Are sliced and stored onions bad for bacteria ?
Are cut onions bad
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.
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!)
SO ARE ONIONS REALLY BACTERIA ATRRACTERS
The notion that onions are a "bacteria magnet" may stem from an old wives' tale dating at least as far back as the 1500s, when it was believed that distributing raw onions around a residence guarded against the bubonic plague and other diseases by "absorbing the elements of infection." Believe it or not, though it has no scientific basis whatsoever, some people still believe this today.
