I don't know- I'm with the OP, I almost NEVER throw anything out,
it has to be unsafe- as in "when in doubt, throw it out"
but that's probably because I'm still feeding two teenage boys
in addition to the hubby and adult daughter-
the frig is almost always empty-
we go thru a staggering amount of food- so when something turns up in the back of the freezer-
it gets tossed into a soup or stew or jambalaya
and becomes part of something else and no one is the wiser.....
maybe your pork could be part of red beans and rice?
