Eliminating the spread of bacteria on food preparation areas is vital in both domestic and commercial kitchens. Fortunately, effective elimination of bacteria is a task which is made a great deal easier with the installation of quartz and granite worktops.
The presence of harmful bacteria on or near to areas where food is stored or prepared can have extremely serious consequences. Bacteria such as the virulent strain of E-Coli, for example, can, even in small amounts, lead to severe diarrhoea and, in some cases, kidney failure. The spread of such harmful bacteria on food preparation surfaces is impossible to detect by normal human senses alone; but can easily occur following contact by some raw meats or even certain raw vegetables.
The problem with some materials used for kitchen worktops is that they make the removal of bacteria extremely difficult to achieve.
Porous surfaces such as wood, for example, are strongly believed to allow bacteria to sink into and therefore infiltrate the surface, thus preventing elimination of the bacteria by surface wiping alone. Other materials used for kitchen worktops, particularly laminate coatings and aluminium, can scratch easily; such scratches, even tiny ones, having been shown to act as traps for bacteria.
Quartz stone worktops and treated kitchen granite worktops on the other hand are non-porous and extremely scratch-resistant. Tests have shown that a simple surface clean with soapy water, followed by a rinse, is far more effective at removing bacteria from granite and quartz surfaces than it is with wood, laminates, stainless steel, or even concrete.
