Many Asian cultures have included frog legsin their diets for centuries or at least until they have run out of frogs. But themost famous frog-eaters, and the people who inspired frog-eating in Europe andthe United States are the French. By 1977 the French government, so concernedabout the scarcity of its native frog, banned commercial hunting of its ownamphibians*. So the French turned to India and Bangladesh for frogs.As happened in France, American frog-leg fanciers and restaurants also turnedincreasingly to frozen imports. According to figures collected from governmentagencies, the United States imported more than 6.5 million pounds of frozen frogmeat each year between 1981 and 1984.So many frozen frog legs were exported from India to Europe and the UnitedStates. One of the attractions of Indian frogs, apart from the fact that they havebigger legs than French frogs, was the price. In London, a pound of frozen frogslegs from India cost about 1.75, compared with 3.75 for the French variety.Indian scientists have described as disastrous the rate at which frogs aredisappearing from the rice fields and wetlands, where they protect crops bydevouring* damaging insects.Since the India and Bangladesh frog-export bans, Indonesia has become themajor exporter of frog legs to the United States and Europe.

Frogs are nearly impossible tofarm economically in the countries where frogs are commercially harvested fromthe wild.KeyA.1. Many Asian cultures have included frog legs in their diets forcenturies.2.
