You will no longer want to blow birthday candles when you know the truth

Good thing, just by blowing birthday candles, it increases the amount of cake bacteria to 1,400%.

Burning candles and blowing candles is considered an integral part of any birthday party.

However, experts at Clemson University in South Carolina discovered the "terrible" truth. The habit of blowing birthday candles has increased the spread of bacteria by up to 1,400%.

To draw this conclusion, Dr. Paul Dawson and his colleagues at Clemson University conducted a study with a group of college students to help them have a better view of food safety.

Specifically, the team covered 1 layer of paper on the surface of the birthday cake. Before that, they had fun eating pizza together - to stimulate the salivary glands and felt like I was attending a real birthday party.

After that, they lit candles for birthday cakes and blew candles as usual.

The paper covered on the cake will be taken for testing. They are cut into small pieces, soaked in honey solution - the water is disinfected and placed on a microbial disc in the "characteristic agar medium" to see the speed of bacteria growth.

Dr. Dawson said that this is not the most accurate way to measure bacteria, but this is considered a classic classic method.

The team found that there are many bacteria, including strange bacteria that appear on agar plates. On average, blowing candles has caused the surface of the birthday cake and the neighborhood to grow up to 14 times.

In some cases, this number increased to 120 times. However, Dawson said, perhaps you should not ruin this habit during your birthday.

Doctor said: " In my opinion, you will still enjoy the birthday cake after the owner of the cake blows the candle. I don't think you will get sick because each person's mouth is full of bacteria, and almost all of them are not harmful " .

However, if you are sick or weak, you probably should not eat cakes and blow birthday candles because this can be harmful to others as well.
