hey guys i am a first time mom and everyone says thats its not safe to eat raw hots dogs during your pregnancy, have any of you heard this before?

Yes - the issue is listeria, a bacteria that can be found in hot dogs, deli meats, and even prewashed, bagged salad.  It dies when it's heated, so as long as you heat the meat/hot dog until it's steaming (in the microwave, etc), you've killed it.  As for bagged salad, just buy fresh head lettuce and wash it.

The issue with hot dogs is that no one knows what's in them - what parts of the cow, as well as what artificial growth hormones, pesticides, etc.  If you can't cut them out of your diet, at least cut down on them and buy the varieties that have the fewest ingredients and preservatives as possible (organic, if you can).  There have been studies showing that pregnant women who consume large amounts of hot dogs have babies with issues, so this would be a good diet change to tackle.
