it's probably ok. sub 40F salted & nitrited industrial pork likely reduced microbial metabolism to near zero. if it's been opened or allowed to warm up at some point. as a raccoon-type eater, i would chew it suspiciously while glancing around in a state of vigilance and await the consequences near a place i felt comfortable having sudden diarrhea.

salt i an interesting food component. it's the only rock we eat, and we need some to survive. it doesn't show up in plants, but we can find it in the earth (and other animals). and it stops bacteria from doing its thing in high enough quantities. it makes everything taste more. and too much jacks up our circulatory system.

there's a kind of occasionally foodie douche book about salt that is otherwise totally fascinating. Salt: A World History by Mark Kurlansky. full of weird little trivia about how critical salt was to human culture since the earliest days of even pre-history. how tons of names of peoples and places are exonyms for "salt" given by peoples who traded for it and are no longer extant to people who controlled access. not to mention its relevance as a critical resource to the age of conquest and exploration, the salt packed barrels of "food" (the descriptions sound terrible - apocalypse food) that could allow crews to survive as they sailed great ocean expanses where nothing edible could be found and anything not packed in salt would be rotten. there's a lot of covergent stuff around condiment flavors that come and go and come back again over time, appearing and reappearing in different cultures.

Salt is common, easy to obtain and inexpensive. It is the stuff of kitchens and cooking. Yet trade routes were established, alliances built and empires secured – all for something that filled the oceans, bubbled up from springs, formed crusts in lake beds, and thickly veined a large part of the Earth’s rock fairly close to the surface. From pre-history until just a century ago – when the mysteries of salt were revealed by modern chemistry and geology – no one knew that salt was virtually everywhere. Accordingly, it was one of the most sought-after commodities in human history.
