“Out of an abundance of caution, please discard any Trader Joe’s Organic Acai Bowls, as the product may contain foreign material (plastic), or return them to your neighborhood Trader Joe’s store for a full refund,” the notice on Trader Joe’s website states. No illnesses or injuries have been reported to date, according to Real Simple.

The popular breakfast item was recalled last week due to possible plastic contamination. The grocery chain did not say if the product had made anyone ill.
