Maggots in mushrooms are a common occurrence, often caused by flies and mushroom mosquitoes laying their larvae on the fungi. While the sight of maggots may be unappetizing, the good news is that they are generally not dangerous to human health. In fact, the FDA allows for a certain level of maggots in canned mushrooms, with an average of less than 20 maggots per 100 grams, less than 5 of which can exceed 2 millimeters in length. However, it is important to exercise caution as maggots can carry diseases if they have been exposed to rotting plant or animal matter. Additionally, poor heat treatment of mushrooms with maggots can lead to health issues such as helminthiasis. While the presence of maggots in mushrooms may be unpleasant, proper cleaning, processing, and cooking techniques can help ensure they are safe for consumption.

What You'll Learn
Maggots are safe to eat, but can carry diseases
Maggots are considered safe to eat, but they can carry diseases. They are the legless larval stage of the common fly, and while they can be a good source of protein, they can bear diseases if they have been exposed to rotting plant or animal flesh. Poor heat treatment of mushrooms with maggots can lead to helminthiasis in humans. Maggots can also carry bacteria that can cause food poisoning, and their feces can contain dangerous bacteria.
The presence of maggots in mushrooms is often due to the larvae of flies and mushroom mosquitoes. The insects lay their eggs in the mushrooms, and the resulting maggots can become carriers of spores, aiding in the spread of mycelium. While the worms themselves do not make the mushrooms poisonous, it is recommended to discard old, wormy mushrooms due to the potential presence of harmful substances.
To reduce the risk of consuming maggots, it is advisable to harvest mushrooms promptly and cook them immediately. Cooking kills any bugs present, and blanching and dehydrating mushrooms can also help eliminate them. Soaking mushrooms in saltwater before cooking can cause the critters to float to the top, making them easier to remove.
While the idea of consuming maggots may be unappealing, it is important to note that the presence of insects and other contaminants in our food is not uncommon. The FDA acknowledges this by setting acceptable levels of "natural contaminants" in various food products, including canned mushrooms. These regulations are based on economic grounds, recognizing that it is challenging to produce, harvest, or process raw products entirely free of non-hazardous and naturally occurring defects.
In conclusion, while maggots may be safe to eat in terms of immediate health risks, they can carry diseases and bacteria that can cause food poisoning. Proper food handling and cooking techniques are crucial to minimizing these risks.

Worms in mushrooms are not dangerous to human health
That being said, the worms themselves can be a nuisance, and no one will enjoy finding a fried worm on their plate. Experienced mushroom pickers know how to avoid this. There are ways to process wormy mushrooms and make them edible. The main thing is that the mushroom is not rotten. If the mushroom is old and wormy, it should be discarded, not because it is wormy, but because it is old. Old mushrooms contain many harmful substances.
To avoid worms in mushrooms, it is important to harvest the mushrooms quickly. If left too long, the eggs will hatch and the maggots will grow. Cooking the mushrooms kills the bugs, but if you want to remove the bugs before cooking, you can soak the mushrooms in saltwater, which causes the bugs to float to the top of the bowl. Alternatively, you can dehydrate the mushrooms after blanching them to kill the bugs.

Worms do not make mushrooms poisonous
Worms in mushrooms are not dangerous to human health and do not make the mushrooms poisonous. However, the presence of worms in mushrooms is considered unpleasant and unappetizing, and it is generally recommended to discard old wormy mushrooms due to the potential for harmful substances. Thoroughly treating wormy mushrooms with saltwater or drying them before cooking can make them safe to consume.
Mushrooms become wormy when larvae are laid on them by insects such as flies, mushroom mosquitoes, and clicker beetles. These worms can become carriers of spores, aiding in the spread of mycelium. While the worms themselves do not make the mushrooms poisonous, poor heat treatment of wormy mushrooms can introduce the risk of helminthiasis, a disease caused by parasites.
It is important to note that some mushrooms, such as oyster mushrooms, are carnivorous and actively poison and paralyze nematodes (roundworms) to consume them. However, this is not caused by the presence of worms but by the toxic properties of certain mushrooms.
In terms of food safety regulations, the presence of insects and their parts in food, including maggots, is generally considered acceptable up to certain limits. The FDA, for example, allows for a certain number of maggots and mites in canned mushrooms, considering the issue more aesthetic or "offensive to the senses" rather than a health hazard.
Overall, while the presence of worms in mushrooms is undesirable, it does not render the mushrooms poisonous. Proper treatment and cooking techniques can make wormy mushrooms safe for consumption, although it is generally recommended to prioritize fresh and worm-free mushrooms whenever possible.

Canned mushrooms may contain up to 20 maggots per 100 grams
Maggots in mushrooms are generally considered harmless to human health and are safe to eat. However, they can be carriers of spores and diseases if exposed to rotting plant or animal matter. The presence of maggots in mushrooms is often due to the larvae of flies, mushroom mosquitoes, and clicker beetles, which are attracted to dry and sunny weather. While the worms themselves do not make the mushrooms poisonous, poor heat treatment can introduce the risk of helminthiasis.
The occurrence of maggots in mushrooms is a natural phenomenon, and it is challenging to find mushrooms completely free of insects or their larvae. Proper cleaning, processing, and cooking techniques can help mitigate their presence. Soaking mushrooms in saltwater before cooking is a common method to remove maggots, as they tend to float to the top. Additionally, dehydrating or blanching mushrooms can kill any bugs or larvae present.
While the sight of maggots in food can be unsettling, it is important to recognize that we unknowingly consume a significant number of insects and their parts in various food products. The FDA has established acceptable levels of "natural contaminants," including bugs, mold, rodent hairs, and maggots, in our food supply. These levels vary across different food products and are based on economic and practical considerations.
It is worth noting that while maggots in mushrooms may be safe to consume, it is essential to exercise caution with rotting mushrooms. Consuming rotting mushrooms can lead to food poisoning due to the presence of harmful bacteria. Therefore, it is recommended to discard old, rotten, or decomposing mushrooms and prioritize fresh, properly stored mushrooms for consumption.

Maggots are a good source of protein
Maggots are the legless larval stage of the common fly. They are often found in canned mushrooms, and while they may be safe to eat, they are not very appetising. However, they are a good source of protein and can be used as food for exotic pets.
The United Nations encourages the use of insects to fulfil the planet's protein needs. Maggots, specifically black soldier fly larvae, can transform organic waste into high-quality protein. In one year, a single acre of black soldier fly larvae can produce more protein than 3,000 acres of cattle or 130 acres of soybeans. They can efficiently use food waste, eating twice their weight in about four hours.
Maggot farms are becoming a burgeoning industry, with the potential to revolutionise the way we feed the world. Companies like Symton BSF harvest and sell black soldier fly larvae as food for exotic pets and animal feed. AgriProtein, another company in this industry, uses food waste to attract flies, which then lay hundreds of millions of eggs daily. They plan to build 100 more facilities in the US, Asia, and the Middle East by 2024.
While maggots are a good source of protein, the idea of consuming them may be unappealing to many people. However, approximately 2 billion people worldwide routinely eat insects, and the global edible insects market is projected to exceed $522 million by 2023. Finland, the Netherlands, Britain, Belgium, Australia, and Denmark have already started allowing insects to be raised and marketed for human consumption.
