There are regulatory restrictions on selling insect meal as commercial livestock feed in many countries, including the USA, particularly if raised on animal wastes, such as manure, due to possible pathogens or contaminants. Crop residues and waste from bioethanol are suitable feedstocks to rear invertebrates. The Canadian company Enterra feeds pre-consumer recycled food (food waste from local farms, food processors, and grocery stores) to BSF larvae but no animal waste or meat [84]. The Canadian Food Inspection Agency has approved Enterra Whole Dried Larvae as a feed ingredient for aquaculture and poultry. In the USA, the Association of American Feed Control Officials allows this feed for salmonids [85]. Small producers may be able to raise invertebrates on their own farms and feed them to their animals.
