The article is a hoax but storing a cut onion in a fridge is still a no no as bacteria will grow fast on them.
It's also a myth that mayo won't spoil.

Hoax
Part 2
The message claims that left over, cut onions should not be used the next day, because they become highly poisonous because of bacteria growth, turn toxic and lead to adverse stomach infections. The message is not a fact, there is no scientific evidence to prove this claim.
Onions as such do not have any special property to magically attract bacteria from its surroundings. In fact, when onions are cut, they emits sulfenic acids which inhibit the growth of germs and thereby protect them from surrounding bacteria. This is because bacteria generally like moist and neutral environments, and they cannot stand acidic environments - that's why vinegar is used for preserving. Left over, cut onions are not poisonous, they are fine to use and can be stored in a refrigerator, in a sealed container at the proper temperature of 40°F or below for up to 4 days. You can also store them safely in zippered bags and use them within a day or two. But onions can lose their nutrient value when stored over a period of time.
However, it is also important to note that onions have to be handled in hygienic manner while cutting and re-using them, because they can be contaminated with certain bacteria when they come in contact with dirty hands or unhygienic cutting board, and consumption of such onions can indeed make a person sick. But again, this is possible with any other food item, not onions in particular.
Therefore, the message saying cut onions become toxic is a hoax, left over, cut onions are not poisonous, they are safe to use when stored in hygienic conditions. There have been many other versions of this story, claiming that leaving onions around a room will absorb the flu virus along with bacteria causing other illnesses and will prevent people from becoming sick. It is a fact that onions were used in folk medicine long before 1919, but it is just a false belief, there is no scientific evidence to prove it. Onions are not bacteria magnets, they are good to use, especially because they are high in vitamin C and are a good source of fiber and other important nutrients.

I love chilli with everything, chilli padi, sambal belachan, chilli paste, chilli flakes, chilli sauce, green chilli, red chilli, tobasco sauce, etc.
If ever there is a serious health problem from eating chillis...................
Once I saw a man eating a plate of hor fun in a Thai Express restaurant. He had with him a bag of onions and was eating them raw together with his hor fun.
I've never heard of onions being more bacteria prone. I've stored peeled onions in the fridge using only cling wrapper or storing them in tupper. Have always considered them as a vegetables/fruit.
