I have been making jerky for 3 years now and havent had any problems at all. I use the Nesco FD-37

Works wonderfully. This nifty and cost effective dehydrator also works great for drying pepper pods for grinding into powders. I use Hi Mountain Jerky kits, lots of wonderful flavors. I spice the mix up with my own pepper powders, mix it into the HMJ seasoning when you combine the seasoning/cure salt together.

Here is what I do...
Mix the HMJ seasoning/cure salt as directed in the kit for the amount of meat I am going to jerkify (I dont think thats really a word LOL)
Take your meat that you want to make into jerky (ground or whole muscle) and drain it of blood.
Mix the jerky cure/seasoning as suggested in the directions and sprinkle it onto the meat.
Put the meat in a tupperware container in the fridge for atleast 24 hours (for whole muscle)
Once cures, spread onto a cookie sheet lined with no stick foil and put into the oven for 90 minutes at 200 degrees This is done to
kill any and all little nastiest, making the meat safe for consumption.
Put the meat onto the trays and dehydrate for 4-8 hours (depends on how dry you like it)
Store in a tupperware bowl in the fridge.
I have never had an issue with the meat going bad on me, it usually doesnt last that long anyways. LOL
