KFC commented that the food item appeared to be natural and harmless and that they were reaching out to the customer.

A KFC spokesperson told My London: “Hands up. This doesn’t look great, but it looks like a natural part of the chicken to us.

“This sometimes happens when dealing with fresh chicken. It’s harmless but it goes without saying it’s not appealing and shouldn’t be there, so we’re reaching out to the customer to make things right.”

The Mirror has contacted KFC for further comment.
