ensure that the disinfectant being used will not damage the product being cleaned and is not corrosive at the dilution rate being used.
Biosecurity practices should be focused on separating wild birds from domestic birds, and good hygiene measures taken as people move between different flocks.
Care should be taken to determine the safety of disinfectants prior to using them near poultry, and they should always be stored well away from poultry houses.
Where can I get more information?
Cleaning and disinfec- tion are important parts of biosecurity.
Avian influenza virus is a Category A lipid enveloped virus, and it is stable over a pH range of 5.0-8.2.
If using a footbath at the entrance of a poultry enclosure, place it out- side the enclosure and in an area where other animals including pets cannot access and drink from it.
Also, follow personal protective equipment recommendations of the manufacturer.
More information on AI and the Golden Plains situation is avail- able on the Agriculture Victoria website agri culture.vic.gov.au/biose curity/animal-diseases/ poultry-diseases/avian- influenza-bird-flu
To be effective against AI virus, the following two-step process is rec- ommended.
The following options will be effective in de- stroying AI virus on sur- faces:
Second, apply an ef- fective disinfectant as directed by the manu- facturer.

But when a pump is less than half the weight of the market leader and needs to run twice as fast to deliver the same performance, alarm bells should start ringing.
The following are pump features engineers may in- clude on their checklist:
• A suction flap valve that can be inspected or replaced without discon- necting suction piping
Eighteenth century phi- losopher John Ruskin said it best: “There is hardly anything in the world that some men cannot make a little worse and sell a lit- tle cheaper, and the people who consider price only are this man’s lawful prey.”
Ear tags, pieces of hoof and bits of baling twine are not going to be kind on these fast running, so- called, “semi-trash” pumps.
• An impeller that can pass a full 76mm solid
• Acid and alkaline chemicals
If vehicles, livestock trucks and trailers, ani- mal yards and equip- ment need to be decon- taminated, the following two-step cleaning and disinfection process should also be used.

“Avian influenza is pre- sent in our wild birds and environment, so it can oc- casionally spill into our
“It is crucial we identify these cases quickly, so we can stop it spreading.
“This includes controls on buying, selling or mov- ing eggs, manure and chickens, whether on the side of the road, from your property, your local store, online such as through Gumtree or Facebook or at markets.
“Report sick or dead birds anywhere in the state to the 24-hour Emer- gency Animal Disease Watch Hotline on 1800 675 888 to help eradicate avian influenza.”
A strain of highly path- ogenic avian influenza H7N7 virus was first de- tected at a free range egg farm near Lethbridge on July 31, with a second af- fected farm confirmed to have the virus on Thurs- day August 6.
“Purchases of eggs and chicken meat from retail food outlets and super- markets are not restrict- ed,” Dr Cooke said.
Turkey farms in the Golden Plains Shire and at Bairnsdale were found to have the low pathogen- ic strain H5N2 of avian influenza on August 10.
In addition, a housing or- der is in place for Golden Plains Shire requiring all bird owners – pet, back- yard and commercial – in the area to house or keep their birds in an enclosure for a minimum of 30 days from August 7.
“With no live birds re- maining on the infected properties, work is now underway to thoroughly decontaminate the sites to ensure we eliminate all remnants of the virus,” Dr Cooke said.
The Department of Health and Human Servic- eshasconfirmedtheH7N7 and H5N2 strains of avian influenza are not a risk to the public as they rarely affect humans unless there is direct and close contact withsickbirds.
Movement of domestic birds, bird products and equipment into, out of or within the Restricted and Control Areas spanning all of the Golden Plains Shire and the specified area near Bairnsdale, is not allowed without a permit from Agriculture Victoria.
There are no food safety issues identified – prop- erly cooked chicken meat and eggs are safe to eat.
