Failure to Ensure Dietary Staff Competency in Dishwashing and Sanitizer Testing Procedures
Summary
The facility failed to ensure that kitchen staff were regularly trained and evaluated for competency in dishwashing procedures, as evidenced by staff being unable to correctly demonstrate and verbalize the process for checking quaternary ammonium compound (QUAT) sanitizer concentration and proper dishwashing techniques. During observation, a dietary aide washed a mixer in the three-compartment sink, followed the wash, rinse, and sanitize process, but then rinsed the mixer with water in the preparation sink, which is designated exclusively for food preparation. The dietary aide acknowledged this was a mistake, as the final step should have been air drying, not rinsing with water, to prevent chemical contamination. The dietary supervisor was unsure about the correct duration for dipping items in the sanitizer and incorrectly stated that spraying with water after sanitizing would be acceptable. Further observations revealed that both dietary aides and the dietary supervisor did not follow the manufacturer's guidelines for QUAT sanitizer concentration testing. Staff demonstrated incorrect procedures by dipping test strips for 15-20 seconds instead of the required 10 seconds and did not check the solution temperature as specified by the manufacturer. The dietary supervisor confirmed that these deviations could result in inaccurate readings and improper sanitization, potentially leading to cross-contamination. Review of facility policies, job descriptions, and competency checklists showed that while staff were deemed competent in some areas, there was no specific verification of competency for air-drying procedures or adherence to the correct sanitizer testing protocol. The report notes that these deficient practices had the potential to result in harmful bacterial growth and cross-contamination, which could lead to foodborne illness in 133 of 206 medically compromised residents who received food and ice from the kitchen. The findings were based on direct observation, staff interviews, and review of facility policies, job descriptions, and relevant food safety codes.
