Here is the link to the FDA website about the recall our vet sent out a notice that they were advised to update their caution letters to clients this week to include the Blue Buffalo as well as the Kingdom Treats being sold via Costco. We asked our vet if we should throw out the treats we have and she said no, as it wasn't one of the brands on their list. I have no idea if there is a difference between the USA standards and the Canadian standards with regards to food for pets, I just wanted to give everyone a heads up as we were notified by our vet as well as other's in our neighborhood that have different vets than us.
Here is the FDA notice:
