Marieke Callis sifts droppings from a container filled with Buffalo worms at an insect farm in Ermelo January 12, 2011. The Callis family started the insect farm 30 years ago to grow insects to be used as food for monkeys, birds, reptiles or animals in general but would like to expand their business to grow insects for human use. Quiche with mealworms, roasted grasshoppers and chocolate pralines with buffalo worms do not make ideal menu for housewarming parties, but in a few decades could be on dinner tables in many European countries as scientists seek ways to replace expensive meat.
