If you’ve got some gummy candies in your treat cupboard, better check the bags for pieces of metal.

Mars Wrigley Canada says there may be a very thin metal strand embedded in certain bags of Skittles Gummies, Starburst Gummies and Life Savers Gummies.

The strand may even be found loose in the bag.

The full recall includes:

STARBURST Gummies Original
STARBURST Gummies Sours
STARBURST Gummies Sour Berries
LIFE SAVERS Gummies Sours
SKITTLES Gummies Original
SKITTLES Gummies Wild Berries

Bag sizes vary from 57g to 280g and were sold across North America

It’s suggested to just throw the candy out.
