Does mayonnaise need to be refrigerated?
Simply answer: Yes and No
- Home made: Yes
- Commercial made mayonnaise: No [Always,
follow the instruction on the label]
The FDA: Other foods containing raw eggs, such
as homemade ice cream, cake batter,
mayonnaise, and eggnog, carry a Salmonella risk too. Their commercial
counterparts are usually made with pasteurized eggs; that is, eggs that have
been heated sufficiently to kill bacteria, and also may contain an acidifying
agent that kills the bacteria. But the best practice, even when using products
containing pasteurized eggs, is to eat the foods only as they are intended to be
eaten, so answer C, sampling the unbaked store-bought cookie dough, will not
earn you any points.
US Food and Drug Administration: Check storage
directions on labels. Many items other than meats, vegetables, and dairy
products need to be kept cold. For instance,
mayonnaise and ketchup should go in the refrigerator after opening. If
you've neglected to properly refrigerate something, it's usually best to throw
1: Follow the instruction on the label.
It doesn't matter what your friends tell you and what you did growing up when it
comes to your safety and the safety of your family -- who has seen a commercial
made mayonnaise not recommend that their product not be refrigerated?
NO one wants to waste food -- when in doubt
toss food you are unsure of -- then consult your doctor or the FDA and FSIS.
2: For quality refrigerate mayonnaise.
The product will last longer and taste better.
