Protein from insects is expected to be approved by the EU for use as feed for pigs and chickens over the next six months, according to a leading expert and advisor on edible insects to the United Nations’ Food & Agriculture Organisation.

If the costs of insect animal feedstock could be brought down by automated production techniques, it would become a serious alternative to products such as soy feed protein for chicken and pigs, said Professor Arnold van Huis, a tropical entomologist from Wageningen University. It could also be used as a replacement for fishmeal in aquaculture as fish stocks and fish feed becomes increasingly scarce and expensive.

Speaking at the Food Vision conference in Cannes earlier this week (Wednesday April 2), van Huis also noted that for technical reasons, insects provided a better feedstock for fish than plant-based protein alternatives.

Van Huis suggested that the use of insects as animal feed would prove more acceptable in the western world in the short term than as a protein for human consumption. But he argued for far greater consumption of insects in the human diet across the globe as obstacles – both cost and regulatory – were overcome.

Automated production techniques

He announced that the European Commission was just about to approve the use of insects for feeding to pigs and chickens across the EU. And he added that emerging automated production techniques would bring down costs significantly.

“DG Sanco is really thinking about it and we believe that very soon it will be allowed to be fed, not to ruminants, but to pigs and sheep,”​ said van Huis.

Unpublished studies also showed that at least 50% of fishmeal could be replaced by insect meal in aquaculture, he added. But he pointed out that other legislative barriers would need to be overcome before this could happen. “Insects are also animals, so we will need a slaughterhouse for insects,” ​he said.

Already several species of insects were being grown on waste around the world, said van Huis. “You can grow these insects on manure and end up with a high protein product,” ​he said. “Since June 1 last year it’s allowed to be used in aquaculture. That’s quite important because aquaculture is growing by about  9% a year.

Looking for alternatives

Van Huis added: “Half of all our fish is more or less cultured right now so they normally use fishmeal as feed, but because of over exploitation that is getting extremely scarce and expensive so they are really looking for alternatives.

“For pigs and poultry it is not allowed yet in the EU but we expect probably within half a year that this will be allowed also.”

One of the insect varieties that could be used for aquaculture is a house fly, which is already being produced on a large scale by a South African company in a product known as MagMeal, said van Huis. “The advantage is it grows in just three days,”​ he said. “But if you really want to promote it, we have to farm it.”

The main obstacle to its more widespread use as a feedstock at the moment is the cost. Because production is very labour intensive, the cost works out at about euro 4.75/kg (£3.92/kg), said van Huis. “So this has to be mechanised.”

The price would need to be reduced to about euro 1/kg (£0.83/kg) to be competitive, he said. “A number of companies in Europe have already sorted out how to automate the whole system, so I think it can be competitive​.” ​One idea could be to grow the insects on food waste, he added.

Aren't we (again) entangling our supply chains without knowing and understanding completly the consequences? Haven't we learned anything on the Mad Cow "thing"?

Price Structure

Posted by Next Millennium Farms,

What an exciting article!
I applaud Europe for seemingly eliminating barriers and encouraging progress in this very important feed and environmental food commodity.
That said, I do not think the price comparison is fair. (1-kg). Traditional fish feed or animal feed, is primarily grain based, or has other inputs that could be less healthy, then a vegetable based or other non grain based input feed. These organic and non grain based feed inputs produce truly organic feed and therefore a truly organic protein source, with incredible nutritional as well as environmental advantages. When fed to fish and or chicken and or other livestock, we finally have, empirically - an organic fish or chicken etc.
Between the incredible health advantages coupled with the environmental advantages, well, there really is no objective reason to not embrace this awesome opportunity.
