my niece and nephew had hotdogs yesterday and i have craved them since!
i just read this...
Two reasons why 'they say' not to eat hotdogs. First of all, they once had a lot of nitrates (they still do, but less) which isn't good for fetus and second because all packaged meats can get contaminated with listeria at the packing place.
Nitrates: occasional hot dog is not an issue. There are FAR FEWER nitrates in today's shelf meats than in the past.
Listeria: heat the hot dog until it is piping hot throughout. That will kill any listeria contamination. The same goes for any meat you get at a deli. If you can't heat it, don't get it.
Finally, if you are having any problems with high blood pressure, skip all the shelf, packaged and deli meats because they are high in salt.
