The problem with deli meats is that they are processed and cooked, making them great breading grounds for certain types of bad bacteria.
Jerky is dehydrated and does not have the same qualities that bacteria desire (moisture, accessible nutrients - the salt makes it inhospitable for bacteria).
It still might be a good idea to check with your doc/nutritionist, but jerky should be ok. Make sure to store it in a cool, dry place once opened (zip top bag or the like)... that is if you have any left over
