22.214.171.124: Method for Washing Dishes by Hand
If the facility does not use a dishwasher, reusable food service equipment and eating utensils should be first scraped to remove any leftover food, washed thoroughly in hot water containing a detergent solution, rinsed, and then sanitized by one of the following methods:
- Immersion for at least two minutes in a lukewarm (not less than 75°F) chemical sanitizing solution. Bleach may be used as a sanitizing solution when diluted according to manufacturer's instructions. The sanitized items should be air-dried; or
- Immersed in an EPA-registered sanitizer following the manufacturer’s instructions for preparation and use; or
- Complete immersion in hot water and maintenance at a temperature of 170 °F for not less than thirty seconds. The items should be air-dried (1);
- Or, other methods if approved by the health department.
RATIONALEThese procedures provide for proper sanitizing and control of bacteria (2-4).
COMMENTSTo manually sanitize dishes and utensils in hot water at 170°F, a special hot water booster is usually required. To avoid burning the skin while immersing dishes and utensils in this hot water bath, special racks are required. Therefore, if dishes and utensils are being washed by hand, the chemical sanitizer method will be a safer choice.
Often, sponges are used in private homes when washing dishes. The structure of natural and artificial sponges provides an environment in which microorganisms thrive. This may contribute to the microbial load in the wash water. Nevertheless, the rinsing and sanitizing process should eliminate any pathogens contributed by a sponge. When possible, a cloth that can be laundered should be used instead of a sponge.
The concentration of bleach used for sanitizing dishes is much more diluted than the concentration recommended for disinfecting surfaces elsewhere in the facility. After washing and rinsing the dishes, the amount of infectious material on the dishes should be small enough so that the two minutes of immersion in the bleach solution (or treatment with an EPA-registered sanitizer) combined with air-drying will reduce the number of microorganisms to safe levels.
Air-drying of surfaces that have been sanitized using bleach leaves no residue, since chlorine evaporates when the solution dries. However, other sanitizers may need to be rinsed off to remove retained chemical from surfaces.
