I have found them all over the place. You have to listen to the bird noises/clucking - and just follow. I found them in Broken Railroad and Mystery Lake.
Flour, in general, if kept dry lasts an extremely long time before going "bad". I loaded up a 155 day save on Interloper, and found a flour at 0%. I get Interloper is tougher and things decay faster - but flour shouldn't really decay/spoil like that.
Seems to be not a big deal - I can still use it in recipes at 0% (ruined). Just have to be careful to not store it or it will disappear like other items do at 0%.
