Good suggestions, all. Thanks. I keep my grains in sealed jars because my mom had a bug infestation of the kind that Manduck mentioned. I don’t fault Whole Foods for the bugs. I’ll still shop there, but not from the bulk bins.
I think I’ll be doing the freezer thing from now on.
I once had a bug infestation from some oranges from a neighbor. These flipping maggots were hanging from the ceiling. Spraying them with ammonia did wonders for that bloodthirsty streak.
I should mention that my infestation was not from bulk stuff. It was from a 20-pound pre-packaged sack of rice. I thought it would be smart to buy in quantity since rice keeps so well. The sack was in my cupboard for a few months before I had occasion to open it, so the infestation had really taken hold.
Anyway, I now just buy the little one and two pound bags, just like everybody else. And sometimes I buy a bit from the bulk bin
Seriously, I don’t think the bulk stuff is any more likely to have bugs in it than the packaged stuff.
That silverfish story gave me the creeps. I hate silverfish. Hate them. I picked up a towel in my bathroom the other day and a huge silverfish crawled out of it. I was so horrified I stood frozen before I could wad up some toilet paper and smush it.
I once found a roach larva in a bowl of rice. I found it just in time.
