Here's a nice little health tip from the good folk at Reuters:

STORY: In Mexico, earthworms aren't just for tequilas
anymore. Researchers at Mexico's National Polytechnic
Institute recently invented a cookie made out of an
earthworm-based flour in an effort to create a nutritional
snack.
Although earthworms live in and travel through the dirt,
scientific researcher Iliana Mendez insists they don't pose
any danger despite the impression most people have.
"The earthworm is very clean," Mendez said. "It's seen as
dirty because it can be found in trash and organic wastes and it's seen as filthy but really, its skin and its shape do not lend itself to bacteria."
Before grinding the worms into flour, the researchers keep the worms in the laboratory for 15 days feeding them a diet of fruit and vegetables and washing them routinely.
The worms are then killed with a saline solution, dried by
sunlight, ground into flour and mixed with flour to make the cookies.
According to the scientists, the earthworm, also known as lumbricus terrestris, is very high in protein, low in fat, and high in carbohydrates. Eaten by birds in nature, they have also been used as poultry feed by scientists.
Researcher Jose Coral said the animal's nutritional value
initially caught their attention as a possible source for
human food.
"We set about to make flour because they have a high
concentration of protein -- up to a base of 70 percent," Coral said. "We researched what food we would create out of it and what we found to be most convenient was to make a cookie out of worm flour."
According to the scientists, it takes about 200 worms to
make 450 grams of cookies, which makes the chocolate cookies very high in protein.
Researchers said they are also experimenting with making
an anti-wrinkle cream out of earthworms.

Mmmm, yummy! So, how do they taste, TB? :D
