Garden snails are commonly found in Australia, but most of these are not native to the country. While some people eat garden snails, nutritionists advise against consuming snails directly from the garden due to the potential presence of toxins. Native Australian snails are not vegetarian and do not eat garden plants. Instead, they feed on fungi, micro-algae on plant leaves, and biofilm on most surfaces.

What You'll Learn
Australian garden snails are not vegetarians
Firstly, it is important to note that most of the snails found in Australian gardens are not native species. The common garden snail, for example, was introduced to Australia from Europe and is typically found near human populations in cities.
Native or not, Australian garden snails have a diverse appetite. They feed on fungi, micro-algae found on leaf surfaces, and biofilm, which is present on most surfaces. This diet means they are not dependent on garden plants for sustenance, contrary to what many people may think.
In fact, some Australian snails are even carnivorous. Certain species, like the Glossy Turban Carnivorous Snail, will follow the slime trails of other snails to make a meal out of them. This behaviour demonstrates that snails can be just as happy consuming animal matter as they are plant matter.
Additionally, it is worth noting that some people do choose to eat garden snails themselves. While nutritionists advise against consuming snails directly from the garden due to potential pesticide exposure, some individuals still forage for them and prepare them in a variety of ways, including boiling and cooking them with spices, butter, garlic, and chilli.

They eat fungi
While Australian garden snails are not vegetarians, they do eat fungi. This means that they will not eat your garden plants. In addition to fungi, they also eat micro-algae on the leaves of plants and biofilm on most surfaces.
The largest land snail in Australia is the Giant Panda Snail (Hedleyella falconeri), which can be found in the rainforest, happily searching for food. This snail, like other Australian native snails, is not a vegetarian.
The Giant Panda Snail is not the only snail that enjoys a good meal of fungi. The Sphaerospira fraseri, for example, has been spotted dining on fungi at Mt Glorious. This just goes to show that Australian snails have a varied diet that includes more than just plants.
It is important to note that while these snails may not eat your garden plants, they can still cause some damage. They do this by leaving behind slime trails, which can be unsightly and may even attract pests. However, overall, Australian garden snails are not a major threat to your garden and can even help control the population of certain pests.

They eat micro-algae on leaves
Interestingly, Australian garden snails are not vegetarians. They do not eat garden plants. Instead, they feed on micro-algae found on the leaves of plants. This diet is not unique to Australian snails, as most snails and slugs found in Australian gardens are non-natives. In fact, there are over 1000 species of native Australian snails and slugs, and the majority of garden snails are introduced species, originally from Europe.
The micro-algae that Australian garden snails consume are tiny, single-celled organisms that can be found on the surface of leaves. These algae are too small to be seen by the naked eye, but they provide a nutritious meal for snails. The snails scrape off the micro-algae with their radula, a tongue-like structure covered in tiny teeth, and then use their sharp teeth to grind the algae into a digestible paste.
The diet of Australian garden snails is not limited to micro-algae. They are also known to eat fungi and biofilm, which is a thin layer of bacteria and other microorganisms that can be found on most surfaces. This diverse diet allows them to survive in a variety of habitats, including urban environments.
It is important to note that while some people may consider consuming garden snails as a delicacy, it is not recommended to collect and eat snails from your garden. Garden snails can carry diseases and consume pesticides and poisons, which can be harmful to humans. If you are interested in eating snails, it is safer to purchase them from a reputable source or forage for them in the wild under expert guidance.

They eat biofilm on most surfaces
While Australian garden snails are not vegetarians, they do not eat garden plants. They are known to eat biofilm on most surfaces, as well as fungi and micro-algae on the leaves of plants. This means that they will not harm your garden plants. In fact, there are over 1000 species of native Australian snails and slugs, and most of the snails found in backyards are non-natives.
Biofilms are thin, slimy layers of bacteria that form on various surfaces, including leaves, rocks, and even other animals. They are a source of food for many organisms, including Australian garden snails. The snails use their radula, a tongue-like structure with small teeth, to scrape off and consume the biofilm.
Biofilms can also serve as a protective layer for the underlying surface, shielding it from environmental damage and helping to retain moisture. Additionally, they can provide a habitat for other microorganisms, contributing to the overall biodiversity of the ecosystem.
However, biofilms can become problematic when they form on artificial surfaces, such as pipes or medical equipment, as they can lead to corrosion or the spread of infections. In these cases, biofilms are often removed or treated to prevent potential harm.
Despite their important role in the ecosystem, Australian garden snails can be a concern for homeowners due to their potential to carry and transmit pesticides and poisons commonly found in gardens. Therefore, it is generally not recommended to consume garden snails unless proper precautions are taken to purge them of any harmful toxins.

Garden snails can be purged of toxins
Australian garden snails are not vegetarians, contrary to popular belief. They do not eat garden plants, but instead, feed on fungi, micro-algae on plant leaves, and biofilm on most surfaces. While some people consider these snails a delicacy, consuming them straight from the garden is not advisable due to the potential presence of toxins.
Step 1: Diet Adjustment
The first step is to change the snail's diet. For a period of about five days, the snails are fed a controlled diet of lettuce, carrots, or other vegetables. This helps to replace any harmful substances in their system with healthier, more nutritious food.
Step 2: Starvation Period
After the diet adjustment, the snails are then deprived of food for a couple of days. This step is crucial as it gives the snails' bodies time to eliminate any remaining toxins. During this time, the snails may be kept in a container with a damp cloth or paper towel and a few holes for ventilation.
Step 3: Cooking and Preparation
After the purging process, the snails can be cooked in a variety of ways, often involving spices, butter, garlic, and chilli. It is worth noting that the taste of the snail meat is heavily influenced by the flavours it is cooked with.
It is important to note that even after purging, there may still be traces of toxins in the snail's meat, so it is consumed at one's own risk. This process is not a guaranteed method to remove all toxins, and consuming wild snails always carries some level of risk.
While garden snails may be a source of protein, it is always advisable to exercise caution and consult experts or official guidelines before consuming them.
