The Agriculture Ministry confirmed an outbreak of the highly pathogenic H5N6 bird flu at a duck farm in Yeongam, South Jeolla Province, Monday.
This is the fourth confirmation of highly pathogenic bird flu this season.
The government on Monday culled some 76,000 ducks at five farms located within a 3 kilometer radius of the original farm where the highly pathogenic strain of bird flu was detected. Since Monday midnight, a transportation ban was issued on all livestock industry persons across Daejeon, Gwangju, Sejong, South Chungcheong and South and North Jeolla provinces.
Yeongam is about 380 kilometers south of Seoul. The rural region is home to one of Korea’s biggest duck farms. Together with the adjacent Naju, the area accounted for 52 percent of the entire domestic duck produce in the third quarter of this year.
The farm where the virus was detected is one that supplies breeding ducks to other farms. About 10 farms were found to have taken ducklings from this farm in recent month. The trucks that transported the baby ducks made visits to some 30 other farms over the month, raising the possibility of secondary infection.

A reassortant H5N6 avian flu virus detected in three Asian nations over the past few weeks has been confirmed in an outbreak in the Netherlands.
In other developments, South Korea—one of the countries that has already reported outbreaks from the H5N6 reassortant this season—reported another at a duck farm. And Cambodia reported an H5N1 avian flu outbreak in poultry, its first in nearly a year.
The outbreak in the Netherlands was first reported on Dec 8, and government officials had said initial tests from the duck farm near the city of Dronten was likely a highly pathogenic strain. In a notification yesterday from the World Organization for Animal Health (OIE), the country’s economic affairs ministry said the outbreak began on Dec 7 at a fattening-duck farm near the town of Biddinghuizen.
The virus killed 40 of 15,985 birds, and the surviving ducks were culled to curb the spread of the virus. Tests revealed the H5N6 subtype is a reassortment linked to H5N8 and not the Asian zoonotic H5N6.
Animal health authorities have established surveillance and protection zones around the farm. Screening at four farms in the 3-kilometer (km) surveillance zone was negative for H5N6.
A report from the country’s Wageningen Bioveterinary Research Institute, translated and posted by the infectious disease news blog Avian Flu Diary (AFD), said the farm was one of the first to be hit by H5N8 last season. The institute said initial tests suggest that it is not related to the zoonotic H5N6 strain. The virus’ H5 is related to the highly pathogenic H5N8 found in the Netherlands in 2016, and the N6 is related to low-pathogenic viruses previously found in wild birds in Europe.
The Netherlands is the fifth country to report the H5N6 reassortant, which is similar to a virus fist identified in Greece during last winter’s extensive H5N8 outbreaks that struck Europe and other parts of the world. The virus is a reassortant of highly pathogenic H5N8 and endemic Eurasian viruses.
In late November, South Korea reported its first outbreak involving the H5N6 reassortant, and the following day, Japan reported a detection in samples from a dead wild swan. A few days later, preliminary tests in Taiwan identified the same reassortant in a sample from a wild bird found dead in a national park.
In a related development, South Korea’s agriculture ministry today confirmed another H5N6 outbreak, this time at a commercial duck farm in the city of Yeongam in North Jeolla province, the country’s Yonhap News reported. The ministry said 76,000 ducks were slaughtered at five duck farms within a 3-km radius of the outbreak site to control the spread of the virus.
Officials said the virus is probably highly pathogenic, but more test results to further characterize it are expected.
Elsewhere, Cambodia’s agriculture ministry reported a highly pathogenic H5N1 outbreak at a local chicken farm in Kampong Chang province, according to a Dec 9 notice from the OIE.
The event began on Nov 22, killing nearly all of the 1,763 chickens at the location. The farm’s owner reported the sick and dead birds to provincial authorities on Nov 28. The surviving 24 birds were culled. So far the source of the virus isn’t known. Kampong Cham is in south central Cambodia.
The country’s previous H5N1 outbreak occurred in January.

Hundreds of fish have been found dead in Rio Guaporé, Vila Bela da Santíssima Trindade, 562 km from Cuiabá. The concern is that the water that is consumed by the inhabitants of the communities located near the river is contaminated. Many also have fishing as a means of survival.
The deaths were recorded in situ by professor Ivan da Silva Costa, who works on the public network that municipality and specializes in environmental sciences. Among the species are painted Peacock bass and catfish.
“Our concern is for the families of these fish feeding Riverside and, if it is some kind of contamination of the water coming from the camp of Serra da edge or pesticides of neighboring farms, all are at risk,” he said.
According to the municipal Secretary of Environment, Luciano Prophet of the cross, a primary analysis was made by the Secretariat and the suspected water contamination has been ruled out. However, other more specific analysis must be made by the company Mato-grossense, research assistance and Rural Extension (Empaer).
The Secretary explained that the fish may have died because of waste products that fall in the river and go into decay, hurting the oxygenation of the water.
According to him, the recovery of riparian vegetation will prevent this organic material down the river. The Secretary reported that awaits a project announced by the State Government for the recovery of the banks of rivers throughout the State, including the Rio Guaporé.

Since 5 days ago to this day is already 100 tons fish dead tilapia in Floating Net Keramba (KJA) Lake Maninjau, Agam, West Sumatra. The demise of fish in Lake Maninjau result much pollution that occurs at the bottom of the Lake.
“The whole keramba fish in this Lake the fish are dead, there are 18 thousand keramba, but we’ve been asked to fish communities and entrepreneurs to stop temporarily, until it is really water on Lake Maninjau is clean,” said the Fisheries Agency and food security (DPKP) Kabupaten Agam, Hemanto to the Okezone,
The cause of death of these fish because the content is already polluted Lake Maninjau ranging from household waste, agriculture, fish feed, fish die before it is left to the base of the Lake settles.

People on a popular Lee County beach had to avoid dead fish. Florida Fish and Wildlife says toxic red algae is to blame for all the dead fish that washed up on Sanibel after they detected high levels of red tide along the Lee County coastline.
“It smells bad and the water is very murky,” said Pam Boardman, who walked along the beach Tuesday. “Lots of dead sea life,” she added.
People who visited the beach set up their umbrellas and chairs away from the dead fish.
“I’ve been coughing and sneezing a lot,” said Julie Stevenson, while she was on the beach.
Some happy they brought some medication with them along with their sunscreen.
“I actually took a Claritin,” said Donna Schettina, after a few coughs. “We aren’t going to stay as long as we would like,” she added.
Florida Fish and Wildlife recommends people with respiratory problems to steer clear of toxic red tide.
“People with asthma shouldn’t come,” said Schettina. “I have children who have it and I wouldn’t bring them or my grandchildren,” she added.
Florida Fish and Wildlife says it’s safe to swim but to avoid areas with a lot of dead fish because of the high levels of bacteria. FWC will test the waters again on Friday.

For the past two days, thousands of dead fish have been washed ashore along the coast at Besant Nagar or found floating in the estuary of the Adyar near the broken bridge. Fishermen of Urur Kuppam, who have been removing fish from the water and throwing them on the shore, wonder whether the deaths are due to lack of dissolved oxygen in water.
“This is the breeding season for fish and they enter the estuary in large numbers. As the rainwater has pushed a lot of sludge towards the sea, the water at that point is polluted leading to these deaths. It happens almost every year. But this year, it looks like thousands of fish are dead. Some of them have turned black. Some are quite big in size, which is a sad thing,” said Karunakaran of Urur Kuppam.
Fishermen have collected some of them and salted them to be used as dry fish (Karuvaadu).
G. Sundarrajan of NGO Poovulagu Nanbargal said the loss of fish at this time would mean a reduction in production in the area next year.
“Already fish production is on a downward trend due to acidification of the oceans. The government needs to ensure that sewage treatment plants function well even during rains. Untreated sewage might have caused the deaths,” he said.

Last Monday, Jacques Peter Smart walked through the snow to a creek in downtown Bethel, a shallow tributary from Arthur Dull Lake that runs above ground between Sixth and Seventh avenues. Hundreds of dead fish were curled together at the bottom of the rust-colored creek bed, each small enough to fit in your hand.
“We’re looking at a bunch of dead blackfish that washed out of Dull Lake,” Smart said. “It happened over a period of three to seven days, but it kind of totally happened overnight, and we were shook by it.”
There are 500 to 1,000 fish, Smart said, and he suspects some washed farther downstream as well.
Originally from Nunapitchuk, Smart studies information technology at the University of Alaska Fairbanks’ Kuskokwim Campus. The program is a lot of work, so a few months ago, Smart and a half dozen other students started fishing the Kuskokwim together to unwind. They bait their hooks with blackfish, and they set several traps for them in Bethel’s streams and lakes.
Smart started finding dead fish in his trap near Dull Lake about two or three weeks ago. Now there are hundreds and hundreds of them. He posted about the die-off on Facebook, and last week the Orutsararmiut Native Council decided to get involved.
“We haven’t seen this before,” said Mary Matthias, ONC’s environmental coordinator. “So there’s something in the water. I mean, someone’s putting something in the lake.”
Matthias said that the fish were most likely killed or disfigured by pollution. The culprit could be a chemical leak from a local business, an accidental spill, or run-of-the-mill littering.
“Within this past year I’ve seen batteries stationed right outside of the dumpster on the ground instead of getting recycled,” said Matthias. She added that discarded electronics and fuel can also have this effect on animals living in the water.
