In 2024, the laying hens industry experienced significant conflict due to efforts to improve breeding areas and regulations, including the highest number of breeding hens ever recorded. This led to exports to Vietnam being blocked due to detected salmonella and confusion in the edible egg sorting and packaging industry. After a 2018 revision of the Livestock Act, the Ministry of Agriculture, Food and Rural Affairs proposed changes to laying hen space, causing protest from farmers. The Korea Laying Hens Association sued the ministry for the retroactive application of the law without compensation, and Vietnam's strict quarantine regulations have impacted Korean laying hen exports.
