While you are probably familiar with certifications related to energy and water efficiency, you may not know dishwashers can also be certified to sanitize glassware, dishes and cookware.
Next to handwashing, proper cleaning and sanitizing of kitchen work surfaces used for handling and preparing food are probably the most important ways to protect against foodborne illness at home. In fact, a 2011 germ study conducted by NSF found that the germiest place in most homes wasnít the bathroom, but the kitchen.
While itís important to regularly clean and sanitize kitchen countertops and sinks, the dishes and cookware used to prepare and serve food also need to be properly cleaned and sanitized between each use.
One of the ways to effectively clean and sanitize dishes is to use a dishwasher certified to NSF/ANSI 184: Residential Dishwashers. This standard helps confirm that a residential dishwasher can achieve a minimum 99.999 percent or 5-log reduction of bacteria when operated on the sanitizing cycle.
In addition to confirming the unitís ability to sanitize dishes and cookware, NSF/ANSI 184 also establishes minimum design and performance requirements related to cleaning effectiveness. NSF uses over 100 pounds. of cherry pie filling to test the cleaning effectiveness of residential dishwashers each year.
NSF/ANSI 3 establishes design, construction, material and performance requirements for commercial dishwashers used in restaurants and other facilities subject to public health inspections, while NSF/ANSI 184 sets requirements for residential dishwashers:
If you are in the market for a new home dishwasher and sanitization performance is important to you, give yourself peace of mind and look for a dishwasher that is NSF certified to NSF/ANSI 184.
