MEDIA STATEMENT 22 JUNE 2017
AVIAN INFLUENZA CONFIRMED IN MPUMALANGA
Following the outbreak of Avian Influenza that was announced in Zimbabwe on 2 June
2017, The South African Veterinary Authority was today notified on of high mortalities
on a breeder flock in Villiers close to the Mpumalanga Provincial border.
Samples were collected on the farm and have yielded a positive result for a Highly
Pathogenic Avian Influenza, H5N8. The Department has agreed with the company to
euthanize the birds in affected houses in collaboration with the NSPCA.
The affected property has 12 self-contained sites with a total of approximately 285 000
birds, and so far only one self - contained site, with approximately 24 000 birds has
been affected. As part of the emergency response, the farm has been placed under
quarantine and Veterinary services will continue to monitor the farm.
The Mpumalanga Veterinary Authorities are on the farm, assisting with quarantine
implementation, culling and disinfection of the farm. The affected farm is on the banks of
the Vaal River and it is suspected that wild birds may be involved. The influenza is
carried by live birds which make it difficult to control and contain to a particular area. We
have intensified our early detection and requested owners to enhance their biosecurity
in order to prevent contact with wild birds.
Vaccination against Avian Influenza is prohibited by law. There are several reasons for
not allowing vaccination of chickens, and the most pertinent are that vaccinated birds
mask the disease and therefore create an endemic situation; surveillance for absence of
disease is also impossible in vaccinated birds as they all test positive.
The department has sent out notices to all poultry owners, outlining the biosecurity
measures they have to take, and detailing how the surveillance will be conducted. This
can be found on the DAFF and SAPA websites.
To report any high death numbers of wild birds please contact your local State Vet,
Animal Health Technician or Extension Officers

MEDIA BRIEFING BY MINISTER SENZENI ZOKWANA
AVIAN INFLUENZA OUTBREAK IN SOUTH AFRICA
29 JUNE 2017
Good morning
The Department alerted poultry owners about the eminent threat of Avian Influenza
when Zimbabwe reported their first case at the end of May. The disease, which at
that time had been reported in 14 countries, 2 of which were in Africa, had been
confirmed in Zimbabwe making it the third country in Africa to be affected.
Avian Influenza is an influenza virus, and is classified as either highly pathogenic or
low pathogenic by the World Organisation for Animal Health. The type that has been
reported is the highly pathogenic one and is extremely contagious.
The Department, in its alert notification, called for all chicken keepers to observe
basic biosecurity measures in order to prevent contact with wild birds. This can be
achieved in commercial farms by improving biosecurity and in free range farms by
simply removing feed and water from where it attracts wild birds.
Despite the warnings, the disease still managed to get into our flocks. Two cases,
one in a broiler breeder farm in Villiers and another in an egg laying farm in
Standerton, were reported since 22nd of June. Both these farms are in the
Mpumalanga province. There seems to have been confusion with the location of one
farm which is near Villiers, as its closest town. I confirm that this farm is on the
Mpumalanga side of the provincial boundary. No cases have been reported so far in
the Free State, or in any other province.
Our team of veterinarians has swiftly responded to this threat. We have placed the
affected farms under quarantine and the affected birds have been euthanised and
the eggs destroyed. Approximately two hundred and sixty thousand (260 000) birds
have been culled.
Section 19 of the Animal Diseases Act, gives the Director Animal Health the legal
mandate to compensate for any animals or birds killed by the state pursuant to any
disease control measure. The Director of Animal Health will consider each case on
its own merit.
There have been several calls to permit vaccination against the disease; I have been
advised by my team of experts that this will not be in the best interest of both the
country and the producers. Vaccination of birds will create an endemic situation,
affect surveillance efforts and affect our export certification because all our trade
partners only want products from a country that is free of avian influenza where
vaccination is not practised.
In order to contain the disease, our team called for the ban on the sale of live
chickens to manage the further spread. This triggered a nation-wide concern since a
number of livelihoods had been affected. However this measure was imposed in the
interest of the country and the poultry producers at large, and I can assure you that it
was not taken lightly.
My team has since met with the Poultry Producers and have devised a solution that
will provide the desired disease management outcomes and improve traceability,
while ensuring that micro businesses continue with their operations. The buyers or
sellers of more than 5 live chickens for any purpose other than direct slaughter at a
registered abattoir will be subjected to the following conditions:
1. The sellers of live chickens, including commercial farmers, as well as the
traders who buy and resell these chickens must register with the Poultry
Disease Management Agency (PDMA). The Director Animal Health, of the
DAFF has authorised the PDMA to register and keep records of all parties
selling and buying live chickens. The PDMA is an independent organization
and all information about the trade of live chickens will be kept strictly
confidential.
2. Only registered sellers and buyers are allowed to trade and it is the
responsibility of both the seller and the buyer to ensure that their counterpart
is registered.
3. Farmers may only sell live chickens certified as healthy by a veterinarian or
Animal Health Technician.
4. Traders may only sell healthy chickens and must keep records as prescribed.
5. Sellers and buyers registering with the PDMA would have to sign an
undertaking to adhere to the required control measures.
These conditions apply to sellers of live broiler chickens, live spent layer hens, live
spent breeder birds, point of lay pullets and any chickens that may fall into these
categories. The conditions also apply to any buyers and traders who buy more than
5 live chickens that fall into the above categories.
All stakeholders are implored to comply with the registration and other requirements
that are designed to allow the trade of live chickens to continue without
compromising animal health. Depending on the level of compliance that is achieved
with these conditions, the Director Animal Health will review future requirements for
blanket bans.
Registration forms for sellers and buyers are available on the DAFF
(www.daff.gov.za) and PDMA (www.poultrydiseases.co.za) websites and further
information can also be obtained from the PDMA (at 012 529 8298).
We request utmost cooperation of all affected parties in order to prevent further
spread of the current outbreak and enhance the disease management efforts.
The Department wishes to reiterate that the type of virus we are dealing with, does
not affect people, as has been confirmed by the World Health Organisation and the
World Organisation for Animal Health.
The meat that is on the shelves is safe to eat as it has gone through a process of
meat inspection and certified fit for human consumption.
A number of trade partners, have suspended trade of raw meat, eggs and live birds
from South Africa. This is mainly because the South African veterinarians have to
certify that the country is free of Avian Influenza, and since the 22nd June, they could
not provide this certification. However, processed meat is considered safe for trade,
and some countries still accept this.
South Africa introduced the concept of compartments in line with the World
Organisation for Animal Health (OIE) guidelines; raw meat, eggs and live birds
originating from these compartments have been accepted by most trade partners.
Our team is already in negotiations with these trade partners to accept our products
from these registered compartments.
Chicken owners, farmers and the public should remain vigilant and all cases of high
mortalities in chickens and other birds should be reported to the nearest State
Veterinarian.
I wish to thank the Poultry Producers for their cooperation and consistent
engagement with the Department. I also wish to thank my team for the swift
response and their dedication.
Ke a leboha.

MEDIA STATEMENT 11 JULY 2017
UPDATE ON AVIAN INFLUENZA H5N8 OUTBREAK IN SOUTH AFRICA
The HPAI H5N8 virus was confirmed in two further locations in South Africa, bringing the total of
affected properties to four. The new locations involved commercial layer chickens on farms in
Gauteng and Mpumalanga.
The two farms were immediately placed under quarantine by the state Veterinarian. The quarantine
includes, as a minimum, a prohibition of the movement of chickens and chicken products onto and off
the farm. The necessary measures have been taken to contain and eliminate the disease as
efficiently as possible on both farms.
Forward tracing was done and cull chicken depots were identified, which had received live cull
chickens from one of the affected farms in the last 21 days. The records of these cull depots are
being followed up to trace as many of these chickens as possible. The new Poultry Disease
management Agency (PDMA) system of registration of persons buying and selling live chickens made
it possible to trace these culls.
The PDMA registration process of sellers and traders of live chickens has progressed well and a
number of initial challenges were ironed out. All role players in the poultry industry involved in the
buying and selling of live chickens are strongly encouraged to comply with the registration and other
requirements that are designed to allow the trade of live chickens to continue without compromising
animal health.
The depopulation of the two poultry sites affected in June is complete. The carcasses, waste
material, affected eggs and manure have been contained and will be dealt with to ensure prevention
of spread of the disease, as well as to prevent contamination of the environment.
Export of chickens and chicken products from registered HPAI free compartments is continuing to
countries that accept guarantees from such compartments. There is good cooperation from registered
compartments to increase the testing frequency to monthly testing.
Exports of raw meat, eggs and live birds from South Africa to some trade partners have been
disrupted, as one of requirements for the certification is country freedom from Highly Pathogenic
Avian Influenza, which cannot be provided since 22 June 2017. The export of products, which had
been processed to ensure destruction of the virus, is also continuing, unless the trade partner has
raised an objection.
The H5N8 virus does not affect humans, Department of Health through the National Institute of
Communicable Diseases tested workers from the affected farms and no human cases have been
detected.
The HPAI H5N8 viruses that have been isolated from these outbreaks are similar to the viruses
isolated from Zimbabwe in June 2017 and from Egypt in 2016, which makes the likelihood of the
involvement of wild birds high. Chicken owners and farmers are encouraged to prevent contact of
their chickens with wild birds as much as possible.
Increased surveillance in wild birds, commercial chickens and backyard chickens is continuing.
Chicken owners, farmers and the public should remain vigilant and all cases of high mortalities in
chickens and other birds should be reported to the nearest State Veterinarian.
The public is advised to avoid any gathering of chickens for shows, auctions and similar activities.
However, should such activities continue, the organizers are advised to liaise with the State
Veterinary Authorities and the auction houses must also be registered with the PDMA.

Possible Incidence of Bird Flu in the Western Cape
14 August 2017
Listen
The Western Cape Department of Agriculture is investigating possible incidences of Highly Pathogenic Avian influenza (HPAI), type H5N8, in two ostrich farms in the Heidelberg area.
Avian influenza is a controlled disease in terms of the Animal Diseases Act, 35 of 1984.
Investigations on the farms are in progress and both farms have been placed under quarantine. Quarantine measures entail no movement of birds to and from the affected properties will be allowed. People and vehicles will have to adhere to strict hygiene measures.
Thirteen outbreaks have occurred in South Africa since June this year, in Mpumalanga and Gauteng. The outbreaks involved seven commercial chicken farms, two groups of backyard chickens, three sets of wild birds and one group of domestic geese.
Avian influenza is a viral respiratory disease of birds believed to be transmitted by wild migratory birds. In Southern Africa, the H5N8 strain of the disease also affected the poultry industry in Zimbabwe, where thousands of commercial birds have died or had to be culled.
This strain of the virus has so far shown no sign of being infectious to people. Constant monitoring of exposed people in South Africa has supported this.
Ostrich and chicken meat on sale in retail outlets is safe for human consumption.
Avian Influenza is primarily spread by direct contact between healthy and infected birds, or through indirect contact with contaminated equipment or other materials. The virus is present in the faeces of infected birds and in discharges from their noses, mouth and eyes. The virus can spread into domestic flocks kept outdoors through faecal contamination from wild birds, whereas infection among indoor flocks is spread via airborne discharges and faeces.
There is currently no preventive vaccine or treatment for HPAI H5N8. Current practice in most regions of the world requires the culling of infected birds. There is no benefit to be gained in attempting to control the virus in wild birds through culling or habitat destruction.
General recommendations:- It is very important to report sick or dead birds - both wild birds and poultry - to local authorities (veterinary services, public health officials, community leaders etc.) Details of local state veterinarians can be found at:http://www.elsenburg.com/services-and-programmes/veterinary-services-0#s...
- Farmers and poultry producers should step up their biosecurity measures in order to prevent potential virus introduction from wild birds or their faeces;
- It is important to keep poultry and other animals away from wild birds and their body fluids, through screens, fencing or nets;
- Commercial poultry operations and backyard poultry owners should avoid the introduction of the virus through contaminated clothes, footwear, vehicles or equipment used in waterfowl hunting.
- The sellers of live chickens, including commercial farmers, as well as the traders who buy and resell these chickens must register with the Poultry Disease Management Agency (PDMA). The national Director Animal Health has authorised the PDMA to register and keep records of all parties selling and buying live chickens. The PDMA is an independent organisation and all information about the trade of live chickens will be kept strictly confidential.
- Only registered sellers and buyers are allowed to trade and it is the responsibility of both the seller and the buyer to ensure that their counterpart is registered.
- Farmers may only sell live chickens certified as healthy by a veterinarian or Animal Health Technician.
- Traders may only sell healthy chickens and must keep records as prescribed.
- Sellers and buyers registering with the PDMA would have to sign an undertaking to adhere to the required control measures.

Avian Influenza Confirmed in Western Cape
15 August 2017
Listen
The Western Cape Department of Agriculture has confirmed the presence of Highly Pathogenic Avian influenza (HPAI), type H5N8, in two ostrich farms in the Heidelberg area.
Avian influenza is a controlled disease in terms of the Animal Diseases Act, 35 of 1984.
Vets from the Western Cape Department of Agriculture detected HPAI during routine testing.
Last week, throat swabs tested positive for HPAI. Both farms were placed under quarantine immediately, and no birds are allowed to enter or leave the affected properties. There are around 1000 ostriches on both farms.
To ensure the accuracy of the first test, and because the ostriches are not showing any clinical signs of the illness, vets continued their testing campaign. There have been no reported bird deaths in the area.
At this stage, it appears that the incidence has been confined to the two properties. Farms within 3km of the affected farms will be placed under quarantine and testing in the surrounding areas will continue.
No decision to cull has been taken and discussions are ongoing.
It is suspected that wild birds are the source of the infection.
Thirteen outbreaks have occurred in South Africa since June this year, in Mpumalanga and Gauteng. The outbreaks involved seven commercial chicken farms, two groups of backyard chickens, three sets of wild birds and one group of domestic geese.

Commercial poultry operations and backyard poultry owners should avoid the introduction of the virus through contaminated clothes, footwear, vehicles or equipment used in waterfowl hunting.
Because of the HPAI H5N8 outbreaks, the buyers or sellers of more than five live chickens for any purpose other than direct slaughter at a registered abattoir will be subjected to the following conditions (quoting Media Briefing by Minister Senzeni Zokwana, Avian Influenza Outbreak In South Africa, 29 June 2017, Department Agriculture Forestry & Fisheries):
The sellers of live chickens, including commercial farmers, as well as the traders who buy and resell these chickens must register with the Poultry Disease Management Agency (PDMA). The national Director Animal Health has authorised the PDMA to register and keep records of all parties selling and buying live chickens. The PDMA is an independent organisation and all information about the trade of live chickens will be kept strictly confidential.
