Now that's what I call a great post and just what I was looking for. So it looks like I'm pretty safe after just 2 weeks as I did use an all in one cure containing nitrite.
Interesting point about salmon the smoking temperature being allowable much higher, I have read that but I have always been even more reluctant to smoke it until the colder weather. I can see that the moisture content would be reduced by doing so at higher temperatures though.
