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.

According to an announcement on the company’s website, Trader Joe’s is recalling Organic Acai Bowls “out of an abundance of caution,” citing that the bowls “may contain foreign material (plastic).”

The popular item, which contains a base of acai puree mixed with strawberries, blueberries, and bananas, and topped with a granola and coconut mixture that includes chia and flax seeds and quinoa flakes, can be found in Trader Joe’s freezer section.
