Mushrooms are a type of fungus that is often grown indoors in carefully controlled environments. However, they can also be foraged from the wild, where they may be subject to various pests and insects. One common issue with mushrooms is the presence of maggots, which can be found in both wild and cultivated mushrooms. Maggots are the larvae of flies, such as the Phorid fly and the Sciarid fly, which lay their eggs in the mushroom's substrate. The larvae then feed on the mushroom tissue, which is similar to animal tissue, and can cause significant damage to the crop. While the presence of maggots in mushrooms may be unappetizing to some, it is important to note that consuming insects is practiced by many people and is not inherently harmful. Proper handling and cooking techniques can help reduce the presence of maggots and ensure food safety.

Maggots in mushrooms are normal, especially in older wildcrafted mushrooms
Maggots in mushrooms are indeed normal, especially in older wildcrafted mushrooms. Mushrooms are a type of fungus that grows in dark, damp places, which also happen to be ideal breeding grounds for flies. Flies are attracted to the scent of mushrooms, and they lay their eggs on or near the mushrooms. The eggs then hatch into maggots, which feed on the mushroom tissue.
While it may be unsettling to find maggots in your mushrooms, it is important to remember that mushroom tissue is similar to animal tissue, and just as flies are attracted to decaying animal flesh, they are also attracted to decaying mushrooms. This is especially true for older, wildcrafted mushrooms that have been damaged or have started to rot.
If you do find maggots in your mushrooms, it is important to take steps to remove them before consuming the mushrooms. One way to do this is to place the mushrooms in a plastic bag and seal it shut, leaving one small corner open. Then, use your mouth or another method to suck out as much air as possible before sealing the bag completely. This will create a vacuum that will kill the maggots. You can also try soaking the mushrooms in salty water, which will encourage the maggots to float to the surface and can then be skimmed off.
It is worth noting that, according to the FDA, it is "impractical to grow, harvest or process raw products that are totally free of non-hazardous, naturally occurring, unavoidable defects". This means that even commercially available mushrooms may contain a certain percentage of "natural contaminants" such as maggots. However, this does not make them unsafe to consume, especially if the mushrooms are cooked, as cooking kills any bacteria or parasites that may be present.
In fact, entomophagy, or the practice of eating insects, is common in many parts of the world, and maggots are considered a good source of protein. So, while it may be unappetizing to think about, consuming maggots along with your mushrooms is generally safe and may even provide some nutritional benefits.

Maggots are decomposers, attracted to decaying mushrooms
Maggots are indeed attracted to decaying mushrooms, as they are decomposers. Mushrooms, being a soft, fleshy fungus, are susceptible to various pests, with the most common and damaging being the sciarid fly, also known as the fungus gnat. These flies lay their eggs in the mushroom, and the resulting maggots feed on the mycelium, stipe, and gills of the mature mushrooms. The maggots are white or orange and can spread throughout a mushroom farm, decimating the crop.
Mushrooms that are left to grow old and decay in the wild are particularly susceptible to maggots. The scent profile of older mushrooms changes, attracting flies and maggots. This is a natural occurrence, and foragers often simply cut out the infested parts of the mushroom and cook the rest.
While the presence of maggots in mushrooms may be unappetizing to some, it is not necessarily harmful. Many people around the world practice entomophagy, or the consumption of insects, and maggots are considered a good source of protein. The FDA also condones a certain percentage of "natural contaminants," including bugs, in our food supply.
To prevent maggots from infesting mushrooms, growers can use yellow sticky fly traps to catch adult flies and break their breeding cycle. Organic sprays containing pyrethrum can also be used, although these are more effective for management before an infestation occurs. Foragers can also soak their mushrooms in salty water to encourage maggots to leave the fungus.

Maggots in mushrooms are harmless to humans and even edible
Maggots found in mushrooms are generally harmless to humans and can even be eaten. While they may be unappetizing to some, the presence of maggots in mushrooms is not uncommon, especially in older or wild mushrooms.
Mushrooms provide an ideal environment for maggots, as their tissue is similar to animal tissue, making it possible for maggots to feed and thrive. Maggots are attracted to the scent of mushrooms, and they can quickly infest a crop, leading to significant damage if left unchecked.
To prevent maggot infestation, mushroom growers must implement strict pest control measures. However, even with these measures, it can be challenging to keep maggots and other pests at bay. As a result, it is not unusual for consumers to find maggots in store-bought or foraged mushrooms.
While the sight of maggots in mushrooms can be off-putting, it is important to note that they do not pose a significant health risk. In fact, according to the U.S. Food and Drug Administration (FDA), the presence of a limited number of maggots in food products, including mushrooms, is considered acceptable. The FDA classifies such occurrences as "natural contaminants" or "defects" that are ""offensive to the senses" but do not present any health hazards.
Additionally, maggots themselves are edible and are consumed by people practicing entomophagy (the practice of eating insects). When cooked, maggots can be a good source of protein and are said to have a nutty flavor. However, it is essential to ensure that the maggots are cooked before consumption to kill any potential bacteria or parasites they may be carrying.

Maggots can be removed from mushrooms by soaking them in saltwater
Maggots in mushrooms are a common occurrence, especially in older, decaying mushrooms. While the idea of maggots in your mushrooms may be unappealing, it is important to note that the FDA considers insects in food to be "natural contaminants" and allows for a certain percentage of them in our food supply. In fact, it is estimated that people unknowingly ingest one to two pounds of flies, maggots, and mites each year.
If you are uncomfortable with the idea of consuming maggots, there are several methods you can use to remove them from mushrooms, including soaking them in saltwater. Here is a step-by-step guide on how to do this:
Step 1: Prepare the Saltwater Solution
Dissolve a handful or two of salt in a large bowl of water. The amount of salt you use will depend on the volume of water, but it is recommended to use no more than a couple of tablespoons of salt per few cups of water to avoid making the mushrooms too salty.
Step 2: Soak the Mushrooms
Place the mushrooms in the saltwater solution and use a heavy pot or plate to weigh them down if necessary. Ensure that the mushrooms are fully immersed in the saltwater. Let the mushrooms soak for at least 20-30 minutes, but no longer than 10 minutes if they are fragile or have pores, as extended soaking may affect their texture.
Step 3: Rinse and Dry the Mushrooms
After soaking, drain the saltwater and rinse the mushrooms thoroughly with clean water. Leave the mushrooms out to dry before use or storage, placing them gill-side down if they are oysters.
Step 4: Inspect and Cook the Mushrooms
Even after soaking, it is possible that some maggots or larvae may remain. Inspect the mushrooms during the cooking process and remove any maggots you spot. Cooking the mushrooms will kill any remaining maggots or larvae, making them safe to consume.
By following these steps, you can effectively remove most maggots from mushrooms and reduce the risk of consuming them. However, it is important to note that some mushrooms, such as fragile varieties or those with pores, may not be suitable for saltwater soaking due to potential changes in texture. In such cases, alternative methods of maggot removal, such as direct insecticide application or blanching before dehydration, may be more appropriate.

Phorid flies and Sciarid flies are common pests that infest mushrooms
Mushrooms are susceptible to infestations by various insects, including flies and maggots. Phorid flies and Sciarid flies are common pests that infest mushrooms.
Phorid flies, also known as humpback flies, scuttle flies, or coffin flies, are tiny insects, typically measuring around 3 mm in length. They are found worldwide, with the greatest variety of species in the tropics. Phorid flies are attracted to decaying organic matter and are often found in unsanitary places like drain pipes, food sources, and waste piles. The Megaselia halterata, or mushroom phorid, is a specific species known to infest mushroom cultures. While they do not directly damage the mushrooms, they are efficient vectors of dry mould (Lecanicillium fungicola). Phorid flies have a relatively short life cycle, ranging from 14 to 37 days, with females laying up to 750 eggs during their lifetime.
Sciarid flies, on the other hand, are also common pests of mushrooms, especially in controlled environments like mushroom houses and greenhouses. The larvae of these flies, often referred to as fungus gnats, tunnel into the stalks of mushrooms, causing feeding damage that can result in mushrooms becoming brown and leathery. Sciarid flies thrive in warm and moist conditions, which facilitate their rapid development. The adult flies do not cause direct damage to plants but can be a nuisance when flying around indoors.
To control Phorid fly infestations, it is crucial to locate and remove or clean the food source that attracts them. Biological control methods, such as using predatory mites or pathogenic nematodes, can also be employed to manage both Phorid and Sciarid fly infestations.
While the presence of insects in mushrooms may be unappealing to some, it is important to note that the FDA considers these contaminants to be primarily "aesthetic" or "offensive to the senses" rather than hazardous to human health.
