From an E-mail I got tonight:
...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. Ed says it's not the mayonnaise (as long as it's not homemade Mayo)

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...
