No new bird flu virus continued to be detected on some 26 dead crows, quails, pigeons and sparrows in over 10 townships in Myanmar's Yangon amid the latest outbreak of the disease in the former capital city since early last week, an official newspaper reported Monday.
The dead fowls, after undergoing laboratory test on Sunday, found no new bird flu virus, the New Light of Myanmar quoted the Livestock Breeding and Veterinary Department (LBVD) as saying.
The LBVD has urged breeders to control the movement of crows and sparrows which are likely to carry bird flu virus and to avoid eating, selling and undisciplined dumping of dead fowls and birds as well as to pay serious attention to bio-security at poultry farms.
It was the second day that no new bird flu virus continued to be detected following Saturday when some dead fowls, after being tested, found no such virus and was then concluded that the deaths might be due to the residue of disinfectant used in the poultry farms among measures taken against the bird flu outbreak.
The LBVD had also urged pet keepers to keep their dogs and cats away from eating dead crows, sparrows, pigeons and wild birds, and not to directly use concentrate disinfectant on infected farms.
However, the deaths of some layers, found in the township of Hlaingtharya earlier on Friday, was detected with suspicious H5N1 virus.
So far, there has been four townships in Yangon -- Mayangon, Thingungyun, Insein and Hlaingtharya detected with the bird flu virus.
More preventive measures against the avian influenza are continuously being taken in the aftermath of its outbreak in the city which include poultry culling, pesticide spraying in the areas where some layers, domestic chickens, ducks and crows were found dead and local people are being urged to contact the department when finding dead fowls and birds.
Days after the outbreak, the prices of chickens declined from 10 to 20 percent in Yangon livestock markets.
Suspicious avian influenza was first 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.
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.
Deepened detection of the root cause of the disease has been underway since then.
When the bird flu was first reported early last week, 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 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 then 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 has been no human cases detected with H5N1 in the country.
