Laboratory performance evaluation of the U.S. Department of Agriculture (USDA) Food Safety Inspection Service (FSIS) Science chemistry sections is administered by the quality assurance coordinator, who operates interlaboratory check sample programs (known and blind), uses the accredited laboratory program and contract laboratory generated check samples as an outside data source, and conducts onsite laboratory audits. USDA-FSIS-Science laboratory chemistry sections have improved their ongoing analytical capability by the adoption of a formal Quality Control and Quality Assurance Program. Each chemistry section has appointed a Laboratory Quality Control Officer; keeps a Laboratory Standards Book, laboratory performance charts, analyst performance charts, and critical control points evaluation for each analytical procedure; maintains sample tracking control; and operates an intralaboratory check sample program with the associated feedback and corrective actions being taken and recorded.
