Swiss scientists analyzed cutting boards from hospital cafeterias and private home kitchens after they were used to cut poultry but before the boards were washed. They found that 6.5% of hospital cutting boards and 3.5% of household cutting boards were contaminated with drug-resistant E. coli bacteria. This could pose a major health risk if the cutting boards are reused before being properly disinfected or if any food exposed to the cutting boards is not cooked at high enough temperatures to kill any bacterial contamination.
