NSF International Communications Manager Greta Houlahan comments on the recent Cryptosporidiosis incident in the Northampton and Rugby areas in the UK.

After reading the FoodBev article: '<1>', Houlahan wanted to introduce FoodBev readers to the NSF/ANSI Standard 53: Drinking Water Treatment Units - Health Effects.

The water treatment systems certified to NSF/ANSI Standard 53: Drinking Water Treatment Units - Health Effects can potentially help protect against a wide array of microbiological, chemical or particulates, including cysts. NSF International tests and certifies water treatment systems used to reduce contaminants, such as cysts, from drinking water. It is important to note that products certified under this Standard are not required to be effective against all contaminants for which testing is available. NSF Certification to NSF/ANSI Standard 53 includes ongoing monitoring to ensure products continue to perform as originally certified, that the information on the product label is accurate, and that the product does not introduce harmful levels of metals or other contaminants into drinking water.

To find water treatment systems that have been certified by NSF, visit[ http://www.nsf.org/Certified/DWTU/]<2>

To determine which products have met the cyst reduction requirement, check the 'Cyst Reduction' box under 'Reduction Claims for Drinking Water Treatment Units - Health Effects'.
