Disease prevention specialists warn against shaking hands as a form of greeting since this is a common way people spread disease. Eating at a buffet exposes people to the hands of everyone who came to the restaurant and touched the common serving utensils. It’s like shaking everyone’s hands in the restaurant. Diarrhea, anyone? Or perhaps the flu? Buffets are popular for being self-serve and all you can eat. You can even rummage through each serving platter to select your favorite parts. Unfortunately, the spoon or tong you are using to help yourself is the same spoon hundreds of other hungry people used to get their food. Some of these people just went to the bathroom in the restaurant and did not wash their hands. Others just coughed or sneezed into their hand or blew their noses because of a cold or flu. And few, if any, washed their hands before grabbing the same serving spoon you just grabbed. Then you use your hands to eat, introducing buffet-borne bacteria and viruses into your body. It’s enough to make you sick, and it often does. Food safety officials are concerned about contamination of the buffet food, which is why there is a sneeze guard covering the buffet items. Regulations require that utensils used in food preparation be changed every 4 hours. And if the serving utensils fall into the food, especially the handle, the entire platter of food must be discarded. But regulations do not address the serving spoons and tongs as vectors of disease from public handling. Of course, there are other things we all touch that can spread disease, such as door and faucet handles, especially in public bathrooms. But when you have these exposures in a place where you eat, there is an increased risk of disease transmission. What is the public to do? Here are some suggestions for making buffets less biohazardous: 1. The safest option is for the restaurant to have a server dishing out the food so only that server touches the serving utensils. The problem is this would be like a school cafeteria and turn people off, especially those who want unrestricted self-service. 2. The restaurant can offer disposable napkins at the buffet line for each customer to use to handle the serving utensils. The problem is the napkins can be accidentally dropped into the food, which would require the entire platter to be discarded. And there is the added waste of used napkins. 3. There could be a hand sanitizer available for use at the buffer line. But not everyone would use the sanitizer, so the utensils would still be a source of contamination. 4. Patrons can use their own hand sanitizers before eating. This is a good idea no matter what. Of course, you could also choose to avoid buffets. But for those who enjoy the smorgasbord experience, a little common sense and hand hygiene can help you avoid communicable diseases.
