What do you do if you drop your sandwich on the floor? Pick it up within five seconds and just continue eating? […]

American researchers wanted to test  how long food has to be on the floor before it becomes contaminated. They dropped sausages and bread onto different surfaces, such as carpet, wood and tiles, and examined  the transfer of Salmonella bacteria.

They found that of all the bacteria that contaminated the food, 99 percent of them  had transferred already in the first five seconds. The time it took them was influenced by the kind of surface the bacteria were on, yet only a little. Bacteria on carpet took more time to get onto the sausages than those on wood or tile.
