Bird Flu confirmed on new locations in Gauteng and Mpumalanga

JOHANNESBURG, July 12 – The Highly Pathogenic Avian Influenza (HPAI) H5N8 virus — commonly known as bird flu — has been confirmed on two new locations on farms in Gauteng and Mpumalanga, the department of agriculture, forestry and fisheries said on Tuesday.

“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 department said.

“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 department said that the new Poultry Disease management Agency (PDMA) system which registers people buying and selling live chickens made it possible to trace the culls.

The PDMA registration process of sellers and traders of live chickens has progressed well and a number of initial challenges were ironed out, the department said.

“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 new discovery brought the total number of affected properties to four. The depopulation of the two poultry sites affected in June has been completed.

“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,” it said.

“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.”

The export of raw meat, eggs and live birds from South Africa to some trade partners was disrupted, as one of requirements for the certification is country freedom from HPAI, which cannot be provided since June 22.

The department said that the export of products, which had been processed to ensure destruction of the virus, was also continuing, unless the trade partner 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 department said.

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, it said.

“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.
