Virus Control Begins on the Poultry Farm
Your guide to preventing the spread of Avian Influenza, Newcastle Disease Virus, Avian Reovirus, Avian Rotavirus, Human Corona
Virus (the viral type associated with SARS) and other deadly viruses. Presented by Dow Microbial Control, GLUTEX™ sanitizers and
antimicrobials made with GENUINE GLUTARALDEHYDE can help protect your farm against bacteria, viruses and fungi.
Virus Control Begins on the Poultry Farm
Your farm is under constant threat of disease from potentially fatal viruses such as Avian Influenza (H6N2/H5N1), Infectious Bursal
Disease Virus, Newcastle Disease Virus, Avian Reovirus, Avian Rotavirus, Human Corona Virus (the viral type associated with SARS),
Marek’s Disease Virus, Infectious Bronchitis Virus, Avian Laryngotracheitis and other pathogens.
These diseases can be spread from your poultry farm and in some cases into the human population through contaminated housing,
unsanitary equipment, other animals, farm staff or visitors, environmental stress, unclean feed, pests and parasites, contaminated
water, or other means.
This guide outlines a number of measures, also recommended by the World Health Organization1 and the US Department of
Agriculture2, that can help you eliminate and control poultry disease through a comprehensive sanitization and disinfection
program. Following this program can provide rapid protection for you, your family, your co-workers, your farm and the broader
human population.
For poultry farms we recommend disinfection steps in three areas: environment, people, feed & water equipment.
Environment
The best way to avoid disease spread into the environment is
to prevent the introduction of microorganisms onto the farm.
Implementation of strict sanitization practices and farm protocols
is the best way to keep potentially deadly diseases at bay.
Ideal prevention measures start with a perimeter link fence to
keep wild animals, rodents and other animal pests out of the
farm. Similarly, mesh screens over all windows will keep wild,
potentially disease-carrying birds out of poultry houses. Keep
all windows or ventilation openings clean and in good working
condition. Extractor fans need to be cleaned and disinfected at
least once per week and should therefore be easily-accessible.
Treat cooling-tower water and wet wall filters with disinfectant
to ensure that cooling and ventilation systems provide the
cleanest air possible.
All buildings should be as free of surface dirt as possible to
ensure that disinfection practices are not inhibited. A complete
disinfection of buildings entails spraying or fogging with
disinfectant to reach inaccessible parts of the structure. Remove
all moveable equipment and animals from rooms before
disinfecting. Since mops and natural-bristle brushes can harbor
germs, use squeegees and plastic-bristled brushes to clean
surfaces. Sanitize and hang cleaning tools to air dry before their
next use. After the disinfection process is complete, allow the
structure of the houses to dry completely to further help kill
microorganisms. Disinfect trash and other waste, and burn
dead animals to prevent cross-contamination.

The floors of egg-layer cages should be kept smooth and clean
to minimize the risk of egg contamination. Disinfect the egglayer pen twice per day and do not remove hens from their
cages. Adult hens must lie on dry surfaces to minimize the
growth of microorganisms.
Animal waste trays or belts below the adult hens should be
thoroughly sanitized daily. Thoroughly wash all eggs before
sorting and packing for sale and before sending fertile eggs to
the hatchery.
Special care needs to be taken in the hatchery to ensure
the cleanliness and health of the newborn chicks. Newlyhatched chicks should be moved to the farm the same day
they hatch. Regularly clean conveyor belts, tables, carousels,
and vaccinators with disinfectant wipes after each new chick
is vaccinated, and immediately collect and incinerate all
waste. Disinfect boxes both before and after moving chicks
from the hatchery to the farm. Be sure to disinfect hatching
facilities after new chicks are removed, and before new eggs
are introduced into the facility. Finally, before moving new
chicks to the broiler house, ensure that it has been thoroughly
disinfected. All farm vehicles and heavy equipment need to
follow the same strict cleaning and disinfecting regimen as
the farm facilities. Farm staff should control all traffic flow to
and from the farm. All delivery and visitor vehicles, as well as
the farm’s own vehicles, need to follow the farm’s cleanliness
policy. These practices stress the cleaning of tires with a
disinfectant before and after each vehicle enters the farm.
Cargo areas of each vehicle should also be disinfected after each
delivery is unloaded.
Virus Control Begins on the Poultry Farm
To prevent disease spread at the environment level, the following steps should be considered:
• Wherever possible, ensure that deliveries reach only the farm perimeter and that drivers do not enter critical areas. All vehicles
that do enter the farm need to be thoroughly cleaned and disinfected before entering the farm. Let disinfectant stand on the
vehicle for ten minutes before rinsing.
• Make sure all outside land is cleared of litter, food scraps, debris and animal waste.
• Remove all trees, tall grasses and large shrubs from the immediate perimeter surrounding poultry facilities.
• Establish a well-planned rodent baiting and trapping policy. Inspect the site after dark every two weeks to check for live rodents.
• Install mesh screens over openings in buildings to prevent the entry of birds and other pests.
• Clean and disinfect extraction fans at least once per week.
• Treat cooling-tower water and wet wall filters with disinfectant to ensure uncontaminated airflow.
• Thoroughly clean and disinfect trucks before and after animals are loaded.
• Power-wash entire buildings inside and out with disinfectant.
• Spray all moveable equipment in addition to walls, floors, posts and pens.
• Fog or mist all facilities with disinfectant as often as possible in all farm buildings to achieve very high levels of infection control.
• Clean hatchery facilities with disinfectant after new chicks are moved into the broiler house and before new eggs are introduced.
• Disinfect conveyor belts, tables and vaccinators after vaccinating each bird.
• Clean egg-laying cages twice per day with disinfectant.
• Remove animal waste trays and clean thoroughly.
• Disinfect trash and other waste and burn dead birds.

People
Hygiene is a critical factor in disease control and staff training is essential to ensure a successful disinfection and sanitization
program. The most effective step in preventing infection is restricting entry to the farm from anyone other than essential farm
workers or veterinary staff. Post written hygiene operating procedures or protocols in prominent places and ensure that everyone
who enters the farm follows them. Creation of separate entry points and exit points with hand and boot wash facilities can help
control access to the farm and further help prevent the spread of disease.
Before entering the farm area, staff and visitors should shower using an antimicrobial soap. Farm managers should provide staff
and visitors with the appropriate protective clothing to wear after showering, including waterproof boots and protective overalls.
This gear should only be used on the site and needs to be disinfected regularly on the farm premises in washing units designed
specifically for this purpose. Where on-site disinfection is not possible, specialist contracted laundry services should be used.
When entering and leaving a poultry unit or outdoor site, staff should immediately clean and disinfect boots and wash hands using
warm water and an antimicrobial hand soap. Farm management should provide paper towels for drying and ensure that a plastic
bag-lined trash bin is located near the sink to collect used towels. Once full, these bags should be disinfected and incinerated.
Most importantly, entry to hatcheries, egg-laying areas and egg-collection areas should be restricted to those with essential duties.
To ensure compliance by all staff and visitors, clearly identify the perimeter of each poultry unit and post signage that directs all
visitors to a specified entry point and instructs them to wait to be admitted by farm staff.
Virus Control Begins on the Poultry Farm
To prevent disease spread through staff and visitors, the following steps should be considered:
• Restrict access to live animal areas to essential workers only. The only visitors that should be allowed into
these areas are veterinary personnel and maintenance workers.
• All workers and visitors should wear protective clothing and rubber boots.
• Establish a personal hygiene/disease control protocol and train staff on its use. Post the written
protocol in prominent places throughout the farm and be sure all visitors and staff follow it.
• Prior to entry into animal facilities, all staff and visitors should shower and wash their hands well with an
antimicrobial hand soap.
• Create separate entry points and exit points to animal areas. Provide hand and boot washing facilities at
each point.
• Provide paper towels and a plastic-lined waste bin near every hand washing station. Disinfect and
incinerate full bags.
• Prior to handling animals or equipment, apply microbial barrier cream to hands and arms. After handling
equipment or animals, clean hands with a waterless hand cleaner. Install dispensers throughout animal
facility, and be sure antimicrobial soap is always available. Reapply microbial barrier cream frequently.
Workers and visitors may also use disposable disinfectant wipes to cleanse hands and arms before
applying barrier cream.
• When moving from one area of the farm to another, spray rubber boots with a disinfectant degreaser
thoroughly before and after entry.
• When using disinfectants under the suggested environmental, animal, and food/water equipment
protocols, staff must wear the appropriate protective gear, including masks, goggles, waterproof boots,
overalls, gloves and hair nets. Incinerate all disposable materials after each use. appropriate protective
gear, including masks, goggles, waterproof boots, overalls and gloves.

Feed & Water Equipment
Healthy birds are less susceptible to disease, and the key to a healthy bird is a healthy diet. To help keep feed fresh and
uncontaminated, store it in a secure area that is free of entry points for rodents and birds. Clean feed and water storage areas with
disinfectant before refilling.
When transferring feed from the feed storage area to the live animal area, be sure all workers clean their hands and arms and
wear the appropriate protective clothing, including disinfected waterproof boots. Serve hens feed in dishes in front of their cages.
Remove and clean feeding dishes twice daily, and remove, discard and incinerate all spilled feed from the feeding area. Feeders can
be cleaned at a location separate from the main animal-holding area. Irrigated water systems should also be cleaned twice per day
with disinfectant.
For effective disease prevention, implement a thorough disinfection program for all feeders, drinkers, holding tanks and pipe work
that carry feed and water from storage areas to live animal areas.
To prevent disease spread through contaminated feed
and water equipment, the following steps should be
considered:
• Provide a healthy and well-balanced diet for all birds.
• Retain samples of every batch of feed grain for subsequent
testing should a problem occur.
• Thoroughly disinfect all feed and water storage tanks as well
as the attached pipe work that bring feed and water to the
animals. Clean water bowls and feeders twice daily using an
effective disinfectant.
• Clear any spilled feed and remove from the feeding area
before birds can eat it.
• Ensure that all workers wash their hands and arms with an
antimicrobial hand cleaner and apply a microbial barrier
cream to reduce the risk of feed contamination.
• Soak all small-scale feed equipment in an effective
disinfectant solution overnight. Be sure to rinse thoroughly
after cleaning.

This booklet was written and published by Dow Microbial Control, a business unit of The Dow Chemical Company, to help reduce
the spread of viral diseases and their causative agents including Avian Influenza, Newcastle Disease, Avian Reovirus, Avian Rotavirus,
Human Corona Virus (the viral type associated with SARS), Marek’s Disease Virus, Infectious Bronchitis Virus, Infectious Bursal
Disease Virus and Avian Laryngotracheitis.
The GLUTEX™ product portfolio for animal housing biosecurity is based on the active molecule, glutaraldehyde.
Only GENUINE GLUTARALDEHYDE delivers the true benefits of glutaraldehyde.
Pathogens cause deadly diseases that devastate animal populations and destroy a farm. If kept uncontrolled, it may lead to severe
outbreaks including ailments and even death to animals and people associated with it. Using GENUINE GLUTARALDEHYDE can help
solve these problems. Unfortunately, inexpensive non-genuine glutaraldehyde products have emerged throughout Asia. Disreputable
blenders, formulators, producers and traders blend formaldehyde and other chemicals to reduce their costs, delivering a product they
pass off as glutaraldehyde. These non-genuine blends can put customers at risk for performance and financial loss, while putting the
workers and the environment at risk.
Dow Microbial Control can help protect your farm against bacteria, viruses and fungi using GLUTEX™ that is made with GENUINE
GLUTARALDEHYDE. GLUTEX™ Antimicrobials target pathogens that cause deadly animal diseases and helps control microorganisms
before they spread, which reduces your risk and maximizes your profits. It is very effective against animal and poultry housing,
hatcheries, farm vehicles and equipment, so that both your animals and your business remain sustainable and safe.
