"Very, very unfortunate that this happened," said spokesperson Shannon Denny. "We apologize to our consumers for this."
The words are part of a promotion for Vitamin Water where random French and English words are printed on the caps, she said.
"Retard" is a French word meaning late.
"The chances were so slim through this random process," said Denny adding that not anticipating the potential word pairings was a mistake.
"The promotion has been cancelled," Denny said. "We are stopping production of all of the bottles using those caps with words. And any caps we have within our inventory are being destroyed."
