Almost every food you eat contains some amount of insect material. The FDA actually publishes allowable limits for insect fragments in common grocery items, from flour to canned spinach to coffee. Beyond those unavoidable traces, some foods contain insect-derived ingredients on purpose, and a few, like figs, come with a built-in biological story most people never hear about.
The FDA Allows Insects in Your Food
Growing, harvesting, and processing food at scale makes it impossible to keep every last bug out. Rather than demanding zero insects (which no manufacturer could achieve), the FDA sets “defect action levels” that define how many insect parts a food can contain before regulators step in. Below those thresholds, the food is considered perfectly safe to sell and eat.
Some of the specific limits are eye-opening:
- Flour: Up to 75 insect fragments per 50 grams. The rice weevil is one of the most common culprits. A single adult weevil ground up during milling produces roughly 27 fragments, so it doesn’t take many bugs to reach that number.
- Canned or frozen spinach: Up to 50 aphids, thrips, or mites per 100 grams before the FDA considers it a violation.
- Hops: Up to 2,500 aphids per 10 grams. Hops grow outdoors and attract enormous numbers of tiny insects, which means your beer has a long history with aphids.
- Coffee: Pre-ground coffee picks up insect fragments during harvesting and processing in tropical environments. Roasting and grinding destroys any health concern, but the fragments are there.
These thresholds exist because the contamination is harmless. The fragments are thoroughly processed, cooked, or roasted by the time they reach your cup or plate. There is no credible evidence that consuming insect parts at these levels poses any toxicity or disease risk.
Insect-Based Food Dyes
If you’ve ever eaten something bright red, pink, or magenta from a package, there’s a decent chance the color came from crushed insects. Carmine, also labeled as “cochineal extract,” is a red pigment made from cochineal scale insects, tiny creatures that live on cactus plants in Central and South America. The bugs are dried and processed to extract carminic acid, which produces a vivid, stable red.
Carmine shows up in yogurt, candy, fruit drinks, ice cream, and cosmetics. Since 2011, the FDA has required manufacturers to list “cochineal extract” or “carmine” by name on food and cosmetic labels, so you can spot it if you’re looking. Before that rule, it could hide behind vague terms like “artificial color” or “color added.” On European labels, it appears as E120.
Shellac on Your Candy and Fruit
The shiny coating on jelly beans, chocolate-covered candies, and some ice cream cones comes from shellac, a resin produced by the female lac bug in India. The insect attaches to tree branches, sucks sap, and secretes a sticky coating around itself. That resin is harvested, refined, and sold to the food industry under the name “confectioner’s glaze.” It takes roughly 100,000 lac bugs to produce a single pound of the raw resin.
Shellac isn’t limited to candy. Citrus fruits and avocados are sometimes coated with it to add shine and extend shelf life. If a lemon or orange looks unusually glossy at the grocery store, shellac or a similar wax coating is likely the reason.
Figs and the Wasps Inside Them
Figs are one of the few foods where a whole insect enters the fruit as a natural part of how it grows. Figs aren’t pollinated by bees or wind. Instead, each species of fig tree relies on its own specific species of tiny wasp.
When a fig is ready to be pollinated, it releases a scent that attracts a female wasp. She squeezes through a tiny opening at the bottom of the fig, and the passage is so narrow that she loses her wings and parts of her antennae on the way in. Once inside, she lays eggs in some of the fig’s flowers and pollinates the rest with pollen she carried from the fig where she was born. Then she dies inside the fruit.
Her offspring hatch, mate inside the fig, and the new females fly out carrying pollen to repeat the cycle. The males, which are wingless and never leave, also die inside the fig. By the time a fig ripens and reaches your plate, the wasp’s body has been broken down by enzymes the fig produces. You’re not biting into recognizable insect parts, but the wasp’s organic material has been absorbed into the fruit. This is true of wild figs and many cultivated varieties, though some commercial fig types are grown without wasp pollination.
Pantry Pests in Grains and Flour
If you’ve ever opened a bag of flour or rice and found tiny beetles or worms, you’ve met pantry pests. The rice weevil is one of the most studied. Female weevils lay eggs inside individual grain kernels, and the larvae develop hidden inside the seed, making them nearly impossible to detect before milling. Research on rice weevils found that immature larvae produce fewer than one fragment each when ground, while a single adult produces about 27 fragments, enough to show up clearly in quality testing.
Other common pantry invaders include Indian meal moths (which leave webbing in cereal and dried fruit), flour beetles, and grain borers. These insects can infest food at any point from farm storage to your kitchen shelf. Storing flour, rice, and dry goods in airtight containers and keeping your pantry cool and dry reduces the chance of an infestation at home, but some level of insect contamination has already occurred before the product was packaged.
Intentional Insect Foods
Cricket flour, roasted mealworms, and other edible insect products are a growing category in grocery stores and online retailers. Crickets and mealworms are the two most common species sold as food in Western markets, typically ground into powder and added to protein bars, pasta, or baking mixes. Whole roasted crickets are also sold as snacks.
Edible insects are protein-dense, and the global market for them is projected to reach nearly $6 billion by 2032. In much of Asia, Africa, and Latin America, eating insects has never been unusual. Grasshoppers, silkworm pupae, ant larvae, and water beetles are all common ingredients in regional cuisines. The Western market is newer but expanding quickly, driven by the environmental argument that raising insects requires far less land, water, and feed than conventional livestock.
How to Spot Insect Ingredients on Labels
If you want to avoid insect-derived ingredients, the two main ones to watch for are carmine (or cochineal extract) and confectioner’s glaze (shellac). Both are required to appear by name on U.S. food labels. Carmine is the red dye, confectioner’s glaze is the shiny coating. On imported products, look for E120 (carmine) or E904 (shellac).
For the unavoidable insect fragments in flour, coffee, canned vegetables, and spices, there’s no way to eliminate them entirely. They aren’t listed on labels because they aren’t ingredients. They’re a natural consequence of large-scale food production, present in amounts too small to see and too thoroughly processed to affect your health.
