Is it necessary to refrigerate containers of bottled water after opening?
Bottled water under normal conditions should not require refrigeration after it has been opened. But there is the possibility of it becoming contaminated after opening and support growth of microorganisms, since there is nothing added to the water (like chlorine) to prevent such growth.

If you drink from the bottle, yes. our mouth has bacteria in in that can contaminate the bottle. If you pour it into another container, then no.
put it in the fridge it last up to 3 days Keep it in the freezer. Whenever you put soup away, boil it and put it in containers or jars. Refrigerate it while it's still hot. When you remove soup from a container, boil up the remainder. Store soup in small containers as opening them invites bacteria. Vegetable soups last longer than soups made with chicken or beef broth.
Commercially-prepared mayonnaise itself generally has a pH that would be considered shelf stable and would not support pathogen growth. Label state to "refrigerate after opening" to protect flavor, extend quality and slow rancidity. If you keep it out, the flavor will degrade, so get it into refrigeration as soon as possible. If you have containers of mayo at an event, you might want to provide an ice bucket to keep the mayo cold. At home…
I would suggest you refrigerate the opened container. If it was in the refrigerated section when you bought it, keep it refrigerated. If it was not in the refrigerated section, check the label for instructions like "refrigerate after opening". Absent those instructions, refrigeration would probably help protect flavor even if food safety might not be an issue.
You do not refrigerate Red Wines either before or after opening. White wines & Zinfandels, yes, but never Reds, whether Merlot or any other Red. Wine is 'alive' after a fashion, and when you open it the degeneration process begins. Refrigerating a red will only slow this process very slightly, will NOT stop it; further, the changes in temperature from the fridge to the room it's in will further degrade it. Reds are meant to…
MUSTARD: According to Frenche's website: "Dijon & Horseradish Mustard will lose heat and distinct flavor, so we encourage refrigeration for both. For all other mustards, refrigerating will help maintain its flavor; however, it is not necessary if you prefer your mustard to be room temperature. There are no ingredients in mustard that spoil. "Refrigerate After Opening" is not required for food safety. It is recommended to maintain optimal product flavor.
Yes. Opening the can negates the purpose of canning and exposes the pumpkin pulp to microbes which will grow and spoil the food. You should only open the can if you intend to immediately use the contents. If your recipe does not utilize the entire can, you can temporarily refrigerate the remainder or even possibly freeze it for somewhat longer storage.
From my experience I would say Yes. I've left a (Costco) apple pie (covered) on my counter. Within a few days mold grew on it. Costco apple pies are not factory made like boxed pies sold in the supermarket. Therefore they have a short shelf life. Boxed pies are sold non-refrigerated however, I still refrigerate them after opening.
no you don't have to refrigerate the jelly. Mostly the companies that make the jelly say that you have to refrigerate it because if someone were to get food sick from something (anything, not even the jelly) then its likely in this day-n-age of sueing that the jelly company will be sued because they didnt promote "good health" (much like mcdonalds having to put the caution warning that their hot coffee can burn because some…
