Glyphosate is a widely used herbicide that has been detected in various food products, including mushrooms. It is used in agriculture and private gardens and has been found to affect belowground interactions between earthworms and symbiotic mycorrhizal fungi. Despite its effectiveness and low cost, there are concerns about its presence in soils, waters, and food products, with some countries imposing restrictions on its use. Studies have shown that glyphosate residues can be found in mushrooms, with varying levels of prevalence and potential health risks. This has raised questions about the impact of glyphosate on mushroom growth and the environment.

Glyphosate is a herbicide used in agriculture and private gardens
Glyphosate is absorbed through foliage and, to a lesser extent, through roots. It inhibits EPSP synthase, an enzyme involved in the synthesis of three aromatic amino acids: tyrosine, tryptophan, and phenylalanine. This makes it effective only on actively growing plants and not as a pre-emergence herbicide. Glyphosate is often used in conjunction with selective herbicides and traditional weed eradication methods such as mulching to achieve optimal results.
The widespread use of glyphosate has raised concerns about its potential side effects on non-target organisms and the environment. Studies have shown that glyphosate affects belowground interactions between earthworms and symbiotic mycorrhizal fungi, which are important components in temperate ecosystems, influencing nutrient cycling and overall ecosystem functioning. In addition, glyphosate residues have been detected in crop plants during the growing season following glyphosate treatment, indicating its persistence in the environment.
Despite these concerns, regulatory agencies in the United States, Canada, Japan, Australia, and the European Union have evaluated animal and human studies and determined that glyphosate is not likely to be carcinogenic. The U.S. Environmental Protection Agency (EPA) has also concluded that glyphosate does not pose risks to human health when used in accordance with its current label. However, the potential ecological risks to non-target organisms, primarily through spray drift, have been acknowledged.

Mushrooms grown in wheat straw substrate may contain glyphosate
Glyphosate is the most commonly used herbicide worldwide. Its use has resulted in the contamination of soils and waters. It is applied to agricultural and non-agricultural lands, including ruderal, industrial, and urban areas. Wheat is typically sprayed with glyphosate before harvest, and mushrooms are often grown in wheat straw substrate. Therefore, mushrooms grown in wheat straw substrate may contain glyphosate residues.
A person gardening organically expressed concern about the potential presence of glyphosate in their compost, which included spent mushroom substrate. They worried that wheat straw, a common substrate for mushroom growth, could contain residual glyphosate due to its typical use on wheat pre-harvest. This concern highlights the possibility of glyphosate contamination in mushrooms grown in wheat straw substrate.
While mushrooms are known for their soil remediation capabilities, it is unclear if they can break down glyphosate. Some studies have focused on the ability of certain fungi, such as Purpureocillium lilacinum, to tolerate, utilise, and degrade glyphosate. P. lilacinum has shown the potential to degrade glyphosate significantly (up to 80%) without exhibiting negative effects on growth. However, more research is needed to understand if mushrooms can effectively remediate glyphosate in compost or mushroom substrates.
The potential presence of glyphosate in mushrooms grown in wheat straw substrate raises concerns about its impact on soil organisms and ecosystems. Studies have shown that glyphosate herbicide affects belowground interactions between earthworms and symbiotic mycorrhizal fungi, influencing nutrient cycling and ecosystem functioning. Additionally, glyphosate has been linked to reduced soil biodiversity and increased plant pathogen spread due to its residues in the soil or water. These findings underscore the importance of further investigating the potential glyphosate content in mushrooms grown in wheat straw substrate.

Glyphosate residues found in mushrooms and other food products
Glyphosate is a chemical compound found in some weed killers used by farmers. It is one of the most widely used herbicides in the world, with its usage having increased 100-fold since the 1970s. The introduction of glyphosate-resistant crops in 1996 further contributed to its widespread application. Due to its environmental persistence, there are growing concerns about the contamination of soils and water sources.
A study from the Environmental Working Group found glyphosate in over 95% of popular oat-based food samples, with cereals targeting children being among the most contaminated food products. Another study analysed 7955 samples of food products from Canadian retail markets between 2015 and 2017, finding detectable glyphosate residues in 42.3% of the samples. Fresh mushrooms were among the food items with detectable glyphosate residues, with two samples being non-compliant.
It is important to note that the presence of glyphosate residues in food products does not necessarily pose a risk to human health. Maximum Residue Limits (MRLs) are set well below levels that could be harmful to consumers. While most glyphosate residues found in food products remain below MRLs, there are still concerns about the long-term health effects, especially in children, who are more susceptible due to increased intake and exposure.
To minimise exposure to glyphosate, consumers can refer to lists of certified Glyphosate Residue Free products or opt for organic produce, which is grown without the use of chemical herbicides or pesticides. Eating an organic diet for just six days has been shown to significantly reduce the amount of glyphosate in the body.

Glyphosate affects belowground interactions between earthworms and fungi
Despite their important roles in ecosystems, there is limited understanding of ecological interactions between earthworms and arbuscular mycorrhizal fungi (AMF). The few studies investigating earthworm-AMF interactions suggest that the response patterns are dependent on the species involved. The effects of glyphosate on earthworms vary from detrimental to no effects, however, the extent of their interaction with other soil organisms affected by glyphosate has never been investigated.
Glyphosate is a widely used herbicide in agriculture and private gardens. In a greenhouse experiment with white clover, researchers investigated the effects of a globally used glyphosate herbicide on interactions between essential soil organisms such as earthworms and AMF. They found that herbicides significantly decreased root mycorrhization, soil AMF spore biomass, vesicles, and propagules. Herbicide application and earthworms increased soil hyphal biomass and reduced soil water infiltration after simulated heavy rainfall.
Studies testing glyphosate effects on AMF show an inhibition of AM fungal spore germination and germ tube growth or reduced mycorrhiza in soil. However, these effects were observed only at concentrations greater than those recommended for field use. Several other reports show no effect of glyphosate on mycorrhiza when applied at recommended doses.
The fate of glyphosate in ecosystems is another aspect that has rarely been investigated. While glyphosate binds strongly to soil minerals, leaching and soil erosion by water or wind can transport glyphosate from land to water environments. Due to the widespread use of glyphosate and its environmental persistence, public concerns about the contamination of soils and water are increasing. Some countries have started to impose restrictions on its use.

Glyphosate is considered less toxic than Roundup for aquatic animals
Glyphosate is a widely used herbicide ingredient that has been detected in aquatic environments, where it can affect non-target organisms. Its action is based on the inhibition of an essential enzyme responsible for the synthesis of amino acids in plants and some microorganisms. Due to its widespread use and environmental persistence, concerns about the contamination of soils and waters are rising, leading some countries to impose restrictions.
One of the main concerns regarding glyphosate is its potential toxicity to aquatic life. Studies have been conducted to determine the acute toxicity of glyphosate and its formulations, such as Roundup, to aquatic animals and invertebrates. These studies have found that glyphosate is consistently less toxic than Roundup for aquatic animals. For example, in a study on the toxicity of glyphosate and Roundup to four aquatic invertebrates and four fishes, it was found that glyphosate was considerably less toxic than Roundup. The 48-hour EC50 (the concentration that causes 50% of the population to die within 48 hours) for midge larvae was 55 mg/L, while that of Roundup was 2.3 mg/L.
Another study found that glyphosate did not affect rainbow trout up to concentrations of 10.0 mg/L, while Roundup affected the trout at concentrations of 1.0 mg/L. These studies suggest that glyphosate alone is less toxic to aquatic animals than formulated products like Roundup.
However, it is important to note that the toxicity of glyphosate and Roundup can vary depending on the species and environmental conditions. For example, one study found that Roundup was more toxic to rainbow trout and bluegills at higher test concentrations. Additionally, the presence of certain co-formulants in glyphosate-based herbicides (GBHs) can increase their toxicity. For instance, POEA, a co-formulant banned in the EU but still used in the USA, is toxic to the aquatic environment and amphibians due to its ability to disrupt membrane transport and act as a narcotic.
Overall, while glyphosate is considered less toxic than Roundup for aquatic animals, it still poses risks to aquatic life, especially when combined with other chemicals in formulated products. The limited data available also suggests that commercial formulations are more toxic than glyphosate alone for fungi. More research is needed to fully understand the side effects of glyphosate and its formulations on non-target soil and aquatic organisms.
