Cooked potatoes and other cooked vegetables can be safely kept in the refrigerator 3 to 4 days.
Storing cooked potatoes
Store in an airtight container in the fridge for 2 days and in the freezer for up to 3 months.
To maximize the shelf life of cooked potatoes for safety and quality, refrigerate the potatoes in shallow airtight containers or resealable plastic bags. Properly stored, cooked potatoes will last for 3 to 5 days in the refrigerator.
Potatoes can last between 2-3 months after their best-before date, if they have been stored in a cold, dry, dark place. Potatoes stored at room temperate can last just 2 – 3 weeks.
Cooked mashed potatoes are a risky food for bacteria that can cause food poisoning because they contain moisture and contain some protein. So if mashed potatoes are cooked it is best to eat them within 3-4 days of cooking and reheated them to 165°F, this will kill any bacteria that may have formed.
Extra mashed potatoes? Lucky you. Cold leftover mashed potatoes can be reheated right back to their former hot, creamy, and smooth state.
Refrigerated, leftover potatoes are best reheated and served within two days of original preparation. Remember, when it comes to food safety it's always best to err on the side of caution.
Cooked potatoes and other cooked vegetables can be safely kept in the refrigerator 3 to 4 days.
The general rule for knowing if uncooked potatoes have spoiled include a soft/mushy texture, the potato has a bad smell, or there are dark spots on the skin.
Is it safe to eat a food after its use-by date? Probably, as long as it's been stored and handled properly and there are no signs of spoilage. But it may not taste as good. Any date stamped on the product refers to the food's quality — not its safety; it's a recommendation from the manufacturer.
Yes, it is safe to reheat potatoes. However, they must be stored properly after initial cooking. If they are not, it can result in the growth of a bacterium known as Clostridium botulinum, which can cause a fatal disease, botulism.
Never store potatoes in the refrigerator.
Not only does it not prolong shelf life even further, but the extra-cool temperature can potentially prove harmful by turning the vegetable's starch into sugar.
How long can mashed potatoes be safely refrigerated? A: You can typically mash the potatoes and keep them refrigerated for about two to three days. Be sure to keep them in an airtight container because if you don't, the pulp will oxidize and turn gray.
“When these are stored in the fridge, the starch in the potato is converted to sugar. When baked or fried, these sugars combine with the amino acid asparagine and produce the chemical acrylamide, which is thought to be harmful.”
The short answer is yes. Potatoes that have sprouted are still OK to eat, but only once you've removed the sprouts.
Even the familiar potato can be a cause of food poisoning. Recently, there have been many cases of food poisoning caused by potatoes grown by school children as a part of their classes.
Rotting potatoes give off a noxious solanine gas that can make a person unconscious if they've inhaled enough. There have even been cases of people dying in their root cellars due to unbeknownst rotting potatoes.
A: Once cooked (whole or cut) potatoes can be stored in water (with or without vinegar) without becoming discolored or mushy. But, water storage isn't necessary. Refrigerate the boiled potatoes in a sealed container and use within a couple of days.
Cooked starch foods like potatoes can grow germs if not kept either refrigerated and cold or hot over 140º F. Bake or boil the potatoes for potato salad, then cool. Refrigerate.

In terms of food safety, however, so long as you reheat the food at the correct temperature and for the correct duration of time, it can in fact be safely reheated multiple times. However, the Food Standards Agency (FSA) recommends that food is only reheated once, so follow this guidance wherever possible.
Eating carbs that have been cooked, cooled, and then reheated could help people lose weight. Reheated potatoes, rice, and pasta have more resistant starch, registered nutritionist Rhiannon Lambert explained. Resistant starch helps prevent blood sugar spikes and is more satiating, research suggests.
