Yes, eating ants is safe, and people have been doing it for thousands of years across Africa, Asia, Latin America, and Europe. More than a dozen ant species are regularly consumed worldwide, many of them surprisingly nutritious. That said, there are a few real risks worth knowing about, especially if you’re foraging wild ants rather than buying farmed ones.
Why People Eat Ants
Ants aren’t just a survival food or a novelty. They’re a genuine protein source. Black ants from East Africa (Carebara vidua) contain roughly 41% protein and 48% fat by dry weight, along with meaningful amounts of iron (about 10.7 mg per 100g) and zinc (5.7 mg per 100g). For context, that iron content rivals red meat. They also contain B vitamins, vitamin A, and vitamin E in small amounts.
Different cultures prize different species. In Colombia and Venezuela, leafcutter ants called “hormigas culonas” (big-bottomed ants) are roasted and eaten during their mating season in May and June. In Mexico, the larvae and pupae of Liometopum ants are known as “escamoles,” sometimes called Mexican caviar, and have been a delicacy since Aztec times. In Thailand and Laos, weaver ant larvae and pupae are among the most popular edible insects. Even in Europe, wood ants (Formica rufa) were historically used to flavor spirits in Sweden and to ferment yogurt in Bulgaria. Common black garden ants have a sharp, vinegary taste that some African hunter-gatherer communities use as a seasoning.
The Shellfish Allergy Problem
If you have a shellfish allergy, eating ants is a genuine risk. Crustaceans and insects are closely related on the evolutionary tree, and the protein that triggers most shellfish allergies, tropomyosin, is also found in insects. Your immune system may not distinguish between shrimp and ants. Research from McGill University notes that people with shellfish allergies have “a good chance” of reacting to insects like crickets, mealworms, and by extension, ants. Dust mite allergies involve the same protein, so the same caution applies.
Parasites in Wild Ants
This is probably the most important safety issue for anyone thinking about eating ants they find outdoors. Certain wild ants, particularly those in the Formica genus common across Europe and North America, can carry the larval stage of a parasite called the lancet liver fluke. According to the CDC, when a person swallows an infected ant, the parasite can travel to the bile duct and mature there. Humans aren’t the parasite’s intended host (that would be grazing animals like sheep and cattle), but accidental infections do happen, sometimes from ants contaminating food like unwashed produce.
The fix is straightforward: cooking kills the parasite. Freezing or boiling ants before eating them eliminates this risk. Eating raw wild ants, especially Formica species, is the scenario to avoid.
Pesticides and Urban Ants
Ants foraged from lawns, gardens, or agricultural fields may carry pesticide residues. Research published through the EPA found that common insecticides like neonicotinoids accumulate in ants at concentrations well within the range found in treated plant pollen and nectar. Ants from areas treated with insecticides, herbicides, or fertilizers are not safe to eat. If you’re foraging, stick to areas far from agricultural land, treated lawns, and roadsides.
Formic Acid Won’t Hurt You
Many people worry about formic acid, the chemical some ants spray as a defense. While concentrated formic acid is corrosive and dangerous, the amount in an individual ant is tiny. The UK Health Security Agency describes ant stings as “a source of low-level exposure.” Eating a handful of ants exposes you to negligible quantities. Cooking further breaks down whatever trace amounts are present. This is not a meaningful health concern.
Heavy Metals in Ant Products
One risk that gets less attention: ant powders and supplements can contain lead and arsenic. Analysis of Chinese black ant powder (Polyrhachis vicina, a species sold as a health supplement) found lead at 1.3 mg/kg and arsenic at 0.6 mg/kg. The arsenic level exceeded China’s own safety threshold for health food products. Toxicity testing showed the powder itself is nontoxic in normal amounts, but if you’re taking ant-based supplements regularly, contamination with heavy metals is worth checking for. Buying from reputable sources with third-party testing matters.
How to Prepare Ants Safely
The same food safety principles that apply to any protein apply here. Cook ants thoroughly before eating them. Roasting, frying, and boiling are the most common traditional methods. In Latin America, leafcutter ants are typically roasted or toasted and smoked. In East Africa, black ants are fried, roasted, or eaten raw (though cooking is safer). In parts of Europe, researchers specifically recommend freezing, boiling, or treating ants with alcohol before eating them to kill parasites.
If you’re buying edible ants from a specialty food retailer, they’ve almost certainly been processed and heat-treated already. If you’re foraging your own, avoid any area where pesticides might be present, cook them before eating, and stick to species you can positively identify. The edible insect market was valued at roughly $1.8 billion in 2024 and is growing fast, so commercially raised options are becoming easier to find.
What They Taste Like
Flavor varies by species. Common black garden ants taste sour and vinegary due to their formic acid content. Leafcutter ants have a nutty, bacon-like flavor when roasted. Weaver ant larvae are described as creamy and mild. Escamoles have a buttery texture often compared to cottage cheese. If you’re trying ants for the first time, roasted leafcutter ants or commercially prepared ant products are the most approachable starting point.
