“We want to acknowledge some feedback received regarding our Juneteenth celebration,” Pezzuto said in his letter obtained by The North Carolina Beat. “Although our intent was to celebrate this nationally recognized day, some of you voiced your concerns regarding the associated food choices.”

Chickens were often the only animals enslaved people were allowed to raise for themselves. Like many racist stereotypes, it’s more rooted in the 20th Century than slavery or early American history. There used to be some chain restaurants - notably Coon Chicken Inn - that used racist caricatures to sell their fried chicken, so it’s basically an advertising meme.
Pretty much the same thing for watermelon. It was an easy to grow fruit that freed slaves used as a source of income and they caricatured it in racist media.
