Left-over Onions.... dangerous

I must say I am the biggest culprit when it comes to storing left over onions. There are times when I can't get any Bombay/Indian onions from the local hyper market. So, I would buy the red onions from Australia. Oh, these are huge compared to the Indian ones. See the picture here. That is one! For one sandwich, there will definitely be left over. What I normally do is, keep the balance in an air tight container. Isn't this something we do almost all the time to the left over onion? Oh NO! You shouldn't do that. Just read on to find out more.
Following text was sent to me.
I have used an onion which has been left in the fridge, and sometimes I don't use a whole one at one time, so save the other half for later. Now with this info, I have changed my mind....will buy smaller onions in the future. I had the wonderful privilege of touring Mullins Food Products, Makers of mayonnaise. Mullins is huge, and is owned by 11 brothers and sisters in the Mullins family. My friend, Jeanne, is the CEO. Questions about food poisoning came up, and I wanted to share what I learned from a chemist. The guy who gave us our tour is named Ed. He's one of the brothers Ed is a chemistry expert and is involved in developing most of the sauce formula. He's even developed sauce formula for McDonald's. Keep in mind that Ed is a food chemistry whiz. During the tour, someone asked if we really needed to worry about mayonnaise. People are always worried that mayonnaise will spoil. Ed's answer will surprise you. Ed said that all commercially- made Mayo is completely safe. "It doesn't even have to be refrigerated. No harm in refrigerating it, but it's not really necessary.." He explained that the pH in mayonnaise is set at a point that bacteria could not survive in that environment. He then talked about the quaint essential picnic, with the bowl of potato salad sitting on the table and how everyone blames the mayonnaise when someone gets sick. Ed says that when food poisoning is reported, the first thing the officials look for is when the 'victim' last ate ONIONS and where those onions came from (in the potato salad?). Ed says it's not the mayonnaise (as long as it's not homemade Mayo) that spoils in the outdoors. It's probably the onions, and if not the onions, it's the POTATOES. He explained, onions are a huge magnet for bacteria, especially uncooked onions. You should never plan to keep a portion of a sliced onion.. He says it's not even safe if you put it in a zip-lock bag and put it in your refrigerator. It's already contaminated enough just by being cut open and out for a bit, that it can be a danger to you (and doubly watch out for those onions you put in your hotdogs at the baseball park!) Ed says if you take the leftover onion and cook it like crazy you'll probably be okay, but if you slice that leftover onion and put on your sandwich, you're asking for trouble. Both the onions and the moist potato in a potato salad, will attract and grow bacteria faster than any commercial mayonnaise will even begin to break down. So, how's that for news? Take it for what you will. I (the author) am going to be very careful about my onions from now on. For some reason, I see a lot of credibility coming from a chemist and a company that produces millions of pounds of mayonnaise every year.' Also, dogs should never eat onions. Their stomachs cannot metabolize onions .Please remember it is dangerous to cut onions and try to use it to cook the next day ,it becomes highly poisonous for even a single night and creates Toxic bacteria which may cause Adverse Stomach infections because of excess Bile secretions and even Food poisoning. :o)

The reason that you may not have heard this about onions before is because it is simply not true. This is just a hoax email that's being doing the rounds for ages.

This is ridiculous. Onions and garlic are very healthy and I always have peeled onions with out the bottom cut off so they don't weep in my fridge ready for use and I add onions raw and cooked to every food.It is wonderful for people with cholesterol or vascular issues that run in my husbands family and the peeled onions have helped to make him healthier.I have done this for about 50 plus years no one has been sick or died yet.Look at the mayo bottle see all those additives thats why it is not going too spoil ,not because it is natural or extremely healthy. I will continue to buy onions by the 10 pound bag and peel 5-6 at a time and store them in a plastic bag in the fridge,and should I make someone sick or die I will let everyone know.!!!
