I get asked about this more than you'd expect. "Can people eat these things?" The short answer is that BSFL are genuinely nutritious, they're approved for human consumption in the European Union, and they are not currently FDA-approved for human consumption in the United States. That distinction matters a lot, so let's walk through it.
The Nutritional Case
On paper, BSFL are impressive. Roughly 40 to 50% crude protein by dry weight, up to 35% lipids, and an amino acid profile similar to fishmeal. They carry more zinc and iron than lean meat, and their calcium content can exceed what you'd find in milk. The fatty acid profile includes lauric acid, which has documented antimicrobial properties. Chitin from the exoskeletons may have beneficial effects on gut health and immune function, though that research is still developing.
If you're comparing BSFL to other protein sources purely on nutrition, they hold up well. The protein density per unit of environmental input, water, land, feed, is dramatically better than conventional livestock. No antibiotics, no growth hormones, minimal water requirements, and they eat waste streams that would otherwise go to landfill.
Regulatory Reality
The EU authorized BSFL as a novel food for human consumption in January 2022 under Commission Implementing Regulation (EU) 2021/1975. That means processed BSFL products can be legally sold for human consumption in EU member states.
In the United States, BSFL are approved for use in animal feed but have not received FDA approval for human consumption. That's where we are right now. There's no timeline for when or if that changes. If you're in the US, legally, BSFL are animal feed, not people food.
The Cultural Context
Entomophagy, eating insects, isn't new. Over 2 billion people globally consume insects as part of traditional diets. Fried insects are common street food in Thailand. Chapulines, grasshoppers, are a staple in Mexican cuisine. Across Africa and Asia, insect consumption has thousands of years of history. The Western aversion to eating bugs is the cultural outlier, not the norm.
That said, BSFL specifically are relatively new to the human food conversation. Most of the insect-as-food industry has focused on crickets and mealworms, which have had more consumer-facing development. BSFL are catching up, primarily because their production economics and nutritional profile are hard to beat.
What Products Exist
In markets where it's legal, BSFL show up as protein powder for smoothies and baking, dried and roasted as snacks (often compared to roasted nuts in texture), ground into flour for pasta and protein bars, and as extracted oil for cooking or supplementation. The processing removes most of the "bug factor" that makes Western consumers squeamish, though obviously the whole roasted larvae are still clearly larvae.
Where Blue Grub Farms Fits
We're an animal feed and soil amendment operation. Our Golden Grubbies dried larvae and Frassquatch fertilizer are our products. We don't sell BSFL for human consumption, and we won't until and unless US regulations allow it. But I follow the research and the regulatory landscape closely because the potential is real.
If you're raising BSFL and someone asks whether they can eat them, the answer is: nutritionally, yes, they're excellent. Legally in the US, no, not yet. And practically, the larvae you're raising for your chickens are the same animal that two billion people would recognize as food. Whether Western markets get there is a question of regulation and culture, not biology.
