In today's germic and phobic world, many people probably do not want to hear the amount of bacteria in their food. But too bad, these researchers say! They studied how many saliva bacteria are transferred to the cake when someone blows birthday candles. And they found that yes, "blowing the candles on the surface of glaze caused 1400% more bacteria compared to the non-blown glaze". But hey, nothing says "Happy Birthday" like bacteria covered with frosting ... mmm!
Bacterial transfer associated with candles to blow on a birthday cake
"This study examined the potential spread of bacteria when blowing candles on a birthday cake. Preliminary Nutrient Blowing tests indicate that bioaerosols in human breath expelled from the mouth can be a source of bacteria transferred into To test the transfer of aerosol to the cake, the icing was evenly distributed over the foil, then birthday candles were placed through the sheet in a Styrofoam ™ base. Consumed the pizza, the test subjects were invited to extinguish the candles by blowing in. The icing samples were recovered sterile and then were surface-clad, to determine the level of bacterial contamination.The candles on the surface of glaze Resulted in a 1400% increase in bacteria compared to unbuffered glaze. E oral bacteria to glaze by blowing out birthday candles, transferring bacteria and other microorganisms from the airways of a person blowing candles to food consumed by others is likely.
