That depends. Were they refrigerated the whole time you had them? Did they get warm for any reason? If you cook them thoroughly, then they should be fine. I wouldn't eat them without cooking them (I'm assuming they are pre-cooked, as most hot dogs are sold, not raw, as most sausages are sold). I worked in the food manufacturing business for years. The expiration date is an 'absolutely still healthy, tasty, and wholesome' date for food, not a 'toss me or you'll die' date, as some people might have you believe. And, for all products, you should perfectly safe eating the food up to, and usually a few days beyond the expiration date. Some foods are still perfectly fine well beyond that date (Recent testing of C-rations that were canned for use during World War II showed that they were still in very good shape, and their vitamin content was actually higher than originally reported), while others are not (one local dairy is known for milk that expires within a day or two of their expiration dates), it really depends on the producer and the food's handling since it was made. Sometimes food isn't stored or transported correctly, and it gets too hot (this usually doesn't matter with canned food, but it does for most other types). In the food industry, this is known as heat damage. The problem isn't that the food is actually damaged (though it can be, in the case of frozen foods), usually it means that it was not stored according to the manufacturers directions, and something happened. With ice cream, it can change texture, often becoming gummy; with frozen dinners, they can build up moisture which crystallizes and makes the food soggy when it's cooked; with chocolate, cocoa butter will separate, giving it a waxy, white covering, etc. With hot dogs and other meats, if they get warm for too long, bacteria that was mostly killed during cooking can start to grow again. You can get very sick with several types of food poisoning, which can be a painful or possibly deadly experience (with e coli). I've had food poisoning twice, both from fast food restaurants, not from eating at the food companies I worked for, and it is extremely uncomfortable, sometimes very painful. Hence, my questions: were they refrigerated, did they sit out? And my suggestion: Only if you cook them thoroughly, because this kills the bacteria. Would I eat them? Sure! I'd boil the poo out of them or microwave them completely in a closed container, to make sure they're thoroughly cooked, though!
