Those that aren't cooked are smoked. 100% of all frankfurters, wieners, hot dogs, and bologna intended for sale in the US is safe to eat cold, as long as it has been kept sufficiently cold since it was packaged. If it wasn't cooked or smoked, you can't call it by those names. The most common [pathogenic] contaminant is Listeria. This would be on the surface, so if you want to be strict about food safety, you can just drop your cold hot dogs in boiling water for a few seconds before eating them. But if you're really that concerned about food, why are you eating sausages at all?
