Korea Joongang Daily reports that this is the first investigation under the new leadership of former economic professor and civic activist Kim Sang-jo, who was confirmed as head of the FTC last week by President Moon Jae-in.

Among the top three chicken franchises, Kyochon and BHC announced that they will be lowering prices while BBQ has raised prices despite public sentiment.

Chicken and egg prices have been rising since a bird flu epidemic hit several farms across the country, including on Jeju island, this month.

The newest outbreak happened before the wounds from the bird flu crisis in the first two months of this year healed. BBQ is also accused of forcing franchisees to pay for ads.
