In Europe, and particularly in Italy, there is still widespread prejudice against eating insects. Yet around the world, nearly two billion people—almost one-third of the global population—regularly include insects in their diets. Historically, insects have always been part of human nutrition, according to a study by the Food and Agriculture Organization (FAO).
Now, the European Food Safety Authority (EFSA) has stepped in to reassure Europeans. After analyzing the biological and chemical risks of using insects in food and animal feed, EFSA experts concluded that eating insects is not harmful, provided they come from controlled insect farms—a key condition for ensuring hygiene. The experts also highlighted the importance of what insects are fed (the so-called substrate) and the life-cycle stage at which they are harvested.
Which Insects Are Approved for Food and Feed?
EFSA has identified the insect species with the greatest potential for use as food or feed. These include:
- Houseflies (Musca domestica)
- Mealworms (Tenebrio molitor larvae)
- Crickets (Acheta domesticus and Gryllodes sigillatus)
- Silkworms (Bombyx mori)
These species are already being farmed in several EU countries and are considered safe when raised under strict hygiene standards.
Why Edible Insects Are a Sustainable Protein Source
The project “Feeding the Planet with New Sustainable Sources: Edible Insects” was launched to promote insect-based nutrition. Its findings underscore the environmental benefits: insects provide a more efficient source of protein and amino acids than traditional livestock. For the same amount of protein produced, insects consume far less feed, water, and energy, and generate fewer greenhouse gases. They can also be used to decompose organic waste without competing with humans for food.
Environmental Benefits at a Glance
| Resource | Traditional Livestock | Insects |
|---|---|---|
| Feed conversion efficiency | Low | High |
| Water consumption | High | Low |
| Greenhouse gas emissions | High | Low |
| Land use | Extensive | Minimal |
These advantages make edible insects a compelling option for future food security.
The White Paper on Edible Insects
As part of the project, a White Paper on Edible Insects was published. It was presented at Expo 2015 in the Europe Pavilion, with contributions from authoritative experts:
- Maura Calliera (Opera Research Center for Sustainability – Catholic University of Piacenza)
- Ettore Capri (Opera Research Center for Sustainability – Catholic University of Piacenza)
- Mario Colombo (Department of Food, Environmental and Nutritional Sciences – University of Milan)
- Antonia Ricci (Istituto Zooprofilattico delle Venezie)
- Roberto Valvassori (Department of Biotechnology and Life Sciences – University of Insubria)
- Piero Amos Nannini (President of the Fondazione Società Umanitaria)
The White Paper provides comprehensive guidelines for safely integrating insects into the European food chain. It covers farming practices, processing methods, and regulatory frameworks.
Practical Tips for Homeowners
While edible insects are gaining acceptance in the food industry, homeowners may still face unwanted insect infestations.

FAQ
Are edible insects safe to eat?
Yes, according to EFSA, insects from controlled farms are safe for human consumption when raised under proper hygiene conditions. The main risks come from wild insects, which may carry pathogens or toxins.
Which insects are most commonly eaten in Europe?
The most common edible insects in Europe are mealworms, crickets, grasshoppers, and silkworms. These are often sold as whole insects, powders, or protein bars.
Do edible insects taste good?
Many people describe the taste as nutty or earthy, similar to roasted seeds. Crickets have a mild flavor, while mealworms are often compared to almonds. They can be seasoned and cooked in various ways.
Can I farm insects at home?
Yes, small-scale insect farming is possible for personal use. However, you must follow hygiene guidelines to avoid contamination. Commercial farming requires strict regulatory compliance.
Are edible insects environmentally friendly?
Absolutely. Insects require significantly less feed, water, and land than traditional livestock, and they produce fewer greenhouse gases. They are considered a sustainable protein source for the future.
