Here’s how much bacteria you spew on the cake while blowing out birthday candles.

In today’s germ-phobic world, many people probably don’t want to hear about how much bacteria is in and on their food. But too bad, say these researchers! They did a study of how much salivary bacteria is transferred to the cake when someone blows out birthday candles. And they found that yes, “blowing out the candles over the icing surface resulted in 1400% more bacteria compared to icing not blown on.” But hey, nothing says “Happy Birthday” like frosting-covered bacteria… mmm!
