It has *now been found guilty as only 15% is chicken and the remaining 85% is not even good for consuming but for dogs.*
As far as I am aware, KFC doesn't sell burgers, but they sell chicken sandwiches. You must also be know that KFC does not import all of its chicken from one plant, rather KFCs in different countries source their own chicken , and sometimes the chicken is 100% locally sourced.
So in which country does KFC serve chicken sandwiches which only contain 15% chicken?
