Apples
As apples have a tendency to produce ethylene, it is unsafe to put them in the fridge. Apples will ripen more quickly if we put them with other fruits and vegetables and there are chances that you will end up with spoiled fruits and vegetables

Apple could remain healthy for one or two weeks on the counter and they can be nice and decorative with their delightful colour. So for keeping them good for a long period if you put them in the fridge just make sure they are separated from others and keep in mind that one bad apple can ruin the whole bunch.
