BALTIMORE (WJZ)– A Boulder, Colo.-based manufacturer of organic nut butter products has issued a recall due to a possible salmonella contamination.

Justin’s Nut Butter has recalled its organic peanut butter cups, organic milk chocolate peanut butter cups and organic dark chocolate peanut butter cups.

Giant and Martin’s grocery chains that sold the products have now pulled them from their shelves and ask customers to discard the items. Giant and Martin’s say they will give customers with receipts a full refund.

For more information, customers can call Justin’s at 303-449-9559.
