      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

      ADDITIONAL INFORMATION ON AVIAN INFLUENZA

      1. What is bird flu?
      a. Just like flu, it is a winter disease
      b. It affects all types of birds, and some show signs more than others
      c. It moves from chicken to chicken easily and very quickly

      2. How do you stop it?
      a. Owners of chickens should prevent contact with wild birds by avoiding
      i. feeding chickens outside
      ii. Leaving open water sources
      iii. Leaving chickens roaming outside and picking up wild bird faeces
      b. When chickens are sick, do not move them from the premises
      c. Be careful of vehicles and people coming on to your premises from affected areas
      d. When your chickens are sick, do not move eggs, chickens, bedding, manure and any
      other tools around and to other owners.
      e. When your chickens are sick, put them in a locked up place and ensure they do not
      make contact with other chickens and wild birds; also make sure you are thoroughly
      clean before going to another premises with chickens.

      3. Does it affect people?
      a. Generally not; however, people that work closely with large numbers of chickens may
      contract the disease.
      b. This type of bird flu is not known to have caused any death or serious sickness in
      people.

      4. How do you see it?
      a. The chickens will look sick and then they die in numbers higher than normal

      5. What do you need to do?
      a. Contact your local agriculture official to assist. The Department will pay for samples
      to rule out Avian Influenza if sent to the ARC-OVR through the State Vet office.

          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.
