Apart from the idiotic headline (Can You Eat Cold Rice? Well, obviously yes. The real question s "is it harmful to do so?") the article is a mish-mash of yes and no. A first read suggested to me that no matter what you do the bacteria/spores combo will thwart your best efforts nit to die.
On the other hand my reasoning tells me that humans around the world must be eating cold rice (with whatever processing is performed) and not dying. So why all the fuss?
Given my age, I probably have a higher risk of food-poisoning than i did fifty years ago, and in the end one factor is bound to "do me in".
I have a jar of rice pudding that I made almost three years ago, and a jar of carrots preserved in Toronto four years ago.
I rather think that, in both cases, boiling the heck out of them (well, twenty minutes, say) will do in whatever "live" stuff is in there, and that immediate consumption will allow my gut bacteria to dis-assemble the spores into protein before they can do whatever it is they do.
That is, I still trust my gut bacteria to do their job.
