Cleaning is Part of the Operating Procedure

When purchasing equipment, look for models that have been tested and certified by recognized agencies that certify products and write standards for food, water, air, and consumer goods. Three prominent agencies are NSF International (formerly the National Sanitation Foundation), CSA International (formerly Canadian Standards Association), and Underwriters Laboratory. These three agencies are recognized internationally. Products meeting their testing requirements are labeled or marked accordingly (Figure 3.1). Criteria govern such factors as design and construction (for example, sealed joints and seams), materials used (for example, nontoxic materials, smooth and easily cleanable surfaces), and performance testing.
