Pig disease recurs in northern Vietnam
Animal health authorities reported Sunday an outbreak of the blue-ear pig disease, or Porcine Reproductive and Respiratory Syndrome (PRRS), in the northern province of Ha Tinh after a pause of four months nationwide.
The agency said a total of 2,460 pigs in local farms have been recently infected with the virus.
Local animal health centers are requested to take swift action to quarantine, sterilize infected areas, cull affected pigs, and restrict transport of pork products in and out of outbreak areas.
PRRS in pigs is caused by the Lelstad virus, which causes ears to turn blue, appetite loss, high fever, miscarriage, premature delivery, coughing, respiratory problems, and death in extreme cases.

VietNamNet Bridge – The virus that is causing the blue ear epidemic in Vietnam is highly toxic and extremely dangerous. It is similar to the virus in China, reported the Ministry of Agriculture and Rural Development.
A Deputy Minister of Agriculture and Rural Development said Porcine Reproductive and Respiratory Syndrome (PRRS) or blue ear epidemic is developing complicatedly and it may spread widely in the coming days.
By April 21, the disease was reported in 657 communes of ten provinces, attacking 222,000 pigs, including over 221,300 culled, said Head of the Veterinary Agency Bui Quang Anh. The ten stricken provinces are Ha Tinh, Quang Nam, Thanh Hoa, Nghe An, Lam Dong, Thua Thien-Hue, Thai Binh, Thai Nguyen, Nam Dinh and Ninh Binh.
The development of the disease in Thanh Hoa, Nghe An and Ha Tinh may be less critical in the coming days, but the situation may be worse in Thua Thien-Hue and Lam Dong provinces, experts said.
In Thai Binh province, by April 21, blue ear disease had occurred in seven communes in Vu Thu and Dong Hung districts. In Thai Nguyen province, five communes and towns were reported to have caught the disease between April 17 and April 20.
Notably, the disease has spread to the country’s key areas for animal husbandry like Ninh Binh, Nam Dinh and Thai Binh, while the transport of pigs to Quang Ninh to export to China across the border is a threat to dispense blue ear everywhere.
The Ministry of Agriculture and Rural Development has sent an urgent message on the control of the transportation of pigs and conditions for small-volume exports of pigs and pork products during the period of blue ear disease.
As of April 24, pigs and unprocessed pork products shall not be transported via disease-hit localities such as Thanh Hoa, Nghe An and Ha Tinh until the localities are recognised as being free of the disease.
If pigs and pork products have to be transported via the localities, the transportation of the pigs and pork products shall have to be allowed by the People's Committees of the provinces and have to occur on specific roads designated by the provincial steering boards on the control and prevention of blue ear disease of the localities.

500 M pigs in China, 1M-2M died in 2007 = 0.3%
Plus sharp increase in pig-prices in China
are the Chinese numbers credible ?
can someone find the official number of pigs from the 2007-count ?
(statistical bureau or agriculture ministry, I don't remember,
we had it in earlier threads)
an update on pigprices were also good

Nearly 82,000 pigs in Vietnam's two central provinces of Nghe An and Ha Tinh and northern Thanh Hoa province have recently infected with Porcine Reproductive and Respiratory Syndrome (PRRS), known as blue ear disease, according to a local veterinary agency on Thursday.
The Vietnamese Ministry of Agriculture and Rural Development has asked local relevant agencies to kill all infected pigs to prevent the spread of the disease, the ministry's Department of Animal Health said.
The PRRS is now hitting four Vietnamese localities, Nghe An, HaTinh, Thanh Hoa and central Quang Nam province, said the department.
The PRRS was first recognized in the United States in the mid-1980s and is now present in most pig producing countries. The symptoms include reproductive failure, pneumonia and increased susceptibility to secondary bacterial infection.:tiphat:

Vietnam initially controls pig disease
14:43' 30/04/2008 (GMT+7)
VietNamNet Bridge – Vietnam has initially put the blue ear disease on pigs under control, announced the Veterinary Department’s Vice Head Hoang Van Nam on April 29.
The Porcine Reproductive and Respiratory Syndrome (PRRS) (known as blue ear disease) have so far found in 10 provinces, including northern Thai Nguyen, Thai Binh, Nam Dinh and Ninh Binh provinces, central Thanh Hoa, Nghe An, Ha Tinh, Quang Nam and Thua Thien-Hue provinces, and Central Highlands Lam Dong province.
To fight the epidemic more effectively, the Ministry of Agriculture and Rural Development has asked the World Organisation for Animal Health (OIE) and the Chinese Veterinary Administration to send experts to Vietnam in May.
The ministry has also signed with the Chinese side a contract to import 1 million doses of anti PRRS vaccine.
In addition, localities have been urged to tighten control over transportation of pigs and their products, as well as butchery.
Last week, northern mountainous Son La province discovered a new outbreak of bird flu, joining southern Can Tho Province in the list of the disease-stricken localities.

Blue ear epidemic is growing in the south of Vietnam and local authorities can’t control the situation, said Deputy Director of the Southern Veterinary Agency Nguyen Xuan Binh.
The disease has expanded to Binh Phuoc, Dong Nai and Lam Dong provinces. Ill pigs are also being transported to HCM City.
Director of the Department of Agriculture and Rural Development of Dong Nai province, Nguyen Van Giau, said thousands of workers at southern industrial zones have to buy cheap pork (ill pigs) because their income is too low.
Deputy Minister of Agriculture and Rural Development Bui Ba Bong pointed out two things that have facilitated the rampancy of blue ear: lack of supervision over the disease and improper solving of the first outbreaks. :tiphat:

Nghe An province announced the existence of blue ear epidemic on Sunday, April 6 and its compensation for families that have pigs culled, VND20,000/kg. Two days ago, over 200 pigs got ill and died of blue ear disease in two communes in Dien Chau district, Nghe An province. Local authorities have banned the trade and transport of pigs from and to disease-stricken areas but local people are still trying to unload their pigs. In Ha Tinh province, blue ear epidemic has been reported in 35 communes, with over 7,000 ill pigs and 5,300 pigs culled. In Thanh Hoa province, the disease has spread to 134 communes, affecting 30,600 pigs, including 7,500 culled. The local government is giving VND20,000/kg to breeders whose pigs are culled and has asked all slaughtering houses to stop operating and banned the transport and trade of pig and pork meat in the whole province from April 6 to 15. In Quang Nam province, seven months after the local administrative lifted the ban on pork, the disease appeared again on April 3. Minister of Agriculture and Rural Development Cao Duc Phat on April 4 issued another dispatch asking blue-ear-hit provinces to cull all ill pigs immediately; take strict measures to prevent the disease; and regularly report the situation to the Ministry of Agriculture and Rural Development and the Government Office. Previously, Phat issued a dispatch on April 1 asking northern and central provinces to supervise blue ear and ban the transport of pigs from disease-stricken areas.:tiphat: |

So far, around 137,000 pigs are reported as having the disease. 124,000 have been culled, a record high number. In Nghe An, one week after announcing the blue ear epidemic, the disease has covered 27 communes with nearly 1,700 pigs culled. In Thanh Hoa, up to 299 wards and communes have pig disease, totalling 115,000 ill pigs and 104,000 culled. In Ha Tinh, 57 communes are reported as having blue ear epidemic. Of nearly 20,000 ill pigs, over 19,000 have been culled already. The government has decided to allot VND120 billion to curb the epidemic. |
Blue-ear pig disease under control
22:48' 04/05/2008 (GMT+7)
VietNamNet Bridge - Blue-ear pig disease has been kept under control with only two fresh outbreaks detected on May 2. However, the Veterinary Department has warned that the epidemic could spread further as the warm weather creates ideal conditions for the virus to thrive.
Fresh outbreaks were detected on May 2 in two communes in northern Nam Dinh and central Nghe An provinces. Elsewhere around the country, 1,143 more pigs were infected with the virus and 1,234 infected pigs were culled.
Currently, 10 provinces namely Ha Tinh, Quang Nam, Thanh Hoa, Nghe An, Lam Dong, Thua Thien-Hue, Thai Binh, Thai Nguyen, Nam Dinh and Ninh Binh have not passed the 21-day threshold to declare themselves free from the disease.
The Ministry of Agriculture and Rural Development (MARD) has asked the world organisation for animal health (OIE) and China’s general department of animal health to send their experts to Vietnam in May to help the country stamp out the epidemic effectively. The ministry has also signed a contract with China to import 1 million doses of blue-ear vaccine.
The ministry has also asked all localities to keep a close watch on the transportation, slaughtering and trading of pig products.
MARD will host a blue-ear pig disease conference in HCM City on May 8.

Pig epidemic spreads in north Vietnam
Blue ear pig disease has spread to the northern province of Thai Nguyen, raising to eight the total number of provinces affected by the disease, said the Animal Health Department Saturday.
According to the department, any province in which no new cases have been recorded in 21 days is considered no longer affected.
The disease, also known as Porcine Reproductive and Respiratory Syndrome (PRRS), has most recently hit two farrows of pigs in Phu Binh District’s Tan Duc and Phu Luong communes in Thai Nguyen.
On Friday, the epidemic hit 8,820 pigs in 35 communes nationwide, said the department.
According to the agriculture ministry, PRRS first hit Vietnam in March last year.
PRRS in pigs causes ears to turn blue, appetite loss, high fever, miscarriage, premature delivery, coughing, respiratory problems, and death in extreme cases.
The illness is caused by the Lelstad virus.

| Millions of Pigs Culled as Epidemic Spreads | ||
Those in charge of controlling the spread of Porcine Reproductive and Respiratory Syndrome Virus have been too complacent, Deputy Minister of Ministry of Agriculture and Rural Development Bui Ba Bong told a Sai Gon Giai Phong reporter.
The epidemic has spread across the central region and has developed in a complicated way. Mr. Bong explained that some farmers sell their diseased pigs without veterinary supervision, which has caused a major outbreak in the central region. The disease will spread north and south if those in charge of controlling the disease relax their guard, he added. The public suspects that his ministry had a slow reaction to the disease, he said. Since the pandemic started in the central province of Ha Tinh, the ministry has sent a dispatch instructing provincial authorities to tighten their supervision of the disease. Yet it is difficult to supervise pig slaughter, sale and transportation due to a shortage of human resources. The disease spreads rapidly and farmers have little knowledge of how to prevent or control it. Unscrupulous traders are cashing in by buying diseased pork at low prices and then selling it for full price. Diseased pork is often thrown into rivers and reservoirs because many farmers do not realize that this causes the disease to spread. The deputy minister stressed that the Department of Animal Health plan to cull diseased pigs. The entire machinery of state must mobilize and take drastic action to fight this disease, he added. Mr. Bong said that the Ministry of Agriculture provided guidance concerning breeding programs and inoculation, as well as the disinfection of disease-hit areas. The Agriculture and Finance Ministries have agreed to a plan to provide compensation to farmers whose pigs are culled, but are waiting for the government’s approval. To date, the outbreak has affect four central provinces, Ha Tinh, Quang Nam, Thanh Hoa and Nghe An. Thanh Hoa has culled 41 million disease pigs. Veterinarians have done sterilization in affected areas. Inspectors are working round-the-clock to ensure that diseased pork is not transported out of affected villages.:tiphat: |

VietNamNet Bridge – Deputy Prime Minister Hoang Trung Hai called on ministries, sectors and localities to be vigilant as the country's first storm of the year, the Neoguri, was just 240km from the coast of the central provinces Quang Ngai and Khanh Hoa.
According to the head of the National Steering Committee for Floods and Storm Control Cao Duc Phat, cities and provinces should warn fishermen in a timely manner, especially the nearly 9,000 fishermen still working near Truong Sa (Spratlys) archipelago and the sea area between Truong Sa and Hoang Sa (Paracels) archipelago. |
It also mentions that PRDC commonly occurs in pigs 14-20 weeks of age and has a 4-6 % mortality rate largely depending on the particular secondary infections.
It would seem prudent in the work-up of swine with PRRS (esp if it seems to be an atypical or severe outbreak) to test for any novel swine influenza viruses that may be circulating in the area...

Porcine Respiratory Disease Complex
Lawrence D. Firkins, D.V.M., M.S.
01/01/1998
Porcine Respiratory Disease Complex (PRDC) is the result of a combination of multiple infectious agents,environmental stressors and production system challenges. Successful intervention requires accurate diagnosis, properly time vaccinations, strategic use of medication, eliminating environmental stressors, and in some cases, changes in production methods.
The common respiratory agents in PRDC are PRRS virus,swine influenza virus, Mycoplasma hyopneumoniae,Salmonella cholerasuis, and Actinobacillus pleuropneumoniae. Less frequent pathogens include Pasteurella multocida and Porcine Respiratory Coronavirus. It has been suggested that PRDC is theresult of subpopulations of infected carrier pigs and disease-naive pigs undergoing an environmental stress or leading to disease. While the prevalence of PRDC is unknown, it appears to be increasing, especially inmulti-site operations. When PRDC hits a unit, typically 30-70 percent of the pigs will be effected. Mortality will be 4-6 percent or greater depending on the secondary bacterial infections.
PRDC most commonly occurs in pigs 14-20 weeks of age. Affected pigs cough, run fevers, and stop eating. These pigs have a decreased growth rate with pigs growing apart from each other within a pen. Several producers report losing pigs to gastric ulcers during a PRDC outbreak.
Subpopulations of infected and disease-naive pigs are often the result of commingling pigs from different sowherds. This allows pigs of variable immunity and disease carrier status to be mixed within a group.Delaying the targeted weaning age and cross-fostering after Day 1 can also contribute to this mixedpopulation. Despite segregated early weaning, viral diseases can pass from the sow to the pigs.Environmental stressors also contribute. The most common mistake made to set up this situation is not following strict all-out protocol on a room or buildings.
When carrier pigs and naive pigs are in the same room orbuilding, PRDC can result when some stressor initiates disease in a few of the carrier animals. Stressors can include crowding, moving and mixing pigs, temperature changes, and poor air quality during this time ofshifting immune status in the pigs. A few pneumonic pigs can rapidly spread the disease. It is common for the majority of pigs in the group to be PRRS positive. Viral agents such as PRRS or swine influenza can initiate mycoplasmal pneumonia in subclinically infected pigs.
Diagnosis of PRDC requires submission of the proper samples. The key is selecting the proper specimens and collecting them at the proper time. Sending in multiplesamples will increase the likelihood of obtaining a truepicture of what is occurring. Consideration should begiven to submitting live pigs to the diagnosticlaboratory. If this is not possible, fresh samples,fixed samples, nasal swabs, and paired serology can allbe beneficial when attempting to obtain a diagnosis ofthe pathogens involved in causing PRDC.
There are multiple costs associated with PRDC. Th eobvious costs are the increased death loss. Often the most economically significant loss is the decrease in average daily gain and the poor feed efficiency. PRDC also results in challenges to pig flow. Sort loss isincreased due to pigs growing apart. In order to maintain all-in/all-out management of buildings,light-weight pigs must be moved to another facility.
There are methods for minimizing the effects of PRDC once an accurate diagnosis is obtained. It is vital to stabilize the sow herd for the pathogens that are identified in any given situation. This will decrease the chance of the two subpopulations of carrier andnaive pigs developing. Stabilization of the sow herd ismost commonly accomplished through proper immunizationby natural and vaccination methods. Once stabilizationis accomplished, an adequate isolation and acclimation program for replacement animals must be developed. In addition to using vaccines in the sow herd, their use may be necessary in growing pigs to provide uniformimmunity when they reach the 14-18 week age. Strategicuse of antibiotics has proven beneficial in decreasing the effects of PRDC when mycoplasma or a secondary bacteria is involved. Perhaps the most important step that can be taken is strict adherence to pig flow andmanagement rules. Failure to strictly follow such methods as all-in/all-out dramatically increases theodds of a PRDC break.
A control program specifically designed to control PRRS is necessary in the majority of cases. Prior to implementation of control measures, an accurate picture of the pattern of viral transmission within the various stages of production must be obtained. In most cases,PRRS control starts with stabilizing the sow herd. This can be accomplished through use of a modified live vaccine in open sows and replacement gilts. Autogenous killed PRRS vaccines given prefarrowing to sows have been effective in some situations. Based on the pattern of viral transmission and the pig flow management,properly timed vaccination of growings pig may prove necessary. Constant evaluation and manipulation of the immune status of replacement animals will be required.
A swine influenza control program will be needed on many farms with a history of PRDC. Good results have been obtained through immunization of the sow herd. When stabilizing a breeding herd, initially two doses must be given three weeks apart. Booster vaccinations should be given two weeks prefarrowing. Replacement gilts should receive two doses prior to entering the breeding herd.Passive immunity will generally be protective through the nursery stage. Vaccination of pigs in the grower stage will be necessary in some cases to prevent clinical disease.
Stabilization of the breeding herd for mycoplasma is very similar to the protocol recommended for swine influenza. Initially, the sow herd should receive two doses three weeks apart. Sows should also receive a mycoplasma vaccine booster two weeks prior to farrowing. Piglet vaccination requires properly timed doses whichwill vary from herd to herd.
Pulse medication programs can be an effective method to deal with mycoplasma and secondary bacterial infections.Specific antibiotics are used at specific times prior tohistorical disease outbreaks. One program that has been successful involves using antibiotics for three days,then off for four days. This cycle is followed as neededto get through the condition.
Porcine Respiratory Disease Complex remains a challenge to producers. It is now clear that PRRS is generally involved. Influenza can play a role with PRRS or independent of any other viruses.[/B] Mycoplasma is recognized as a major contributor to PRDC. [B]In order to effectively deal with PRDC, the contributing pathogens must first be identified. Modern technologies, along with vaccines and medication, can minimize the effects of this disease. Pig flow management should always be evaluated to assure production rules have not been broken which have resulted in PRDC.

HANOI, April 16 (Xinhua) -- Porcine Reproductive and Respiratory Syndrome (PRRS), known as "blue ear" disease, has recently hit Vietnam's central Thua Thien Hue province, bringing the total number of affected localities to six, according to local newspaper Labor on Wednesday. By April 15, PRRS had stricken 434 communes and wards of 31 districts and towns of the six provinces of Thanh Hoa, Ha Tinh, Nghe An, Quang Nam, Lam Dong and Thua Thien Hue in the central and central highlands regions, leading to the death and the forced culling of over 149,000 pigs, the newspaper quoted the country's Department of Animal Health as reporting. Thanh Hoa alone has 337 communes and wards hit by the disease with a total of over 134,000 affected pigs. PRRS was first recognized in the United States in the mid-1980s and is now present in most pig producing countries. The symptoms include reproductive failure, pneumonia and increased susceptibility to secondary bacterial infection. :tiphat: |

Shallow pig graves stink out central communities
Residents in the north central province of Thanh Hoa are angry about the stench from the shallow burial of tens of thousands of pigs inflicted with blue-ear, a porcine disease.
According to commune residents in districts like Quang Xuong, Dong Son, Thieu Hoa and Trieu Son, the culled pigs infected with Porcine Reproductive and Respiratory Syndrome (PRRS), were covered with only a thin layer of soil.
About three or four days after the mass burial, the pits swelled and cracked oozing fowl smelling grease from the rotting pigs.
Residents said many pits were near residential areas and the fetid smell tortured them day and night.
Other pits were established near paddy fields, causing difficulties to farmers.
Authorities were trying to tackle the pollution by covering the graves with more soil, and spraying sterilizers and deodorants, the deputy head of the provincial Environment and Natural Resources Department, Tran Quang Trung, said.
Regulations specify pits must first be spread with sterilizers and at least one meter of soil should cover the buried animals.
According to the department as of Monday, over 123,000 pigs were reported with blue-ear in some 318 communes in 16 districts in Thanh Hoa.
Around 113,000 were culled.
The blue-ear epidemic has recurred in five provinces - Nghe An, Ha Tinh, Quang Nam and Thanh Hoa in the central region and Lam Dong in the central highlands after it cleared for four months, according to the Ministry of Agriculture and Rural Development Monday.
The ministry has asked localities for stronger supervision and disease prevention, as well as timely culls and quarantine in accordance with standards.
The disease first appeared in Vietnam last March.
PRRS in pigs is caused by the Lelstad virus, which causes ears to turn blue, appetite loss, high fever, miscarriage, premature delivery, coughing, respiratory problems, and death in extreme cases.

Blue ear disease hits pigs in northern Thai Binh Province
14:14' 18/04/2008 (GMT+7)
VietNamNet Bridge – Porcine Reproductive and Respiratory Syndrome (PRRS) has spread to the north, striking pigs in almost 100 households in Thai Binh Province.
The National Animal Diagnosis Centre confirmed on Wednesday that the pig samples from Nguyet Lang Village, Minh Khai Commune, Vu Thu District, sent for testing by the provincial Animal Health Department one day earlier, tested positive for blue ear disease.
Among almost 150 pigs destroyed to prevent the disease from spreading, 43 were sows.
The Agriculture and Rural Development Ministry's Animal Breeding Department deputy director Nguyen Thanh Son had previously said that the loss of a sow was equivalent to loosing 1-1.5 tonnes of pork a year.
The Viet Nam Animal Health Department reported yesterday that 10,400 new pigs were confirmed as infected with the PRRS virus in 39 communes in the country.
About 13,000 sick pigs were destroyed yesterday.
The disease continued to spread to 20 other communes in central Thanh Hoa Province, the locality hit hardest since PRRS returned to Vietnam in early March.
Almost 147,000 pigs in 357 communes in this province were infected and more than 143,000 of them were destroyed.
The total number of pigs infected in the country since the disease returned now stands at nearly 186,400.
Other provinces hit by PRRS are Ha Tinh, Quang Nam, Nghe An, and Thua Thien - Hue in the centre and Lam Dong in the Central Highlands.
Meanwhile, other cities and provinces all over the country stepped up prevention measures to combat the disease. These measures include conducting stricter animal quarantines, inspecting slaughter houses, launching media campaigns to educate farmers how to combat PRRS, disinfecting farms, and setting aside funds to cope with the disease in a timely manner.
The Government announced, last week it would provide VND120bil (US$7.5mil) to curb PRRS in central provinces.
Emergency workshop
At a workshop yesterday, delegates blamed the recent outbreak of PRRS of pigs in northern provinces on a poor inti-epidemic system, shortage of funds and limited awareness of the importance of blue ear disease prevention and protection among farmers and veterinarians.
Delegates at yesterday's workshop pointed out that attention had only been paid to combating the disease rather than prevention.
"It is not really effective to destroy diseased pigs after the epidemic breaks," they told the workshop.
Many warned that northern provinces would suffer from a scarcity of pigs if the epidemic continued to spread as quickly as it has been.
They spoke of Thanh Hoa Province where blue ear disease has spread to an additional 20-30 communes everyday.
Participants at the workshop were told that many provinces and households were still trying to conceal the epidemic.
A series of measures were put forward during the workshop.
Speaking at the event, Agriculture and Rural Development Deputy Minister Bui Ba Bong stressed that due attention must be given to prevent pigs from spreading the disease by checking animals' origins. He also emphasised the need to raise awareness among farmers and veterinarians at the grassroots level.

Pig disease hits two more Vietnamese provinces
www.chinaview.cn 2008-04-04 13:36:56
HANOI, April 4 (Xinhua) -- Porcine Reproductive and Respiratory Syndrome (PRRS) has recently stricken Vietnam's northern Thanh Hoa province and central Quang Nam province, raising the total affected localities in the country to three.
The disease has broken out in a district of Quang Nam, and hit 3,000 pigs in four districts of Thanh Hoa, local newspaper Young People on Friday quoted the provincial veterinary agencies as reporting.
However, the Department of Animal Health under the Vietnamese Ministry of Agriculture and Rural Development has yet to confirm the outbreak in Thanh Hoa.
PRRS has hit pigs in the two central provinces of Ha Tinh and Quang Nam, it said.
PRRS was first recognized in the United States in the mid-1980sand is now present in most pig producing countries. The symptoms include reproductive failure, pneumonia and increased susceptibility to secondary bacterial infection.

In Tien Giang, the disease was found in a flock of 1,500 ducks in Phuoc Lap commune, Tan Phuoc district. These ducks had received the first vaccination on March 1. In Quang Nam, bird flu attacked poultry in Nui Thanh and Tien Phuoc district, where 428 ducks, which were not vaccinated, died. According to Bui Quang Anh, bird flu could appear on a small scale in other provinces where poultry is not vaccinated. As blue ear epidemic is spreading very quickly, the Veterinary Agency on April 8 asked related provinces and cities to address their supervision and control of transport of livestock. So far, nearly 70,000 pigs in the central region have caught blue ear and a record high number of nearly 54,000 pigs have been culled, strongly affecting the animal husbandry sector of the four provinces of Thanh Hoa, Nghe An, Ha Tinh and Quang Nam. “The total number of ill pigs is approximately 70,000, equivalent to the figure of last July, when the blue ear epidemic boomed. However, the loss this time is three times more than last year because only 20,000 pigs were culled last July while it is 56,000 at present,” said Bui Quang Anh. :tiphat: |
