Eating at a buffet, while very popular and allowing you to eat to the max, may also expose you to many disease causing agents! Touching the serving utensils is like shaking every person's hand in the establishment. Some of these people just coughed or sneezed into their hands, others just went to the bathroom and did not wash their hands. Buffet borne bacteria and viruses can make you sick.
PositiveTip: Use hand sanitizers to clean your hands before touching your food.
