  • Duration: 04:52
  • An investigation into the best way to wash hands to reduce the risk of food poisoning. Hands washed thoroughly with soap have a significantly reduced number of bacteria. Every year up to four and a half million people in the UK suffer with food poisoning caused by unseen microbes. The number of microbes can be reduced by washing hands but is this enough in the food industry? Does it matter how you wash your hands? These questions are explored through some fair tests. At the start of the test the bacteria or microbes are invisible. Twentyfour hours later it is possible to see the bacteria on the incubated test plates. The testing proves there is a significant difference between the number of bacteria carried on quickly washed hands and the number carried on thoroughly washed hands.
