Most of us wash chicken before cooking thinking this is a good practice to avoid food contamination. Professor Jenifer Kwinlan of Drexel University says:
Salmonella and Campylobacter are bacteria which are the main causes of food contamination. When the chicken is washed in the kitchen sink, splashing bacteria are everywhere, even in you! Hot water alone can not kill the bacteria. People usually wash the chicken to clean up some dirt on it, clean if germs or just because it looks dirty to them. However, this is a wrong practice that only spreads the bacteria around, and there is no need to be exposed to this risk, as cooking the chicken will effectively kill off all bacteria inside.
There is no safe way to clean dirt – use a paper towel. Yes, you can use paper towels your kitchen to clean the chicken and clean up some of the bacteria on its surface.
Statistics show that 280,000 people in the UK are diagnosed with contamination of food a year, caused by washing the chicken and splashing around the bacteria mentioned above. Poultry farmers the incentives for pain if they manage to keep your bacteria-free chicken.
