Letters | Hong Kong must act now to prevent African swine fever virus from crossing into local farms
- The virus may not harm humans, but could be devastating to the local pork industry and wild pig population
- Informal imports of pork products are a major concern, and early reporting of suspected cases will be essential
While the African swine fever virus does not cause disease in humans, it results in high mortality in affected pigs, and those losses will lead to increased pork prices. The latter is a major concern for mainland China, particularly in the lead up to the Lunar New Year, when there will be increased demand for pork and therefore increased trade, which is likely to further speed up the spread of the virus around the country and to neighbouring areas.
We believe that urgent steps must be taken to protect the local domestic and wild pig population from the introduction of the African swine fever virus. A key aspect of this will be to ensure early reporting of any suspected cases by local farmers and pigs imported only from infection-free farms in the mainland.
Measures like strengthened biosecurity and regular on-site inspections have to be implemented. Furthermore, there must not be any pig swill feeding allowed on Hong Kong pig farms, and each farm should be encouraged to enhance biosecurity.
A major concern is the informal import of pork and pork products into Hong Kong, and the effectiveness of measures to minimise these need to be improved. The severity of the situation is currently seemingly being underestimated by policymakers, largely because it is not a disease affecting humans.
