Statistics on imports and exports of frog legs are sparse as few countries keep track of the amount of meat harvested and consumed domestically.
According to UN figures, global trade has increased in the past 20 years. France - not surprisingly - and the US are the two largest importers; with France importing between 2500 and 4000 tonnes of frog meat each year since 1995.
....Even top French chefs may be unaware of where their frogs are coming from. Bruno Stril, teaching chef at the Cordon Bleu school in Paris, France, is unsure where his suppliers source their frog legs. "I would like for them to come from France," he says. But he expects that most of the meat comes from other countries.
Stril is on the right track. Indonesia is the world's largest exporter of frog meat, exporting more than 5000 tonnes of frog meat each year, mostly to France, Belgium and Luxemburg.
...European kitchens initially found their own supplies in the surrounding countryside, but the fact that they are now importing from Asia suggests local populations were over-harvested.
This...could be a sign that frog populations, like many fish populations, will be harvested to near extinction.
