RXBar is recalling a wide variety of its protein bars.
The bars– which are heavily marketed as containing all natural ingredients — may contain peanuts not declared in the ingredients list.
That could trigger a life-threatening reaction in consumers who are allergic to peanuts.
The company says the peanuts came from an ingredient supplied by a third party.
RXBar has changed suppliers for that undisclosed ingredient.
Affected bars do contain a warning on the wrapper indicating they were manufactured in a facility that also processes peanuts.
The recalled products are safe to eat for people who are not allergic to peanuts.
