EU allows up to 4 grams of insects per 100 grams of flour

Europe now permits 4 grams of insects per 100 grams of flour

The European Union has authorized the sale of flours treated with larvae of Tenebrio molitor (mealworm), Acheta domesticus (house cricket), Alphitobius diaperinus (lesser mealworm), and Locusta migratoria (migratory locust). The limit is set at 4 grams of insect matter per 100 grams of flour. Published in Spain's Official Gazette (BOE), the regulation mandates declaring these ingredients due to allergy risks, particularly for those allergic to crustaceans and dust mites. This measure has angered part of the population, who see it as a step toward replacing traditional proteins with insects. Their suspicion is well-founded: since the rule was published, not a single brand has admitted to using these flours.

What does the EU regulation say about insect flour?

The list of authorized ingredients is explicit: UV-treated powder from whole Tenebrio molitor larvae (mealworms), partially defatted powder from Acheta domesticus (house crickets), frozen, paste, dried, and powdered forms of Alphitobius diaperinus (lesser mealworms) and Locusta migratoria (migratory locusts) in their frozen, dried, and powdered versions. The rule sets a 4% limit for flours, but this percentage can increase if multiple processed products are combined in one diet.

Labeling is key. Legislation requires informing consumers about allergy risks but does not specify a unique format. This is the loophole: under an E-code or euphemism, consumers won't know what they are eating. Suspicion that it is hidden under additives drives much of the discontent. The rule itself only advises against consumption for those allergic to crustaceans and dust mites, leaving out millions who may be unaware of such sensitivities.

Why do people suspect brands are hiding it?

Since the rule was published, no brand has come forward to state they use these flours. Not one. This fuels the theory that they will be introduced quietly, camouflaged in processed foods, and discovered by consumers when it is too late. The Overton window applied to baking: first 4%, then 5%, and by 2050 insects will dominate the bread loaf.

Some argue that boycotting is the only possible response. Identifying companies that manufacture or sell products with insects and calling for a boycott is being promoted on social media. Others, more skeptical, recall that once all brands use these flours, a boycott will be futile. Some point out that the problem is not the insect itself, but chitin, the toxic polysaccharide in the exoskeleton, which is ingested unavoidably when the whole insect is ground.

The real cost of insect farms

The economic paradox is evident. If the goal is cheaper protein, the numbers don't add up. Insect farms require high investments, maintenance, energy, water, and labor. A kilogram of insect flour costs more than a kilogram of wheat flour. In Spain, 37 insect farms are already operating, all subsidized. The business is not self-sustaining: it needs public money.

This explains why the sector advances despite consumer resistance. Investors have done their calculations. Politicians supporting them have too. Meanwhile, bread remains the cheapest to produce, most subsidized, and most consumed item. It is the perfect terrain to slip in the ingredient unnoticed.

Allergies, boycotts, and the culture war over food

The health argument is the strongest. The regulation acknowledges allergy risks but does not mandate visible labeling. Those allergic to dust mites could suffer reactions without knowing the cause. In severe cases, repeated exposure to an unknown allergen can lead to serious problems. Information is the only defense, and today it is not guaranteed.

Social response ranges from boycotts and online complaints to resignation. Some have stopped eating bread entirely. Others demand clear labels and scannable codes. Some see this as a deeper operation: getting the population used to eating whatever they are given, without questioning. The culture war over food is here. And the battlefield is the bakery counter.

---

The most repeated prediction is that the percentage will rise unnoticed. First 4%, then 5%, and in decades insects will be just another ingredient. If that happens, the boycott will have come too late. But while brands do not declare it and labels do not shout it, distrust will continue to grow. And rightly so.
