Would you like them with garlic and butter?

They are as big as the palm of a human hand. weigh almost a kilo and are a West African delicacy when peppered, then sautéed with onions and tomatoes, garlic and chilies. But not something that is likely to be on US menus anytime soon.
A shipment of 67 of these Archachatina marginata, or banana rasp snails, were recently seized by customs inspectors at Los Angelese airport after arriving from Nigeria. The officials described the snails as "highly invasive, voracious pests" that eat paint and stucco off houses and can munch their way through 500 plant species, if they can't find fruits and vegetables.
They were consigned to an incinerator rather than a cooking pot.
