How can you get the rotten smell of shrimp out of your refrigerator

nothing you can do.. had the same issue with fish juice from a previously frozen fish.. everything in the refrig started tasting like fish.. including eggs, milk, butter. yuck.

So sorry, it may be in the insulation. Baking soda isn't going to do it. Call the manufacturer and see what they recommend. You don't want to do further damage.

Get a charcoal filter they use in fish aquariums and put it in the refrigerator. It will eliminate the odor quickly with no mess or chemical smell s

Baking soda. Put boxes inside and sprinkle it on the shelves. It's the only thing I have ever heard about to get the smell out. It'll have to sit inside for several days. Oh, I think you will have to empty the fridge too.

when my freezer accidently got unplugged for a couple weeks, I washed it out as best I could, filled it with crunched up newspaper and used coffee grounds. I changed it out every couple days and by the end of the week it was a fresh as new. (I contacted a couple cafes and asked for their used coffee grounds. they happy to donate)

Wipe all the surfaces down with a bleach solution to kill any remaining bacteria-caused odors. Then, use the newspaper/used coffee ground recommendation from Bobbie in Bismarck.

Don't forget that most frost free refrigerators have a tray underneath where the condensation accumulates for evaporation... that may be contributing to the smell...
