A Clean SlatePreparing food on copper surfaces could prevent thousands of potentially fatal cases of poisoning each year. The stainless steel surfaces often used in the food industry are pitted with microscopic scratches which can harbour bacteria… Research… has shown that at 4 degrees C the common bacterium E. Coli 0157 can survive for 35 days on stainless steel, but lasts less than 14 hours on copper.
