World Korean river runs red from blood of pigs culled amid African swine fever outbreak
Australia cancels man's visa over four kilograms of pork
A second traveller into Australia has had his visa cancelled over African swine fever concerns. A 60-year-old Vietnamese man, who arrived into Sydney with close to four kilograms of pork-filled mooncakes stowed in his luggage, was sent home for failing to declare the food, Agriculture Minister Bridget McKenzie said.It follows the deportation of a Vietnamese woman last month, who also failed to declare pork products.© 9News A Vietnamese woman had her visa cancelled for failing to declare more than 4.5 kilograms of pork last month.
As South Korea battles an outbreak of African swine fever (ASF), the destruction of some 47,000 pigs has led to the Imjin River, which runs through the demilitarised zone, turning blood red.
The strange colour is the result of the river being polluted with the blood of many of the slaughtered pigs. Heavy rains caused their blood to flow from a border burial site into a tributary of the Imjin.
South Korean authorities culled the pigs in an attempt to halt the spread of the disease, which is highly contagious and incurable, with a near-zero survival rate for infected pigs.

It is not dangerous to humans though.
Merck wins European approval for first-ever Ebola vaccine
Merck wins European approval for first-ever Ebola vaccineThe vaccine, Ervebo, is approved for individuals aged 18 years and older and has already been used under emergency guidelines to try to protect against the spread of a deadly Ebola outbreak in Democratic Republic of Congo.
Still, the contamination of South Korea's seventh-largest river has prompted concerns it could aid the spread of ASF to other at-risk animals.
However, authorities dismissed such fears, saying the culled pigs were disinfected before being slaughtered.
They also said emergency steps had been taken to prevent further pollution of the river, which was the site of a battle during the Korean War.
The pig-culling operation was carried out over the weekend. The carcasses were said to have been left inside multiple trucks at a burial site near the inter-Korean border.
A delay in the production of plastic containers used in the burial meant it could not be carried out immediately.
North Korean link
ASF was only discovered in South Korea recently, and there was speculation it arrived via pigs crossing the heavily guarded demilitarised zone (DMZ) that separates the north and south even though South Korean officers at the zone had been authorised to and have shot dead wild boars trying to cross.
Despite the precautions, South Korea reported its first ASF case on September 17, with the total now at 13. There are about 6,700 pig farms in South Korea.
Much of Asia has been affected by the outbreak, including China, Vietnam and the Philippines.
In China, where pork is a staple of the diet, 1.2 million pigs have reportedly been culled. More than 5 million are believed to have been culled in Vietnam.
Mongolia, the Philippines and Laos have also culled tens of thousands of pigs.
The virus is yet to reach Australian shores but it is having an effect on the industry here, with "over-the-hook" pork prices rising from roughly $2.50 per kilogram last year to $3.50 per kilogram this year.
