When doing a long cook over 36 hours the meat seems to develop a foul odor. What is the best way to avoid this? Quickly blanching the meat in boiling water first?

And yes, that is the best way to avoid it. It's Lactobacillus, a harmless bacteria. It is found in cheese a lot, particularly stinky cheeses. You can find out more about it in my Why to Boil Your Sous Vide Food First article.

Lactobacillus smells really bad and from my experience it seems to be in the air in certain places. I've never run into it despite having cooked hundreds of sous vide meals now. Some people run into it almost every time they cook, and I think it's just what's in the environment of their kitchen. They probably eat more cheese than I do.

But if you run into that or if you just want to be safe so you don't run into it, you can dunk the meat in boiling water for 5 to 10 seconds before you sous vide it. This is enough time to kill anything on the outside.

But it's something if you run into issues. It primarily happens in over 24 or 30 hour cooks, but Lactobacillus can grow in the higher sous vide temperatures where the dangerous bacteria can't grow at those temperatures. So it's not bad for you. It just smells horrible.
