Unsuspected diversity and multiple origins of the frog legs imported to Switzerland for human consumption, as determined by DNA barcoding and morphology.

ABSTRACT: The frog leg industry relies on a global, largely underregulated market with potentially important ecological impact such as the uncontrolled harvest of declining wild populations and the introduction of invasive species. Here, we inferred the taxonomic nature and geographic origins of frog legs imported to Switzerland by DNA barcoding. Out of 34 samples, we retrieved eight distinct lineages attributed to five species from four genera, namely Hoplobatrachus rugulosus from Vietnam, Fejervarya cancrivora from Indonesia (invasive on several Pacific islands), two phylogeographic lineages of Limnonectes macrodon from Western and Central Java, L. kadarsani from eastern Indonesia, and three phylogeographic lineages of Pelophylax ridibundus from northern and central southern Turkey (invasive in We
