Leftover Onions can be poisonous

I eat refrigerated left over onions all the time and never had a problem. I love onions, always have. Am i the exception? Billy in Florida

Hi, rosey19. This is the first time that I heard about this. When I slice up my onion, I will save the rest of another time. I do make sure that the onion is still fresh. I am unsure if having stomach problems have come from these onions. My stomach has been feeling funny lately. But, I can't tell where this is coming from. I hope it was the onions. It is like my stomach gets an stomach ache. Thanks for this information. I will need to be more cautious about this now.

Hello rosey and welcome to myLot. Onions are a very acidic vegetable and are very low in protein. Only foods high in proteins are at high risk for causing food poisoning. Cut onions do have a lot of moisture that can be a breeding ground for bacteria but because that moisture is acidic it drys too fast for bacteria to form. More than likely any food poisoning that is associated with the onions is because the person prepareing the food did not wash their hands or the prep area good. I have saved left over raw onions in my fridge for years and haven't had a problem. according to snope these ideas come from old wives tales. http://www.snopes.com/food/tainted/cutonions.asp http://chemistkitchen.blogspot.com/2009/04/onions-as-bacteria-magnets.html

Talking about this, I remembered an incident that happened to my second brother lately about one month ago. We ate some 'satay' which its condiments are the 'satay sauce' which makes from grounded groundnut paste, some slices of cucumber and onions. That late evening he experience diarrhoe and vomitting and admitted to the hospital. His stomach crammed and he felt weak for the nest few days. I just wonder whether it is the result of eating those sliced onions which could be exposed to some bacteria earlier on. There could be some 'truth' in those emails.

Thanks for sharing useful information.Personally i dont like to store already cu onion as it create very bad smell in the refrigerator and all the food items too starts getting stink.Anyway i will take care of it and provide this info to all who stores leftover onions.
