Recently on a BBC board, a lot of discussion ensued about never eating leftover rice, even your own. Everyone was certain you would get food poisoning from it. I had never heard of this and did a little digging. I found some UK weblinks but none in the top of the search from the US, though I am sure they exist.
I do not doubt this bacteria causes the problem, I just never hear warnings about rice. Mayonnaise, meats, eggs, etc, but not rice.
Do you eat rice that is leftover?
