Three Seconds Rule

Do you believe that food that falls before 3 seconds is still safe? 3 seconds of this phrase could be a tagline some time ago on a commercial floor cleaner.

In other countries such as the rule is commonly known as ‘three seconds rule‘. However, it still must continue to obtain more accurate data.

To prove it, Manchenster Metropolitan University (MMU) conducted tests on five types of foods such as bread with jam, pasta, ham, biscuits and dried fruit. All material is dropped on the floor for 3, 5, and 10 seconds.

This study uses three different types of time because each food has a different water content. This will be the key to how quickly the bacteria will grow on these foods.

When examined after the specified time, the result is food with a salt content and high sugar is still safe to eat.

Ham, one of salty foods and sweet bread with jam managed to escape in this selection. In contrast to the pasta with dried fruit.

When food is taken after 3 seconds it shows signs of Klebsiella which can be detrimental to health such as pneumonia, urinary tract infections, and septicemia.

“Ham is meat that has been preserved through salting process. Nitrates in it to prevent bacterial growth,” explained Kathy Less, technical officer MMU.

While the biscuits become most foods safe to eat despite having fallen for 3, 5, up to 10 seconds. This is due to biscuits contain relatively little water.
