Outline
Objective The application of quality control chart in the quantitative detection of Staphylococcus aureus in milk was discussed by collecting the routine detection process of Staphylococcus aureus in milk and testing the results of Staphylococcus aureus in quality control samples simultaneously. Methods Monitoring the detection data by utilizing the center line of the single value control chart and the moving range control chart, an upper warning limit, a lower warning limit, an upper control limit and a lower control limit, standard error and data point inside and outside the boundary of the range control chart are used to monitor and evaluate the laboratory detection process, and the status of the personnel, instruments and reagents in the experimental detection process is judged. Results By observing the range of test data and analyzing the distribution characteristics and changes of data, the results showed that single value control chart and moving range control chart could effectively monitor the detection process of Staphylococcus aureus in milk, and the data results were reliable. Conclusion The construction of the quality control chart provides an effective means of food hygiene quality control for laboratory testing of the project, and helps to promote the smooth development of the quality control work in the laboratory testing process.
