Costco is recalling a frozen fruit mix after concerns about a possible listeria contamination.

The voluntary recall is for Rader Farms Fresh Start smoothie blend, which was sold at Costco stores throughout Western Canada.

The Canadian Food Inspection Agency says the kale and spinach in the mix may contain listeria.

No one has reported getting sick from the product.

The CFIA has posted the affected batch numbers on its website.

The agency suggests you either throw it out or return it to the store.
