Most meats are a no carb deal - I am no expert in this please note that. I know Jersey Girl can probably give ya the best advice!
But, I was using Johnsville Sausages and they only had I believe 1 carb for 2 oz and I usually eat about 4 oz... they aren't indivdual sausages though. There are definitley lower carb items. I know it's important to read the label as well and avoid foods with added sugars and things that are not allowed on Atkins, even if it meets the carb count list.
My Atkins book says foods with 3 carbs or less per serving are ok (as long as in the range of acceptable foods) even if not listed specifically in the book. So my advice would be to find a different brand with less carbs.
