Gyeonggi-do bans bringing chickens and ducks from Jeonbuk… Promotion of AI quarantine measuresWhen the presence of highly pathogenic avian influenza (AI) was confirmed at a laying hen farm in Sangju, Gyeongsangbuk-do, a temporary suspension of the movement was ordered in five areas, including Gyeongbuk.
AI’s Central Accident Control Office announced on Day 2 that a close inspection of brood hens in Sangju, reported on Day 1, resulted in a confirmation of the highly pathogenic H5N8-type AI. .
The broadcast period is until 9pm on the 3rd in Gyeongbuk, Chungnam, Chungbuk and Sejong on the 3rd, and until 9pm on the same day in Gangwon.
The targets are poultry farms, livestock facilities (slaughterhouses, feed mills, etc.) and livestock vehicles.
The farm in Sangju, where the highly pathogenic avian influenza occurred, reported suspicious symptoms such as increased mortality of laying hens, decreased laying rate and reduced feed intake the day before and reported this to quarantine authorities.
The type of H5N8 released this time is the same type as the Duck Farm in Jeongeup, Jeollabuk-do, which was confirmed on the 28th of last month, and all highly pathogenic AIs detected in wild birds so far were of this type.
Vice Minister of Agriculture and Food Lee Jae-wook said: “There is a small river that wild birds can inhabit around the outbreak farm, and wild birds were also observed.” Radio waves are believed to have been produced. “
Vice Minister Lee said, “We are conducting an epidemiological investigation with several routes in mind,” as to whether there is a connection between the Jeongeup and Sangju farms.
Heavy water bone kills 188,000 chickens from highly pathogenic AI farms, 120,000 quail from farm-owned farms, and 251,000 chickens from three poultry farms within a 3 km radius. The quarantine zone was established and movement was restricted for 30 days to 13 poultry farms within the quarantine zone.

Furthermore, the heavy water supply also reinforced the national quarantine, as there is great concern that the disease will continue to spread.
In the case of 11 dense rearing complexes of domestic breeder hens, the number of times of disinfection of the access roads entering the rearing complex increased from one to more than two per day, while the thorough disinfection of vehicles and people inside and outside the checkpoints of each complex.
In addition, the poultry farm in the dense breeding complex carried out the mortality inspection once a week, which was carried out every two weeks, and the construction of the quicklime belt around the access road to the poultry farm and barn also it was held once a week.
Additionally, telephone surveillance of laying hen farms across the country was strengthened from biweekly to once a week, and AI testing was increased from once a month to twice a month for laying hen farms in Gyeongbuk and Jeonbuk, where highly pathogenic AI occurred in poultry farms.
Furthermore, to avoid the entry of contaminants into the laying hen farm and cross-contamination between farms, the egg transport vehicle (edible eggs) was ordered to visit only one farm per day.
Also, if the egg dish is reused, it is used disposable as much as the contaminant can spread, and the plywood and pallets must be fully sterilized and used separately for each farm.
Management was also strengthened to block horizontal spread between farms in advance.
First, a poultry farm that has been confirmed to have visited a farm with AI presence is unable to move for 14 days, and a thorough clinical observation and detailed examination is also performed to determine if the poultry are infected with AI. .
Additionally, vehicles visiting AI-prone farms cannot be moved for 7 days from the last visit, and vehicles must be thoroughly disinfected and washed.
The edible egg grading and packing facility operated by the farm must operate with entrances, fences, and disinfection facilities separate from the rearing facility, and open-air eggs are prohibited.
Vehicles transporting edible eggs cannot access the collection facility within the farm, and if unavoidable, it is only possible to enter the facility after prior notification and stage 3 disinfection.

“Highly pathogenic AI antigens are continuously detected in wild birds across the country, and the outbreak is increasing rapidly around the world, including Europe and Japan,” said Vice Minister Lee. “Considering that domestic migratory birds continue to increase until January next year, in any part of the country It was a very serious situation in which a highly pathogenic AI could occur,” he worried.
He emphasized, “Even if the farmhouse is 99% quarantined, the virus penetrates only 1% of the weak link, so be sure to practice the 4th stage of disinfection with the awareness that 100% quarantine measures must be taken. “.
