Must be Considered :
Onions are a huge magnet for bacteria, especially raw onions. You should never keep a portion of sliced red onion. It is not safe even if you put it in your refrigerator. Onions are contaminated enough just by cut and left open for a little while, so that it can harm you (need to be more vigilant and more of the onion that you put in hot dogs) If you take the rest of the onion and cook it, you'll probably be fine , but if you cut the remaining onion and put on a sandwich or hot dog, then you're asking for trouble. Both onion and potato in a wet potato salad, will attract and grow bacteria even faster than commercial mayonnaise will begin to deteriorate.
Please remember, it is dangerous to slice the onion and tried to use it to cook the next day, red onion into very toxic even for one night and created a toxic bacteria that can cause bad stomach infection due to excess secretion of bile and even food poisoning.
