Snails, those sluggish, shell-bearing creatures, have been a part of our ecosystem for millions of years. While they may seem harmless, even beneficial, to the environment, the question remains: are snails harmful to humans? In this article, we’ll delve into the world of snails and explore the potential risks and consequences of interacting with these slimy creatures.
Snail-Borne Diseases: A Growing Concern
Snails are known to carry a variety of diseases and parasites that can be transmitted to humans. One of the most significant concerns is the risk of contracting rat lungworm disease, also known as angiostrongyliasis. This parasitic infection is caused by the Angiostrongylus cantonensis worm, which is commonly found in snails and slugs.
The disease is typically spread through the consumption of contaminated snails or slugs, often in the form of undercooked or raw snail meat. In some cases, the parasite can also be transmitted through contact with contaminated feces or vomit. Symptoms of rat lungworm disease can range from mild to severe and include:
- Severe headaches
- Stiff neck
- Fever
- Vomiting
- Abdominal pain
In severe cases, the disease can cause meningitis, encephalitis, or even death.
Other Snail-Borne Diseases
In addition to rat lungworm disease, snails can also carry other diseases and parasites, including:
- Schistosomiasis: a parasitic infection caused by the Schistosoma parasite, which can cause symptoms such as abdominal pain, diarrhea, and fatigue.
- Fascioliasis: a parasitic infection caused by the Fasciola parasite, which can cause symptoms such as abdominal pain, diarrhea, and weight loss.
- Leptospirosis: a bacterial infection caused by the Leptospira bacteria, which can cause symptoms such as fever, headache, and muscle aches.
Snail Allergies and Intolerances
Some people may be allergic or intolerant to snails, which can cause a range of symptoms, from mild to severe. Snail allergy is a rare condition that can cause symptoms such as:
- Hives
- Itching
- Swelling

- Diarrhea
In severe cases, a snail allergy can cause anaphylaxis, a life-threatening allergic reaction.
Snail Intolerance
Snail intolerance is a non-allergic condition that can cause symptoms such as:
- Bloating
- Gas
- Abdominal pain
- Diarrhea
Snail intolerance is often caused by the inability to digest certain proteins or compounds found in snails.
Snail Bites and Stings
While snails do not typically bite or sting, some species of snails can cause skin irritation or allergic reactions. The cone snail, for example, is known to produce a venom that can cause severe pain, swelling, and respiratory distress.
Snail Venom
Snail venom is a complex mixture of compounds that can cause a range of symptoms, from mild to severe. In some cases, snail venom can cause:
- Severe pain
- Swelling
- Redness
- Itching
- Respiratory distress
Prevention and Treatment
While snails can pose a risk to human health, there are steps that can be taken to prevent and treat snail-borne diseases and allergies.
Prevention
To prevent snail-borne diseases and allergies, it’s essential to:
- Avoid eating undercooked or raw snail meat
- Wash hands thoroughly after handling snails or slugs
- Avoid touching eyes or mouth after handling snails or slugs
- Wear protective clothing and gloves when handling snails or slugs
Treatment
Treatment for snail-borne diseases and allergies typically involves:
- Antiparasitic medication
- Antibiotics
- Antihistamines
- Corticosteroids
In severe cases, hospitalization may be necessary to treat complications such as meningitis or anaphylaxis.
Conclusion
While snails may seem harmless, they can pose a significant risk to human health. By understanding the potential risks and consequences of interacting with snails, we can take steps to prevent and treat snail-borne diseases and allergies. Whether you’re a snail enthusiast or simply a concerned citizen, it’s essential to be aware of the slimy truth: snails can be harmful to humans.

Are snails poisonous to humans?
Snails are not typically poisonous to humans. However, some species of snails can carry a parasite called rat lungworm, which can cause a type of meningitis in humans if ingested. This parasite is usually found in snails that have been infected by eating contaminated feces or other infected animals.
It’s essential to note that the risk of getting infected by rat lungworm from snails is relatively low, especially if you handle snails properly and cook them thoroughly before consumption. In some cultures, snails are considered a delicacy and are eaten regularly without any issues. Nevertheless, it’s crucial to be aware of the potential risks and take necessary precautions when handling snails.
Can snail slime harm humans?
Snail slime, also known as snail mucin, is generally not harmful to humans. In fact, it has been used in some skincare products due to its potential benefits for the skin, such as moisturizing and anti-aging properties. Snail slime contains glycoproteins, glycolic acid, and hyaluronic acid, which can help to soothe and protect the skin.
However, some people may experience an allergic reaction or skin irritation when using products containing snail slime. This is usually due to the presence of other ingredients in the product rather than the snail slime itself. If you’re considering using snail slime products, it’s recommended to do a patch test first to ensure you don’t have any sensitivity or allergic reactions.
Do snails carry diseases that can be transmitted to humans?
Snails can carry various diseases and parasites that can be transmitted to humans, including rat lungworm, as mentioned earlier. They can also carry other parasites like tapeworms and hookworms, which can cause intestinal infections in humans. Additionally, snails can carry bacteria like Salmonella and E. coli, which can cause food poisoning.
It’s essential to handle snails safely and cook them thoroughly before consumption to minimize the risk of disease transmission. Washing your hands thoroughly after handling snails or their slime is also crucial to prevent the spread of diseases. If you’re planning to eat snails, make sure to source them from a reputable supplier and follow proper food safety guidelines.
Can snail bites harm humans?
Snail bites are generally not harmful to humans. Snails do not have teeth, and their mouth is designed for eating plants and other soft materials. While snails can bite, their bite is usually not strong enough to cause significant harm to humans.
However, some people may experience minor irritation or redness at the site of the bite. This is usually due to the snail’s saliva, which can cause an allergic reaction in some individuals. If you experience any symptoms after being bitten by a snail, it’s best to wash the area with soap and water and apply a topical cream to soothe the skin.
Are snails a nuisance in gardens and homes?
Snails can be a nuisance in gardens and homes, especially if they’re present in large numbers. They can cause significant damage to plants, flowers, and crops by eating holes in leaves and stems. Snails can also leave behind a trail of slime, which can be unsightly and difficult to clean.
To control snail populations in your garden or home, you can use various methods, such as copper tape, crushed eggshells, or beer traps. You can also use snail baits or repellents, but be sure to follow the manufacturer’s instructions and take necessary precautions to avoid harming pets or other animals.
Can snails be used for medicinal purposes?
Snails have been used in traditional medicine for centuries, particularly in Europe and Asia. Snail slime, in particular, has been used to treat various skin conditions, such as acne, eczema, and psoriasis. It’s also been used to promote wound healing and reduce inflammation.
Some modern studies have confirmed the potential medicinal benefits of snail slime, including its antibacterial and anti-inflammatory properties. However, more research is needed to fully understand the effects of snail slime on human health. If you’re considering using snail slime for medicinal purposes, it’s best to consult with a healthcare professional first.
How can I safely handle snails?
To safely handle snails, make sure to wash your hands thoroughly before and after handling them. Wear gloves if possible, and avoid touching your face or eyes while handling snails. If you need to pick up a snail, gently grasp the shell and avoid touching the snail’s body or slime.
When handling snails, it’s also essential to avoid squeezing or crushing them, as this can cause them to release their slime and potentially infect you with parasites. If you’re planning to eat snails, make sure to cook them thoroughly before consumption to minimize the risk of disease transmission.
