Avian flu is once more upon us. Between December and January every year, winter birds migrate to the south and Taiwan is a major destination for these birds. If local poultry farms do not install netting and implement disease prevention and hygiene measures, birds that become infected with H5-type avian flu will infect others, as they are reared together, and the virus might spread rapidly to other poultry farms. An outbreak would cause considerable financial losses for poultry farmers.
Therefore, it is of the utmost importance that proper tests are carried out and quarantine measures are taken once infection is detected. If an actual avian flu outbreak occurs, all the birds in the farm need to be destroyed and neighboring farms notified of the need to sterilize their premises.
In Taiwan, viruses like these are an annual occurrence and, although the Bureau of Animal and Plant Health Inspection and Quarantine has set up a standard operating procedure for handling bird flu, local authorities around the country need to be reminded of the need to carry out prevention drills in advance. Otherwise, the government risks serious financial losses and even social disturbance should an outbreak occur.
There is also the risk that highly pathogenic strains of the avian flu virus, such as the H5N2 and H5N8 strains, might combine with human flu, and such virus mutations would be very dangerous — something that doctors and public health experts are very concerned about at the moment. Once transmitted from birds to pigs and even humans, the possibility of a pandemic that threatens human lives greatly increases.
Some academics and experts have criticized the central and local governments for keeping the current status of the epidemic under wraps, and worry that warnings and testing by governments at all levels are not as responsive as they should be. As a result of the government’s inefficiency, after one particular chicken farm in Pingtung County slaughtered more than 15,000 laying hens when H5N2 was detected on Jan. 9, the virus spread to 66 bird farms in seven cities and counties across the nation within just a few days, affecting not only chickens, but also ducks and geese.
Demand for poultry and eggs is also being hit. Many poultry farmers can expect to have a hard time this year, just as the Lunar New Year is approaching. Domestic consumers are likely to be very cautious about where they buy their poultry and eggs from. Meanwhile, the Centers for Disease Control is still worried about the possibility of bird-to-human transmission.
Ever since Taipei Mayor Ko Wen-je (柯文哲) took office last month, the physician-turned-mayor has applied an “ECMO” (extra-corporeal membrane oxygenation) standard operating procedure to city affairs, and the efficiency with which he has gone about his job has not gone unnoticed. In the face of avian flu, which almost always hits the nation come winter, competent authorities from the Bureau of Animal and Plant Health Inspection and Quarantine to the Council of Agriculture should assist local governments in carrying out prevention drills according to standard operating procedure before winter arrives, and conduct random testing at large bird farms. Once the H5 virus is found, all birds at affected farms have to be slaughtered.
By following the standard operating procedure for handling avian flu, including regular sterilization at bird farms, prompt testing and the destruction of all poultry at affected farms, there will be no need for a cover-up. This will prevent a disaster and assuage the concerns of the public.

Late last month, Beijing introduced changes to school curricula in the Inner Mongolia Autonomous Region, requiring certain subjects to be taught in Mandarin rather than Mongolian. What is Chinese President Xi Jinping (習近平) seeking to gain from sending this message of pernicious intent? It is possible that he is attempting cultural genocide in Inner Mongolia, but does Xi also have the same plan for the democratic, independent nation of Mongolia? The controversy emerged with the announcement by the Inner Mongolia Education Bureau on Aug. 26 that first-grade elementary-school and junior-high students would in certain subjects start learning with Chinese-language textbooks, as
There are worrying signs that China is on the brink of a major food shortage, which might trigger a strategic contest over food security and push Chinese President Xi Jinping (習近平), already under intense pressure, toward drastic measures, potentially spelling trouble for Taiwan and the rest of the world. China has encountered a perfect storm of disasters this year. On top of disruption due to the COVID-19 pandemic, torrential rains have caused catastrophic flooding in the Yangtze River basin, China’s largest agricultural region. Floodwaters are estimated to have already destroyed the crops on 6 million hectares of farmland. The situation has been
The restructuring of supply chains, particularly in the semiconductor industry, was an essential part of discussions last week between Taiwan and a US delegation led by US Undersecretary of State for Economic Growth, Energy and the Environment Keith Krach. It took precedent over the highly anticipated subject of bilateral trade partnerships, and Taiwan Semiconductor Manufacturing Co (TSMC) founder Morris Chang’s (張忠謀) appearance on Friday at a dinner hosted by President Tsai Ing-wen (蔡英文) for Krach was a subtle indicator of this. Chang was in photographs posted by Tsai on Facebook after the dinner, but no details about their discussions were disclosed. With
On Sept. 8, at the high-profile Ketagalan security forum, President Tsai Ing-wen (蔡英文) urged countries to deal with the China challenge. She said: “It is time for like-minded countries, and democratic friends in the Indo-Pacific region and beyond, to discuss a framework to generate sustained and concerted efforts to maintain a strategic order that deters unilateral aggressive actions.” The “Taiwan model” to deal with the COVID-19 pandemic provides an alternative to China’s authoritarian way of handling it. Taiwan’s response to the health crisis has made it evident that countries across the world have much to learn from Taiwan’s best practices and if
