G'day gil...
A mate of mine hitched south to north across Africa some years back.... and packing some 'biltong' was the go. When he got back he made quite a bit of it, in the manner you are doing........ It sure tasted good. A 'beef jerky' with personality !!

))
Another mate, only a year ago, copped a dose of "campylobacter" from some meat at a racecourse. He was nearly 'history'.....and we were all rapidly 'educated' in some of the bacteria that can multiply on improperly prepared food, especially meat.
Campylobacter requires a minimum of Ten Minutes at _ 180C _ to knock it over !!!!.. air drying,microwave drying etc doesn't come near this. Frying it up in oil would, though. So would grilling it, or sticking it in the oven at around 200c for a while!!
Sooo..... if you 'process' meat without ensuring that , at least, this little 'nasty' is knocked out, you could be in for a couple of weeks on a drip in hospital.... or worse.
Maybe check out with your local health dept for some more info !!!
Just some random thoughts that your 'biltong' generated.
