Taiwan is currently facing a severe outbreak of bird flu, with over 17 poultry houses infected and many more chickens dying than in previous years. The outbreak, caused by the H5N1 and H5N2 strains, has led to concerns about the health of poultry and livestock, as well as the potential for the virus to mutate due to vaccination. The situation is further complicated by the need to cull chickens, which cannot be exported if they are vaccinated or if the epidemic continues in the area. The government is considering various prevention measures, including the use of airtight water curtain houses and vaccination, but there is debate among scholars and experts about the effectiveness and safety of these measures. The situation highlights the challenges of balancing the need to protect poultry and prevent the spread of bird flu with the need to ensure the safety and exportability of poultry products.
