Effectiveness of sanitizing procedures was not observed
in all facilities. Sanitizer concentration usually was not
checked regularly by foodservice staff and almost never
recorded. Detergent was mixed with sanitizer in some
operations to “save steps” in the cleaning process, which
reduces sanitizer effectiveness. Nine facilities did not use
sanitizing buckets. Ware washing temperatures or sanitizing
concentrations were documented in 14 of 40 facilities.
In four facilities the temperature gauge indicated
correct rinse temperatures, but the temperature sensor
did not reach 160°F when the rinse water came in contact
with the surface to be sanitized. No sanitizing agent was
dispensed in a low-temperature dish machine in one facility.
