Can You Get Sick From Eating Old Onions?
It is extremely rare to get sick by eating an old onion. Onions rarely go bad, even if they are very old, and the chances of getting any illness from an old onion is equal to consuming any other fresh food. You can cut the spoiled part of an old onion and consume the rest safely.
If you do not experience bloating or cramping while eating onions, there is no reason to worry. Despite some myths, a bad onion is not more likely to lead to food poisoning than any other food.
The myth-busting website Snopes explained in 2009 that leaving sliced onions a few days does not allow onions to become contaminated, nor does it cause food poisoning, thus debunking the claim. It said leaving chopped onions overnight could turn them toxic, which could, in turn, lead to food poisoning.

Once chopped onions are stored overnight, they risk growing bacteria, and should be used only for cooked foods, not consumed raw in recipes like salads or sandwiches. Once you break off the onionas protective outer layers–aka, slice them–you should store them in a sealed container or sealed bag in the refrigerator, just like any other food items in your kitchen. Chopped onions will remain fresh in your refrigerator, when stored correctly in an airtight container, for up to 1 week or so. For chopped onions, be sure they are sealed in an airtight container or food-safe zipper bag before moving to your fridge or freezer.

Unless you cut the onions on a contaminated cutting board or handled them with soiled hands, you can safely place them in a plastic bag and store and they will not be subjected to any bacteria contamination. Now, if you cut your onions with a dirty knife, or on a dirty cutting board, then they can get exposed to bacteria, which could make you sick. The myth is that once you chop onions, they are breeding grounds for bacteria, to the point where leaving chopped onions in the refrigerator makes them toxic, even if only for one night. Yes, leaving onions exposed to light may be a breeding ground for food-borne bacteria, but not any more so than other perishable foods.
Old onions may grow mold, which spreads through the air,A but this is unlikely if theyave only been in the refrigerator for one day. If your chopped onions do come in contact with bacteria, it does not matter whether they were stored in the refrigerator overnight or used immediately. According to this e-mail, cut raw onions are a magnet for bacteria, and they should never be stored in the refrigerator, even for short periods. She warned that keeping chopped onions out of the refrigerator could destroy their freshness, and that eating them the following day is no good idea.

Chopped or chopped onions stored in a fridge last for up to one week, and they should be used for cooking only, and never eaten raw, after you have left your chopped or chopped onions overnight in the fridge. Preparated onions, stored appropriately in a zip-lock freezer bag and placed in a freezer, will last for up to 6 months. That is, if you do not have the space for a refrigerator, and keeping onions at room temperature is the only option, then raw, whole onions can last for two to four weeks at room temperature. Ideally, onions should be stored in a cool, dark area that is 45-55 degrees Fahrenheit. Whole, raw onions will last two to three months if stored cool, dry.
For instance, a chopped onion certainly goes bad in one or two days without refrigeration, but a whole onion is probably okay as long as it is not refrigerated, but kept somewhere dry. The best way to store onions, in order to prolong their shelf life, like fresh onions, is to keep them whole, skin-on, and store in a cool, dry place. In fact, you are better off not keeping your whole onions in your refrigerator, if you want to keep them long-lasting with good quality. You should not keep whole, unpeeled onions in the refrigerator because they will easily absorb moisture from the refrigerator, which may have an adverse effect on their texture.
Onions will also last for at least two or three months in the refrigerator — just keep in mind that their texture can become slightly soft in the refrigerator, since onions soak up moisture quite readily. Onions from Mexico last for up to three months in storage, which means that there could be a few left for your familys cooking and businesses. Any fresh, whole red can last up to three months in storage, the CDC notes, and could still be in homes and businesses. If you cannot identify where onions came from, toss them, do not buy or eat them, the CDC says.
There are several different ways onions can go bad, depending on if you are dealing with whole onions, sliced onions, or even chives or green onions. If you are eating large amounts of older onions with toxic bacteria on them, you could also end up with food poisoning, which is characterized by diarrhea, nausea, vomiting, and stomach pain. It is worth noting that if you just consumed a couple onion rings that are discolored or think that they are spoiled (after eating), in most scenarios, this would have no major impact, but if you consumed a large amount of onion (raw) with bacterial infections, it could lead to food poisoning in serious cases. On the other hand, it is possible that if you have left a peeled or chopped onion for a long enough period, then it would start growing bacteria, however, and this could lead to an illness if consumed.
An important thing to remember is to always store cut onions in a bag or an air-tight container, because the strongly-scented onions may induce their odor on to other foods that are in your refrigerator. If you have already cut or chopped onions, then you need to keep them in an air-tight bag or container in your fridge, or you can also keep them in your freezer for a good amount of time in plastic freezer bags or in an air-tight container. There is definitely no reason to be afraid of onions, just be sure you practice common food safety practices. One commonly-circulated claim holds that uncooked, unprocessed onions are toxic, as they are an enormous magnet for bacteria and therefore liable to spoil.
What happens if you eat an onion that’s gone bad?
Even if they are terrible, onions aren’t particularly or seriously hazardous. Contrary to the popular belief, rotten onions are not more likely than other foods to make you sick. You can safely consume the remaining onion after removing the damaged region if you discover that it has gone rotten.
How can you tell if an onion is bad?
Onions that have been spoiled may get dark stains, which will eventually start to sprout mould. Additionally, you should stay away from sprouting onions because this is a sign that they are starting to spoil. To determine how fresh your onions are, you can also feel them. Onions that have soft or mushy patches are beginning to spoil.
Are rotten onions OK to eat?
Mold on an onion’s outer surface is often in green or black color and can be in a powdery or sticky texture. Mold is more likely to appear as fine, white, threadlike spores on chopped onions. Moldy onions should always be thrown away because they are unsafe to eat even after cooking.
