Jillian,
Rice is one of the biggest causes of Food Poisoning etc, but if you haven't been ill, I cxannot imagine you have anything to worry about, as long as it is freshly coked &/or piping hot...

We also consumed kilos of rice, but DH cooks it at home & we add meat & veggies to it, so it is not likely to cause anything!

Relax, you'll be fine!
