Land shortage hampers culling in Japan amid bird flu outbreak
11 hours ago

NHK has learned that mass culling of chickens amid a record bird flu outbreak in Japan has been hampered by a shortage of suitable land in 16 of the country's 47 prefectures.

Over 17 million chickens have been culled this season because of the bird flu, the highest number ever. About 9 percent of hens kept for their eggs in Japan have been disposed of.

Local governments and poultry farms usually bury the culled birds to prevent the spread of the virus.

NHK contacted 26 prefectures that reported outbreaks this season and learned that 16 were having problems...

Bird Flu Is So Bad That Japan’s Running Out of Land to Bury Chickens


Jasmine Ng and Shoko Oda, Bloomberg News
(Bloomberg) -- Japan’s worst-ever bird flu outbreak has decimated its poultry flocks and sent egg prices soaring. Now there’s a lack of space to bury dead chickens.

More than 17 million birds have been killed nationwide this season. The disposal of carcasses must be done properly to prevent spreading the virus or contaminating water supplies....

Japan’s case highlights the need for countries to review how they deal with avian influenza, especially as record-breaking death tolls due to the virus are becoming a norm around the world. While outbreaks have occurred mainly in Europe, the US and Asia, the disease has spread further to South America in recent months, with Argentina, Uruguay and Bolivia reporting their first cases.
..... Some regions are burning the dead chickens if they can get hold of incineration facilities.

The bird flu epidemic in Japan continues to spread, and the cumulative number of poultry that needs to be culled so far exceeds 17 million

According to a report from the Ministry of Agriculture, Forestry and Fisheries of Japan on the 5th, a highly pathogenic H5N1 bird flu outbreak occurred on a farm in Chitose City, Hokkaido. This is the 83rd case reported in Japan for the current bird flu season.

The Ministry of Agriculture, Forestry and Fisheries reported that on the 3rd of this month, a farm in Chitose City, Hokkaido reported poultry suspected to be infected with bird flu, and the animal health research department conducted genetic analysis on the samples of these poultry. The results showed that the infection was highly pathogenic H5N1 avian influenza virus. About 350,000 laying hens on the farm will be culled, along with about 40,000 on another farm related to it in the same city.

The epidemic season of bird flu in Japan is usually from autumn and winter to spring of the following year. A farm in Okayama Prefecture reported the first bird flu outbreak in Japan this bird flu season at the end of October 2022. Since then, the epidemic has continued to spread. So far, the cumulative number of poultry that needs to be culled in Japan exceeds 17 million.

Bird Flu Suspected in Japan's Saga


Tokyo, Nov. 24 (Jiji Press)--A suspected case of bird flu infection has occurred in Kashima, Saga Prefecture, southwestern Japan, the Japanese government said Friday.
If confirmed, it will be the country's first case of bird flu in poultry this season.

Prime Minister Fumio Kishida ordered officials to take measures to prevent the spread of infection, collect information and provide accurate information to the public.
Last year, the first bird flu case was confirmed on Oct. 28. The disease has spread to 26 prefectures across the country, leaving a record 17.71 million birds culled. The supply shortage of chicken eggs also became serious, causing egg prices to soar.
