Ministry says it hasn't been covering up any outbreaks [SIZE=-1]

<!--img--> <!--/img--> The Agriculture and Cooperatives Ministry yesterday denied vehemently it had been covering up fresh outbreaks of bird flu following reports of mass deaths of poultry over the past few weeks. It could not possibly conceal such outbreaks because its bird flu surveillance and diagnostic operations were monitored closely by various agencies such as the World Organisation for Animal Health, said Charal Trinvuthipong, assistant to the agriculture and cooperatives minister.
Covering up bird flu outbreaks would also end up doing more harm than good to the country, he added.
Officials had conducted so-called ''X-ray'' bird flu surveillance tests nationwide from last month and about 53,000 fowl tissue samples tested negative for bird flu, Mr Charal said.
Mr Charal was responding to a pointed query from an outgoing senator, Nirun Phitakwatchara, a member of the Senate's panel on human development and social security, who suspected the ministry had been concealing the recurrence of bird flu after poultry deaths on a large scale were reported in many areas devastated by previous outbreaks.
The ministry was accused of mismanagement and covering up the disease when it first struck the country in early 2004.
About 61 million poultry died or were culled in the first outbreak. But H5N1 has not been detected in Thailand since November.
''Our ongoing active bird flu surveillance operations may have misled people into believing there have been bird flu outbreaks. It's true that the disease, which is now endemic to Thailand, may emerge again today or tomorrow. However, it is impossible for us to cover up outbreaks if they do occur,'' said Mr Charal.
The Livestock Development Department reported on Sunday that fowl died in huge numbers in 430 tambons in 50 provinces. The department's laboratory tests confirmed that 351 tambons were free of bird flu, while 79 tambons in 23 provinces were still awaiting test results.
Meanwhile, more chicken deaths were reported yesterday, including about 1,000 in Phichit and 300 in Phitsanulok provinces. The test results on the samples are due to be released next week.
Pornchai Chamnanpood, director of the department's National Institute of Animal Health, a focal point for diagnosing bird flu in animals, also dismissed the allegation that the institute was ''ordered'' to cover up bird flu detections.
He said the fowl deaths were caused by
weather fluctuations and environmental changes, which had prompted some fungi and bacteria to grow more rapidly, devastating livestock. The lethal organisms had been found in some chicken carcasses.However, a high-level source at the department said about 10% of samples were unsuitable for diagnosis of H5N1. The bird flu virus could be elusive and impossible to detect in some cases.
Yukol Limlamthong, head of the Livestock Development Department, said that since the disease was already present in the country, the department did not rule out a possibility of a re-emergence of the virus. The department had been upgrading poultry farm management along with imposing strict controls on fowl movements and carrying out frequent disinfections of bird flu-risk areas as part of the bird flu prevention and surveillance scheme.
