God, terrifying!! I'm a chef with my own place, and we have a friend who's an EHO, whenever we have him round for Dinner (at home) I'm terrified!!
For rice, by far the easiest, safest way to cook and hot hold rice is with a rice cooker with a keep warm function. It flicks to keep warm as soon as it's cooked so isn't overdone, and will safely keep your rice hot for you. Apart from that, follow pp's advice and you'll be fine.
If you have a digital probe/ thermapen/ food thermometer you can check the temp if the rice, it needs to stay above 63C - this is the legal safe limit.
