Study suggests blowing out birthday cake candles could be health risk

The next time you blow out the candles on a birthday cake, you may want to wish for a strong immune system.

A study published in the Journal of Food Research found that blowing out birthday cake candles left behind 1400 percent more bacteria on the cake's frosting than if candles were not blown out on the cake.

The study suggests that those with health concerns may want to take safety measures when engaging in the birthday cake tradition.
