Dog Food Dying

Does anyone know where I can have dog food tested for the substance that sparked the pet food recall?
I would like to know if there is a place in Montreal where I can take a sample of the food and have it tested because my dog died recently of food poisoning.
i’m not sure, but you can call the manufacturer and tell them your dog died recently of food poisoning. did you give your vet the dog food information? they may be able to guide you to where you need to go.
