Processed luncheon meats and hotdogsDid you make sandwiches for the Little League team last week? It is time to throw out the unused meats if they have been in the fridge more than seven days. If the package is vacuum sealed and unopened the meats will stay good for two weeks.
MayonnaiseStore bought processed mayonnaise is made with pasteurized eggs and is good in the refrigerator for two months after opening. Homemade mayonnaise made with fresh eggs is only good for three days.
EggsFresh eggs are good for four to five weeks if they are stored on a shelf in the fridge. A handy way to check if an egg is fresh is to put it in a bowl of water. If it sits on the bottom horizontally, it is still good. As an egg ages, air infiltrates the shell and will cause the egg to become more buoyant.
Fish and shellfish
Fresh fish, shellfish, and shrimp will be safe for only two days in the refrigerator. Cooked fish and canned tuna will be good for four days if stored in an airtight container. Smoked fish can be safely eaten for up to two weeks in the fridge.
