Probably, but id just watch that it doesnt get too hot... And you can stick it in the oven for a bit to make sure there's nothing harmful on it. doubt there would be but its better to be safe than sorry
And give it a good scrub clean first. Any temp above 80c for about 30 mins+ should do it, then leave in the oven to cool down (a good few hours), then straight into viv. In the warm end it still shouldn't get too hot, as any stat that i'm assuming you're using will stop it from overheating.
