This is the site that explains the do's and don'ts of storing pet food.

I buy 5 pound bags of food. I only have to feed one dog, so that bags lasts me 4-5 weeks. Therefore, I leave the kibble in the original bag and use a clip to close it.
I also keep mine in the original bag. I at one time used a plastic container but I read this site and just decided not to take the chance on something going wrong. Maybe in my old age I'm getting too cautious


I use the bin with wheels that is in the picture of that site. I have used it for years. I have always just poured the 40 pounds of food in it. I think I need to find a better storage bin
id have to wash and dry the bin every time they ran out of food due to the crumbs that inevitably fall to the bottom and look like a layer of dirt!
Sometimes we used to open the trucks to find cracked cases of Special Kitty with maggots in them.
