Remove the shrimp from the refrigerator and discard it immediately.
Remove everything else from the refrigerator and inspect it for the offending smell. If juices from improperly packaged shrimp have leaked onto other foods, they will need to be discarded if not properly packaged.
Set foods that are safe to go back into the refrigerator into an ice chest during the cleaning process to keep them cool.
Remove the shelves and trays and wash them with warm soapy water.
Wipe down the inside of the refrigerator with a solution of 2 cups hot water and two tablespoons baking soda using a sponge or cloth.
Leave the door to the refrigerator open for at least 15 minutes to allow it to air dry.
Place the food back into the refrigerator once the odor is gone.
