The Myanmar Livestock Breeding and Veterinary Department (LBVD) is taking more measures against bird flu in Yangon, the official newspaper The New Light of Myanmar reported Saturday.
Some preventive measures such as poultry culling, pesticide spraying have been taken in the areas where some layers, domestic chickens, ducks and crows were found dead, the paper quoted the LBVD as saying, requesting the public to contact the department when finding dead fowls and birds.
The death of 11 layers was found in Hlinethaya township in Yangon on Friday and suspicious avian influenza was further detected through the rapid test, the paper disclosed.
According to a statement of the department Thursday, suspicious avian influenza was detected in a small private poultry farm in northwestern Yangon's Mayangon suburban township after laboratory test was done on some dead chickens on Tuesday.
Under the risk prevention program, chickens of the farm were culled and buried and the whole farm was sterilized by spraying with pesticide, the statement said.
The authorities have placed the areas in a radius of one kilometers (km) to the affected farm as restriction zone and three townships of Mayangon, Yankin and South Okkalapa in a radius of 10 km as bird movement control zone, temporarily closing livestock trading markets within the control zone for three weeks.
The authorities have also warned farms in Yangon to prevent outsiders from entering them and to keep farm buildings from wild bird intrusion.
Deepened detection of the root cause of the disease is underway.
According to the authorities' report to the United Nations Food and Agriculture Organization (FAO) on Wednesday, a total of over 1, 300 chickens suspected of carrying the deadly H5N1 virus were slaughtered as an initial step by the authorities to deal with the fresh outbreak of the disease.
The destroyed chickens included 500 small hens, 360 laying hens and 500 hatched chickens, the FAO quoted the authorities as saying.
Further confirmation on the virus by international authoritative institutions is being expected.
The recurrence of the deadly influenza came nearly six months after Myanmar declared itself bird-flu-free in the country in September last year after making sure that no virus had been present in the country during a three-month program on detection of avian influenza carried out with the cooperation of foreign experts.
Myanmar was first struck by an outbreak of H5N1 bird flu in March 2006 in two divisions of Mandalay and Sagaing, and since then altogether 342,000 chickens, 320,000 quails and 180,000 eggs as well as 1.3 tons of feedstuff were destroyed at 545 poultry farms.
So far, there have been no human cases detected with H5N1 in the country.
