No you won't.
If you have an expertise, don't hesitate to speak up, that's what the forum is all about, sharing our knowledge. The sausage forum could use a little more traffic, so many you can help the sausage guys
Well, it doesn't take much to get me to wax poetic over sausage, as you can tell. I try and cut myself off, as while I don't understand this, it seems not everyone shares my awe of a well made sausage, with great ingredients, cooked properly. Let me know if I bore people!

Botulism spores can survive past the boiling point. You never want to hold a good pork sausage anywhere near that. It will render the fat out, leaving you with a meat that resembles cooked cardboard in texture. You never want to smoke a "fresh" sausage, cold or hot. People do it all the time, there's only about 30 cases of botulism a year in the US (usually from home canning or smoking), so you've got the odds deeply on your side that nothing will happen. Me? I figure just that once will ruin my day (and the next couple of thousands days to follow).
First of all. Great info. Now the questions:
OK. So I've got a sausage with botulism spores. I'm one of the 30. Are you saying nothing can kill them? Hot smoking or flaming hot grill cause we're never taking the sausage to 212*? Or is there simply a difference between slow and quick cooking? I know a lot of us hot smoke or grill fresh sausage. If this were really a concern, wouldn't the FDA require all sausage to be cured? Please don't tell me it's simply a #'s game.
It's all about the holding time at temps under 140. Grilling, or smoke roasting, it's cooked fairly quickly. That environment is not conducive to the bacteria multiplying and releasing its deadly toxin, so even though you got the sausage with the spore, you didn't give it a chance to grow. You eat the spore, it passes through, nothing bad happens. It's the slow smoking, in an oxygen deprived environment, that allows botulism to grow.
Depending on what type of sausage it is, I try for a 4-8 hour smoke. An hour or so at 120 to dry the casings (develops a "pellicle" that the smoke will stick to), then slowly raise the ambient to no more than 165. As I was saying, fat will render at higher temps, and that's exactly what you're trying to prevent. I look on a sausage as fat held in an emulsion of meat
You're right though, it's partially a numbers game. Also, botulism tends to be present on veggies and produce, not meat (it comes from dirt basically). However, lots of fresh ingredients, like cilantro or parsley, gets put into good sausages you can buy at the markets these days. Odds are pretty stacked in your favor you'll never meet a spore. It's just that one time...
So to distill that long post, quick cook and it doesn't have the chance to grow. However, slow smoking is the perfect environment.
