Study: Blowing out Birthday candles increases bacteria on cake by 1400 percent
MICHIGAN — Close your eyes, blow out your candles and make a wish — what did you wish for? Was it a high amount of bacteria to settle atop the icing?
Bacteria are everywhere and usually already present on the cake, but by blowing out the candles a person is able to contaminate the baked treat with illnesses that are transferred pathogenically such as the cold or the flu.
During the study, a number of bacteria found on sample cake varied depending on the individual who blew out the candles and on average the number of bacteria increases by 15 times.
