jaapfries Posted July 29, 2009 Share Posted July 29, 2009 Very Interesting...... Written by Zola Gorgon - author of several cookbooks.. Watch out for those spoiled onions... 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. NOW, I DID NOT KNOW THAT!!!! DID YOU??? Link to comment Share on other sites More sharing options...

Interesting, although this point would only make me more skeptical. I'd expect the CEO of a company to promote the product they're selling.

cathyy Posted July 29, 2009 Share Posted July 29, 2009 I have heard before that it's not the mayo. I heard it was more likely to be the eggs in the potato salad. Onions contain a natural antibacterial in their juice, just like garlic does. The issue with onions is salmonella or e.coli contamination of (usually imported) green onions, not sliced or diced red or yellow onions. You eat the outer layer of green onions, which is the most likely to be contaminated, and you don't with regular onions. Dude may know mayo, but he doesn't know onions.

Scott Posted July 29, 2009 Share Posted July 29, 2009 Well, it's always good to know, as your wretching your guts out that it wasn't the Mayo that made you sick, it was the onions...or was it the potatoes....or maybe the eggs? Link to comment Share on other sites More sharing options...

Yes, my japanese mayo in a plastic bottle carrying the baby pic is displayed on non-chilled shelves in the supermarkets. Onions? No leftover in mine...I love eating them raw and cooked.

Samuian Posted July 29, 2009 Share Posted July 29, 2009 - common sense - that's all... is needed! We had on several occasions the dreaded - but wonderful "Aioli" - homemade Mayonnaise - the horror of any "food-safety-agent" - in Tuscany/Italy at temperatures in the mid 30Celsius and higher... Never ever had a problem! But watermelon and ice cold beer or ice cream don't mix well... there are certain things, which just don't match!

Crossy Posted July 29, 2009 Share Posted July 29, 2009 Interesting thread but not directly Thailand related. I'll move it to Western Food (county Mayo is in Ireland isn't it ). Link to comment Share on other sites More sharing options...
lazygourmet Posted July 29, 2009 Share Posted July 29, 2009 Interesting thread but not directly Thailand related. I'll move it to Western Food (county Mayo is in Ireland isn't it ).sYes it is... But mayonnaise is originally coming from Mahon, which is the main town of Menorca, in the Balearic Islands. Link to comment Share on other sites More sharing options...
verydumbubba Posted July 29, 2009 Share Posted July 29, 2009 The part about onions is garbage. My dog & I have been eating Onions, Garlic, Leeks, etc for eons. He dont even have fleas. Mayo isnt food either - its 80% grease - nobody I know, even in Ireland - eats it. Bubba Link to comment Share on other sites More sharing options...
Crossy Posted July 29, 2009 Share Posted July 29, 2009 But mayonnaise is originally coming from Mahon, which is the main town of Menorca, in the Balearic Islands. At least that's one of the origin theories, others here http://en.wikipedia.org/wiki/Mayonnaise (which also supports the non-spoilage of mayo left un-refrigerated). My reference to Ireland was of course tongue in cheek just in case someone uses it as evidence of typical mod intelligence Link to comment Share on other sites More sharing options...

noahvail Posted July 29, 2009 Share Posted July 29, 2009 Just a quick comment: I use snopes.com to check on lots of these stories. They're great hoax-busters. They have this letter on file, and it appears that mayo is not what makes you sick. It also has a further explanation from the chemist at the factory. http://www.snopes.com/food/tainted/cutonions.asp The jury seems to be out about the onions, though...

Ulysses G. Posted July 29, 2009 Share Posted July 29, 2009 The eggs in commercial mayo are now pasturized or it would make you sick if not refrigerated. In the past, it did make people sick sometimes. I would be vey careful of home made mayo! Link to comment Share on other sites More sharing options...
AyG Posted July 30, 2009 Share Posted July 30, 2009 Sounds like one of those emails that goes around form time to time eg. plastic bottles cause cancer That's because it is! It's been circulating since March 2008 according to Snopes. And there's no evidence to support the theory that chopped onions are a major health hazard.

Beacher Posted July 30, 2009 Share Posted July 30, 2009 Wow, so store-bought mayonnaise isn't real food and onions can be dangerous. I guess I'll take them both off my shopping list. LOL Link to comment Share on other sites More sharing options...
sinewave Posted July 31, 2009 Share Posted July 31, 2009 i always keep half cut onions in my fridge uncovered then cut out the dried layered for use later, never had a problem. I think its more a combination of juices from the ingredients mixing together to form a toxin...when the breakdown temperature is reached. Link to comment Share on other sites More sharing options...
cathyy Posted August 1, 2009 Share Posted August 1, 2009 I think its more a combination of juices from the ingredients mixing together to form a toxin...when the breakdown temperature is reached. Tell me, do bacteria play any role in this disease theory of yours? Link to comment Share on other sites More sharing options...
