*2.6. Statistical Analysis*

Data acquisition was performed using TraceFinder software (version number: 4.1.31.9, Thermo Fisher Scientific, Waltham, MA, USA). Three parallels were carried out for each experiment, and the data were expressed as the mean ± standard deviation. Statistical analysis was performed using SAS software (version number: 6.2.9200, SAS Institute Inc., Cary, NC, USA), and the significant influence of different cooking methods or times on the concentrations of amphenicols and metabolites in livestock and poultry meat blocks were analyzed by one-way analysis of variance (ANOVA) and Duncan's multiple comparisons. A *p* < 0.05 was considered to be statistically significant. The figures were plotted using OriginPro 2022 software (OriginLab, Northampton, MA, USA).
