Counter cleanliness in the US - beware the numbers of poor science

A recent article in Today's Homeowner Magazine entitled "For counter cleanliness - granite is the way to go" highlights some of the ignorance associated this subject. The article was based on a study undertaken by Dr Snyder at the Hospitality Institute of Technology and Management at St Pauls in Minnesota, USA, in which he conducted tests to measure the bacteria resistance capacity of six countertop materials such as stainless steel, granite, plastic laminate, tile, concrete, and wood. The test involved the contamination of each top with 2 billion Escherichia coli bacteria. The cleaning procedure which followed involved washing and rinsing each surface with soap and water followed by sanitizing with a vinegar-water solution.
