Why Bugs Must Be a Bigger Part of the Human Food Chain
They’re fine for snacking, but insect protein has its greatest potential as nutrient-rich, climate-friendly livestock feed.
The European Union’s landmark decision last week to approve insects for human consumption was a victory for grubs and maggots — and people — the world over. The approval confers a kind of dignity to the lowly, protein-rich microbeasts that we foolishly dismiss as pests, and delivers a clear signal that the insect proteins industry is poised for significant growth. Above all, it paves the way for an alternative protein source that should play a critical role in feeding a hotter, more populous world.
Before this triggers your gag reflex, let’s be clear: For most consumers, the EU decision won’t translate to bugs in your burgers and mealworms in your macaroni. Yes, insects will play a far more integral role in human food systems going forward, but they won’t likely be a direct form of protein. Instead, they’re becoming an increasingly valuable indirect food source — a feedstock for poultry, farmed fish, pork and beef which are currently fattened on environmentally costly soy and corn feeds.
Humans have been consuming edible insects — from crickets and grasshoppers to fire ants and termites — since before the dawn of civilization, and 80% of the world’s population throughout Asia, Africa and Latin America, continues to eat bugs today. But U.S. consumers have been slow on the uptake, even as the U.S. Food and Drug Administration approved insects for human consumption years ago. A niche market has emerged with snack foods such as Chirp Chips and Exo protein bars. And when the FDA approved insects for pet foods earlier this year, brands including Purina began sourcing bugs for their products.
But the single biggest opportunity lies further down the food chain — as a game-changing ingredient in livestock feed. President Joe Biden’s FDA should make the necessary regulatory changes to clear the way for increased insect supply to animal feed markets.
In 2020, global investments in insect protein nearly doubled to about $475 million and analysts expect the market to exceed $4.1 billion in the next five years. A recent Rabobank report predicts that the 10,000 metric tons of insects currently farmed per year will soar to 500,000 metric tons annually by 2030.
The animal feed industry, meanwhile, is vastly bigger — expected to reach $460 billion by 2026, up from $345 billion in 2020. This sector relies heavily on water and carbon-intensive farming of grains at a time when the cost of agrochemical inputs are climbing and freshwater resources are becoming increasingly unreliable. Globally, animal farms consume more than a third of the world’s total grain production. In the U.S. the share is closer to half. Insect-based animal feeds could be this industry’s best shot at building climate resilience, while also helping to manage a food waste crisis.
The environmental benefits of insect proteins both for human and animal consumption are astounding. Black soldier fly larvae, in particular, hold promise: Known in the industry by the acronym BSFL, these infant bugs serve as high-quality chicken and fish feed and require 1,000 times less land per unit of protein produced compared to soy production, between 50 and 100 times less water, and zero agrochemical inputs.
BSFL have a notable advantage in that they are fed with our food waste, which we rampantly produce, especially in the U.S. Every pound of larvae can munch through 10 pounds of methane-emitting food scraps, playing a significant role in keeping the organic waste out of landfills and reclaiming those nutrients so they can reenter the food chain. Moreover, the larvae produce a valuable byproduct: their excrement is a fertilizer rich with nitrogen and microorganisms, capable of restoring soil quality and enhancing its carbon storage capacity.
Yet insect proteins remain a tiny fraction of the total animal-feed market, in large part because of cost: While a unit of poultry feed costs several hundred dollars and fish feed costs about $1,000, insect feeds can cost more than $2,000. As the industry scales up, these costs will rapidly decline, but the FDA must make key regulatory changes within the Association of American Feed Control Officials to help the industry expand.
