LEFT OVER ONIONS ARE POISONOUS

chadqa's picture

Share ko lang ang info na ito sa mga Qler's ko.
may nag forward lang po sakin sa email.

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 infectionsbecause of excess Bile secretions and even Food poisoning.

i'd look up this info a bit more, madalas ko kasing gawain yung gumagamit ng tirang sibuyas (madalas may matira dahil nagiisa lang naman ako sa lutuan). so far wala pa naman nangyayari sa akin (knock on wood). anyway, mabuti na din yung sigurado, thanks for the info.

You decide. Read this => Cut onions toxic?

Personally, the way the email is written, it looks like a hoax to me. Well, some says that all vegetables and fruits that touched the ground can grow bacteria after cutting, like water melon.

kaya nga nagkaroon ng sizes varieties ang mga sibuyas:

pag pangmalakihang handaan...
yung super extra large ang bibilhing sibuyas para less labor sa pagbabalat at mas mabilis maghiwa ng maramihan.

pag pangrestoran...
ganun din... yung super extra large ang bibilhing sibuyas para less labor sa pagbabalat at mas mabilis maghiwa ng maramihan.

pag panlutong bahay lang...
yung midgets ang kinakailangan bilhin... di sing-busisi magbalat pero wlang naaaksaya. kung malalaki ang ginagamit, mas malaki ang tsansa na hindi maubos lahat gamit at masisira lang.

Isang properties kasi ng sibuyas, nawawala ang aroma kapag ito ay nahiwa at nahayaang naka expose sa hangin, tendency, nawawala na rin ang kakayahang mag absorb ng amoy ng iba pang sangkap lutuin.

MAS FRESH ANG SANGKAP, MAS MASARAP ANG NILULUTO, MAS OKEY KUNG BAGONG HIWA.

smurfpet06 said Hello po, i agree with you Chadqa...you are absolutely right ...

never use left over veggies once it was cut.But it's not because of the mayonnaise,potatoes and onions only that causes food poisoning on that salad..As far as i know,any salad /cold food that is not kept in the right temperature will cause bacterial growth faster(it's called Temperature Danger Zone)Cross contamination also can cause bacterial growth from the utensils that has been used for cutting,chopping and serving.It all depends on how we handle our food.

To keep our food safe "keep hot food hot and cold food cold".

Nice one Chadqa very informative.Thanks.

Good thing I never eat uncooked onions and even hate slicing it.....made me cry for no reasons, and oh the smell of onions caused me headache.

I hate to point out the obvious, but wasn't Ed in the Mayonaise business. Very convenient to blame the onions and NOT the Mayo. I'm not saying wether his correct or not. To me it sounds like a used car dealer saying "This car is great and if anything goes wrong, it's probably the gas you use - not the car. Now, would I lie to you??" ;-)

But better safe than sorry, I guess...

If everything seems under control, you're just not going fast enough...

How about salads with chopped onion? Restaurants have salad bars that may stay for a few hours before consumption?

nicaq25 said sa ating mga pinoy ...

nakasanayan na nating magbudget kahit sa simpleng bagay gaya ng sibuyas. Pagmalaki ang size, hahatiin at itabe ang natira for the next use. Well, sa edad kong ito, the practice of the above had not yet taken its toll.
Nagtataka kasi ako, kasi yung mga namamatsoy sa mga tira-tira ng mga food chains dun sa atin ay bihira lang nga naimpatso eh. Why I'd be so scared of these left-over onions?
