Swill banned for pigs, linked to disease
CHINA’S agriculture ministry said yesterday that it would ban the feeding of kitchen waste to pigs after linking the practice to the majority of the early cases of African swine fever.
The statement from the Ministry of Agriculture and Rural Affairs is the government’s first comment on how the deadly disease has spread in the world’s top pork producer.
China has reported more than 40 outbreaks of the highly contagious disease since early August, with farms across 12 provincial regions already infected.
It does not affect humans. China has not yet said how the disease first entered the country but the ministry found 62 percent of the first 21 outbreaks were related to the feeding of kitchen waste, a statement published on the ministry’s website said.
“These outbreaks were mostly located in urban-rural boundaries, and were particularly evident in several cases in early September in Anhui Province,” the statement said.
Anhui is an eastern province, whose capital Hefei is located about 415 kilometers west of Shanghai.
The virus was also detected in kitchen waste fed to pigs on a farm in the Inner Mongolia Autonomous Region, it added.
“After the provinces with outbreaks and neighboring provinces completely banned feeding of kitchen waste to pigs, the epidemic was greatly reduced, which fully demonstrates the importance of completely prohibiting the feeding of waste,” the statement said.
Kitchen waste or swill is widely used in China to feed hogs, particularly by small farmers, as it is cheaper than manufactured pig feed.
Regulations require that the swill must be heated to a certain temperature before being consumed but industry experts say that step is often skipped.
The ministry also said in the statement that it will set up a registration system for vehicles transporting live hogs, poultry and other livestock to control the spread of the disease better.
The long distance transport of live hogs has been the main channel for transmitting African swine fever across different regions, it said.
Vehicles transporting pigs and other animals will also no longer be allowed to use the “green channel” for priority on roads that is normally permitted for the trucking of fresh produce, the ministry added.
It called for more slaughtering closer to farms and the use of refrigerated transportation to better manage the supply of livestock across different regions.
On Tuesday, authorities lifted quarantine in an eastern city.
Laboratory tests and on-site assessment by local authorities showed the epidemic had been eliminated in the city of Tongling, Anhui Province, the agriculture ministry said.
No new cases had been found during the past six weeks, with immediate actions taken to block, cull and disinfect the affected pigs after the outbreak.
