Trader Joe's is telling its customers to throw away or return the grocery store chain's organic acai bowls because they possibly contain plastic. The Monrovia, California-headquartered company announced the recall on Feb. 14 "out of an abundance of caution." Trader Joe's said the product "may contain foreign material (plastic)."

Acai’s dark purple berries are from a palm tree found throughout South America and are touted as an antioxidant-rich food source that some nutritionists believe can protect cells from damage, according to WebMD. Proponents say the berries are richer in antioxidants than cranberry, raspberry, blackberry, strawberry or blueberries.
