When Stored in the Refrigerator – A cucumber, once picked, will keep for approximately one week when stored in the refrigerator. To determine whether or not a whole cucumber has gone bad, you can use any two of your five senses. If it has a mushy texture rather than a firm one, it is not good; however, if only one end is soft, you can chop off the soft part and eat the hard end.
Do not consume the skin if there are any signs of mold development on it. Mold may be removed from hard fruits and vegetables that have a low water content by cutting away an inch or more of the flesh along with the mold. However, this is not possible with fruits and vegetables that have a high water content since mold cannot be removed from these foods.
Mold has roots that are similar to threads, and its spores may readily move through or contaminate the flesh of an entire cucumber because of its high water content.
What do bad cucumbers look like?
How is it possible to tell whether a cucumber has gone bad? – Look. The skin of a cucumber should be firm and rather smooth. If you see that it has developed creases or dents, this is an indication that the cucumber is getting on in years and has most likely gone rotten.
Additionally, you could see a change in the hue of your skin. Mold is always an indication that a cucumber has gone bad. If a piece of a cucumber has mold on it, you should not try to chop it off and eat the remainder of the cucumber. You may not be aware of how deeply mold may penetrate foods, but it’s much deeper than you think.
Touch. If your cucumber feels slimy when you touch it, then you should not eat it. In addition, the flesh of a rotten cucumber will be mushy rather than solid. Don’t even entertain the thought of consuming any of the squishy ones. 
Can bitter cucumbers make you sick?
Why Is the Cucumber So Bitter? The fact that cucumbers are members of the cucurbitaceous family is one of the factors that contributes to the bitter flavor of cucumbers. These plants naturally contain compounds that are known as cucurbitacins. Cucurbitacins are the primary factor responsible for the bitter flavor of cucumbers.
A person’s susceptibility to illness can be increased if there is a significant quantity of cucurbitacins present. The second cause, which is not related to genetics, is the influence of the environment. If cucumber plants are given inconsistent watering schedules, allowed to become overheated, or are not fertilized adequately, they will almost certainly yield a vegetable that is bitter.
There is a possibility that one of the causes is the significant temperature swings that have been occurring recently.
How long can you keep cucumbers?
What is the shelf life of cucumbers? Cucumbers that have been cut won’t keep for more than a few days in the refrigerator, but whole cucumbers can stay fresh there for up to two weeks. If you keep whole cucumbers away from direct sunlight and store them at room temperature on the countertop, you may keep them for up to a week before they go bad.
