A new study suggests that using copper utensils while cooking prevents the cross contamination of food items with E.coli bacteria.

Lead researcher Bill Keevil said that while the study has not specifically looked at O104, copper’s effectiveness against all of the new strains of the bacteria were studied. “A study looking at copper's efficacy against new strains of E. coli has just been completed. Although it did not specifically look at O104, all the strains investigated have died rapidly on copper”, he said.
