Spread of bird flu raises concerns over egg prices

Updated 5 hours ago

In Japan, bird flu is spreading among poultry farms, raising concerns within the Ministry of Agriculture in particular, which fears it could contribute to a sharp rise in egg prices.

Nearly 5 million chickens were slaughtered this month on 26 farms in five departments. The price of eggs has increased by about 15% since the beginning of the year.

Data from the Agriculture Ministry shows that the number of chickens slaughtered has surpassed the January 2023 total, already a monthly record.

The bird flu season typically lasts from fall to spring. The fastest spread occurred in 2022, with the current season taking second place.

The Agriculture Ministry decided at a meeting Wednesday to set up a task force in the northern prefecture of Iwate following the latest outbreaks at two farms.

Agriculture Minister Eto Taku said: "There is no indication that the outbreak will stop. The numbers could reach their highest level ever, given the deteriorating situation."

Ministry officials say consumers are likely feeling the impact of the situation, and some industry players attribute the spike in egg prices to a lack of supply.

Avian Flu Spread in Japan Leads to Culling of 5 Million Birds in January
Society Economy Environment Feb 3, 2025
A rapid rise in avian influenza outbreaks in January led to the culling of more than 5 million birds during the month, bringing the total for the season to 8.1 million. Egg prices are slowly rising.​

Since the beginning of 2025, avian influenza has been spreading rapidly throughout Japan. The situation has reached a level of serious concern, with 5.4 million chickens and other birds culled in January alone.

According to the Ministry of Agriculture, Forestry, and Fisheries, there have been 43 avian flu outbreaks during this season (FY 2024) as of January 24, second only to FY 2022, which is the highest number ever recorded. However, in terms of the number of birds culled, January 2025 outpaces January 2023, when 4.6 million birds in total were culled.

As of January 22, MAFF had set up local task forces in Chiba, Aichi, and Iwate Prefectures to bolster efforts to counter the spread of infection. Chiba Prefecture had the largest number of egg-laying hens in Japan, at 11.2 million (as of 2024), of which around 2.5 million have been culled (as of January 24).​...

Season's 1st Bird Flu Infection in Japan Confirmed in Hokkaido


Sapporo, Oct. 22 (Jiji Press)--The Hokkaido government in northern Japan on Wednesday reported the first case of infection with highly pathogenic avian influenza confirmed at a poultry farm in the country this season.

At the farm in the town of Shiraoi where the case was found, the Hokkaido government started to kill and dispose of some 459,000 laying hens, placing a ban on the transportation of 620,000 hens at four poultry farms within 10 kilometers from the farm in question.

The central government convened a meeting of related ministers in Tokyo on Wednesday morning to ensure close cooperation among government agencies in dealing with the situation.

"This is the sixth consecutive season of an outbreak. Every season, (the disease) goes into full swing from around this time," Chief Cabinet Secretary Minoru Kihara said, emphasizing the need for vigilance.

Ahead of the meeting, agriculture minister Norikazu Suzuki told his ministry's disease control headquarters, "We're in a situation in which further infection cases may happen anywhere in the country."
