If you are worried, I think you can buy patuerized eggs now. I'm not quite sure what the process is, but they are much safer. I think it is only one in 20,000 eggs that may have trace samonella in it (sp?). Athletes guzzle down raw eggs all the time, so I'm not sure if there is a great risk. We used to eat raw batter all the time when we were kids. I'm betting that one lick of batter isn't going to hurt a kid with a good immune system, but I'm really not sure. There is probably a greater risk of getting sick from undercooked chicken or samonella from other sources, especially at restaurants from cross contamination. If the batter is fresh and the eggs were refigerated there is less risk, if you let the batter sit around and warm up, the bacteria will grow and multiply, that is how people get sick from salads, etc.

One of several types of bacteria which can cause food poisoning (salmonellosis) if ingested in large numbers. It is found in the intestinal tract of animals, birds, insects, reptiles, seafood, and people. The bacteria can easily be passed from the intestinal tract to the hands and onto food.
Although the inside of the egg was once considered almost sterile, Salmonella enteritidis (Se) has been found recently inside a small number of eggs (much less than 1%). If an egg does contain Se, the numbers in a freshly laid egg probably will be small and, if the eggs are properly refrigerated, will not multiply enough to cause illness in a healthy person.
The majority of salmonellosis outbreaks have been attributed to foods other than eggs—chicken, beef, and fish—to human carriers, and through them, utensils and other foods during preparation. Of the outbreaks involving eggs, almost all have occurred in the foodservice sector and have been the result of inadequate refrigeration and insufficient cooking.
Se will not grow at temperatures below 40ºF. and is killed at 160ºF., known as the danger zone, are ideal for rapid growth.
Illness from Se can be avoided through adequate refrigeration, proper cooking and sanitary kitchen and food handling procedures
