First steps for the squeamish
“We are not saying that people should be eating bugs,” said Eva Muller, Director of FAO’s Forest Economic Policy and Products Division, which co-authored “Edible insects: Future prospects for food and feed security”.
“We are saying that insects are just one resource provided by forests, and insects are pretty much untapped for their potential for food, and especially for feed,” Muller explained.
Farming insects sustainably could help avoid over-harvesting, which could affect more prized species. Some species, such as meal worms, are already produced at commercial levels, since they are used in niche markets such as pet food, for zoos and in recreational fishing.
If production were to be further automated, this would eventually bring costs down to a level where industry would profit from substituting fishmeal, for example, with insect meal in livestock feed. The advantage would be an increase in fish supplies available for human consumption. (via FAO Media Centre: Forest products critical to fight hunger - including insects)
