[1]Oops! In your rush to get to school, you drop a piece of toast on the floor. Do you throw it away or decide it’s still OK to eat? If you’re like most people, you eat it. Maybe you follow the “5-second rule”, which claims foods are safe to eat, if you pick them up within 5 seconds of dropping them. But you might want to think again. Scientists now say that 5 seconds are all it takes for foods to become contaminated with enough bacteria to make you sick.
[2]Bacteria can cause many kinds of illnesses. Some kinds of bacteria can grow on food. If we eat foods on which these bacteria are growing, we can become sick. One of these food-borne bacteria is Salmonella. It makes 1.4 million people sick every year. Earlier this year, 370 people became sick after eating peanut butter that had been contaminated with Salmonella at the manufacturing factory. Salmonella are often found in raw eggs and chicken. Cooking kills these bacteria, which is why it is so important to cook eggs, chicken, and other foods carefully.
[3]Being a good housekeeper is another good way to prevent infection. If household surfaces aren’t washed thoroughly, they can support Salmonella for weeks. A team of scientists at Clemson University in South Carolina have tested the 5-second rule, using sandwich ingredients. First, they placed a known amount of Salmonella cells on three surfaces: wood, tile, and carpet. They then placed a slice of bread and a slice of bologna(博洛尼亞大紅腸) on each surface for 5, 30, or 60 seconds. After just 5 seconds, both the bread and bologna picked up enough bacteria to make you sick.
[4]So forget the 5-second rule. If your toast lands on the floor, throw it away. Stick a fresh slice of bread in the toaster. And this time, be careful not to drop it!
