Creme Brulee is a cooked custard, and as such is completely safe eaten warm, although if it gets too warm after cooking the custard can break making it unappetizing. By this I mean that if the custard is relatively fresh and is at room temperature it will not make you sick. (Assuming the eggs and cream are not spoiled and filled with toxins to begin with) It is possible for the custard to spoil after cooking, but that would take some time. It would tend to break and be a little unpleasantly runny well before it would be unhealthy.
It is made from egg yolks, cream, sugar and vanilla and is cooked in ramekins in a water bath at 300-350 degrees F for about 40 minutes. It is more than sufficiently pasteurized at that point. Traditionally, it is then chilled to set it. The last step is to caramelize a sugar on the surface. This can be brown sugar, white sugar, maple sugar or anything that can be caramelized and get crunchy. If the dessert is made in shallow ramekins, the custard will warm up during this step. No biggie.
