You know cooked potatoes are bad if they have a sour/foul smell, visible mold, a slimy or sticky texture, black spots, or if liquid separates (especially in mashed potatoes). These signs indicate bacterial growth, so discard them to prevent foodborne illness, as cooked potatoes only last 3-4 days in the fridge.
Comments Section
Cooked potatoes and other cooked vegetables can be safely kept in the refrigerator 3 to 4 days. The United States Food and Drug Administration (FDA) regulates fruits and vegetables, if more information is needed on produce, you can call the FDA toll-free at (888) 723-3366 or go to their website at FDA .
Green spots or patches: Green areas under the skin, or on the surface, can indicate the presence of solanine, a toxic compound, and should be avoided. Foul odor: A musty or rotten smell is a clear sign that the potato has spoiled. Mold or rot: Any visible mold or rotting on the potato means it's no longer good to eat.
Depending on how cold the fridge is you should be fine though 7 days is the far end of tolerance.
Freshly made mashed potatoes should have a smooth texture and an inviting off-white color. If they start to develop any discoloration—like gray or yellow patches—it might be time to reconsider that second helping. Similarly, if there are visible signs of mold (yes, even on mashed potatoes), toss them out immediately!
You can store peeled potatoes in water in the refrigerator for about 24 hours. Peeled potatoes left out by themselves at room temperature, on a refrigerator shelf or wrapped in foil or plastic wrap will still get dark overnight, so submerge them in a bowl of water, cover and refrigerate.
Solanine and chaconine can cause gastrointestinal symptoms such as vomiting, abdominal pain, and diarrhea. Some people might also experience headaches, flushing, confusion, and fever. There have been a few cases of death from eating toxic potatoes.
While a taste test is a braver way to tell, it's also a foolproof way! If they have a sour flavor or sour taste, throw them away. Discoloration. You know what color mashed potatoes should be (white and/or gold).
Store potatoes in a cool, dry, dark place. Peel the potatoes before cooking can reduce the amount of glycoalkaloids. Cut away any parts that show damage (cuts and bruises), rotting, green colouring and sprouting before cooking. In severe cases, discard the entire potato.
Usual guidelines for cooked leftovers is in the 3-4-5 day range. Some folks who are less risk averse will even push it to a week. 10 days is too long. If you eat it and don't get sick it's going to be your lucky day.
Can you reheat potatoes? 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.
If you grab your cooked potatoes and they smell sour or rotten, they are not good to eat anymore. Mold Visible mold definitely means your potatoes have gone bad. Look for brown, black, or green spots on the cooked potatoes to know they're past their prime.
Your potato is at a dangerous temperature when it is between 41–135 degrees Fahrenheit. Food experts call this range the temperature danger zone because within these temperatures, it is easiest for bacteria to multiply to unsafe levels on your food.
LPT: When potatoes are squishy, they haven't gone bad, they've just dried out. Potatoes are mostly water. They've only gone bad if: They are visibly molding/rotting. They have large roots growing from them.
Despite their nutritional value, potato tuber may harm human health by virtue of their toxic glycoalkaloids (solanine). Acute solanine poisoning can happen from ingesting green or sprouted potatoes. The toxicity of Gas in humans causes mainly gastrointestinal disturbances such as vomiting, diarrhea, and abdominal pain.
The best way to avoid solanine poisoning is to avoid eating green potatoes. It is not only important to keep potatoes out of the light for long term storage, but those stored under the counter, in a basement or root cellar that have started to grow eyes and become mushy and rotten can be dangerous also.
However, it is not worth the risk as it can cause diarrhoea, stomach cramps, fever, vomiting, nausea, and more. Potatoes that have turned green contain solanine. Solanine is a neurotoxin, and ingestion by humans can cause nausea, headaches and can lead to serious neurological problems and even death.
Unripe tomatoes and the green "eyes" of potatoes contain solanine that can cause moderate nausea, vomiting, headache and diarrhea. Eating large quantities can cause drowsiness, sweating, and changes in blood pressure and heart rate. Most effects are seen within 2 to 24 hours. Diarrhea may last for three to six days.
Symptoms range from mild yellow mottling on leaves to tuber necrosis (dying cells), which eventually kills the plant. Some plants don't show any symptoms, which makes it difficult for seed growers to remove diseased plants and leaves whole fields vulnerable to infection. PVY does not harm people or animals.
Answer. These should be fine for a few days, 3-4 max. The food safety issue with foil is that if the potatoes were taken from the oven, warm, and sealed up in foil, then left out at room temp for an extended period of time then you should not eat them.
The reasoning behind the old guidance lay around concerns over the possible formation of additional sugars when potatoes are kept in the fridge – sugars that can then convert into acrylamide when they're fried, roasted or baked.
Russet potatoes, like all other potatoes, are bad if they are soft, mushy, smell moldy, are shriveled/wrinkled, or have long sprouts.
