Can an unopened jar of pickles go bad? 

This brief article will address the query “Can an unopened jar of pickles go bad?” Also, we’ll discuss how unopened pickles can go bad, how to tell if they’ve gone bad, what pickles are and how they’re made, as well as if they’re healthy to eat. 

Can an unopened jar of pickles go bad? 

Yes, an unopened jar of pickles can go bad, however, given the nature of pickles being preserved in vinegar or brine, this may not occur for a relatively long amount of time. 

Pickling is carried out to make fresh produce less perishable. When submerged in brine or vinegar, the fluid limits the growth of bacteria and fungi, making food have a much longer shelf life in storage. 

However, the effects of pickling are not infinite, and on average, about 2 years after being opened and stored in refrigeration, they may start to go bad. Also, unopened pickles may last for up to 2 years after the expiration date printed on the packaging has transpired. 

How can unopened pickles go bad? 

Unopened pickles can go bad, on account of being poorly stored, or being part of a poorly handled stockpile. For example, pickles that are misplaced in storage space and left in a nook where they are easily overlooked may inadvertently lead to them reaching their expiration date.

This may happen in convenience store warehouses, or even in a person’s pantry. 

Also, unopened pickles can go bad prematurely if they were poorly packaged to begin with, for example, if the jars were not sealed properly or they weren’t stored adequately, and left in sunlight and high temperatures. 

Overall, it’s very difficult to encounter spoiled unopened pickles, but if it’s been less than or a little more than two years, they are still considered innocuous. 

How can I tell if unopened pickles have gone bad? 

The first way to tell if unopened pickles have been spoiled is to check the lid on the jar. If the “button” on the lid is pushed out, it means the pickles were not adequately sealed, and air leached into it, along with other things such as dust, and possibly bacteria and mold. Shoppers should reject any jarred food product with signs of a tampered or otherwise improper seal. 

Next, shoppers/consumers should check the integrity and visual quality of the pickles in the unopened jar. If there are any signs of microbes present such as bacterial colonies of molds growing on the pickles, it should be rejected and discarded, as it’s not safe to consume. Discoloring in general is a bad sign and means that the jar should be thrown away. 

Also, the formation of bubbles in a sealed, unperturbed jar is a sign of concern, as it will indicate that some chemical processes (commonly attributed to microorganisms that spoil food)  are going on, and likely consuming the pickles as a substrate. Signs of bubbling also merit disposal. 

Opening a sealed jar is also a way to check for spoilage. Pickles should only smell of vinegar or brine liquid, and any differing smells may be a sign of fermentation. Fermented pickles are noxious and should also be discarded if discovered. 

Checking the solution that the pickles are submerged in can also indicate whether or not something is off. For example, brine and vinegar should have a certain thickness that is visibly different from that of water (color aside). 

If the solution is suddenly thin and lacks body, it may be a sign that it underwent an aging process and separated into different components, at which point it will not be innocuous and should be thrown out, pickles and all. 

Lastly, the taste of the pickles is also indicative of their current state. If they taste slightly fermented or different from how pickles usually would, they may indeed have gone bad. 

Spoiled pickles should not be consumed under any circumstances, as their composition will have changed and made them noxious. 

What are pickles

Pickles are a processed food product, made from cucumbers that have been preserved in brine, vinegar, or another solution to extend their shelf life. The principle behind it is to age them in a solution with a low (acid) pH, that discourages the growth of the most common bacteria and fungi that cause food decay. 

While they do have a much longer than average shelf life, they will at one point spoil and no longer be fit for consumption, usually, two years after the expiration date marked on their labeling. 

Are pickles healthy to eat? 

Pickles can be considered a part of a healthy diet when consumed in moderation.

Their fermented nature makes them a source of probiotics (which are important for digestive health), and they are a source of beta carotene antioxidants, which reduce the risk of heart disease, some types of cancer, and other diseases. 

However, they also have a notoriously high salt content, and shouldn’t be consumed regularly, as a high salt intake puts one at risk of high blood pressure, or even increase the risk of stomach cancer. 

Pickles should be eaten in moderation and combined with exercise and a diet rich in fresh fruits and vegetables.
