Inspector's notes
At the three compartment sink, observed a worker washing and rinsing , but not sanitizing, wares including plastic containers, a metal grill press, and metal food pan. Food-contact surfaces must be properly sanitized after washing and rinsing. After advising PIC, the sink was filled with about an inch of sanitizer solution, which was not enough to submerge the wares in. She indicated that the unit did not have enough water. PIC will correctly complete the three step process of warewashing at the commissary after the event. Corrective Action: Corrected at time of inspection.
