Characterization of antibiotic resistance gene (ARG) and mobile genetic elements (MGEs) in the 18 ready-to-eat (RTE) samples. (a) Broad-spectrum quantitative profile of ARG types (copy of ARG per copy of 16S rRNA gene) in the 18 samples. (b) Composition of ARG types in the 18 samples. (c) Comparison of the relative abundance of the antibiotic resistance genes in RTE meat, RTE vegetables and RTE fruit. Relative abundance refers to the proportion of the antibiotic resistance genes in the total genes in each type of RTE food samples. The line and the square in the diamond boxes denote the median and mean, respectively. The samples are shown as dots on the left. RTE meat: n = 8; RTE vegetables: n = 7; RTE fruit: n = 3. (d) The relative abundance of MGEs including integrons, plasmids and transposons in the 18 samples.
