Why Do Snails Carry Disease

Snails carry disease because they are able to transmit parasites and bacteria that cause a variety of illnesses in humans. Snails can become infected with parasites, such as schistosomes and liver flukes, which may be passed on through water or food contaminated by snail waste. Additionally, snails serve as intermediate hosts for certain diseases, allowing them to spread from one species to another.

For example, some types of trematode worms require snails for development before infecting other animals. Bacteria including Salmonella and E. coli have also been found in snail slime or feces and can contaminate nearby soil or water sources causing infections when ingested by people or animals.

Snails carry disease because they are intermediate hosts for a number of parasites, including some that can cause serious illnesses in humans. The most common snail-borne diseases include schistosomiasis, which is caused by parasitic worms; leptospirosis, which is transmitted through contact with the urine of infected animals; and angiostrongyliasis, which is caused by roundworms. In addition to these conditions, snails can also transmit other bacterial and viral infections such as salmonellosis and echinococcosis.

Why Do Snails Carry Disease


How Do Snails Cause Disease?

Snails are often seen as harmless, friendly creatures but they can actually be carriers of a variety of diseases. Snails and slugs carry parasites that can cause disease in humans and animals alike. The most common snail-borne disease is schistosomiasis, which is caused by the parasite Schistosoma mansoni.

This parasite lives inside the body of snails, where it multiplies before being released into water sources such as lakes or rivers. If a person comes into contact with contaminated water, they can become infected via skin contact or ingestion. Symptoms include fever, chills, headaches and abdominal pain; if left untreated it can lead to liver damage or bladder cancer.

Other illnesses associated with snails include angiostrongyliasis (a type of meningitis) and fasciolopsiasis (intestinal infection). In addition to these direct infections from snail-borne parasites, snails have also been linked to the spread of diseases such as malaria and dengue fever through their role in transmitting mosquito larvae between bodies of water.

Can Snails Pass Disease to Humans?

Yes, snails can pass diseases to humans in a few different ways. For example, the parasite that causes schistosomiasis (also known as snail fever) is commonly contracted through contact with contaminated water sources such as rivers and lakes that are home to infected freshwater snails. The parasite leaves these snails and enters human skin when exposed to the water for an extended period of time.

Additionally, some species of land-dwelling snails have been linked to outbreaks of meningitis caused by rat lungworm larvae, which can be passed on via raw or undercooked mollusks like escargot dishes. Lastly, certain types of marine gastropods such as cowries may also spread disease if their shells become infested with certain types of bacteria or viruses that can then be passed onto humans who handle them without protection and proper sanitization practices. Therefore, it is important for people to take caution when handling any type of snail and practice appropriate hygiene measures afterwards in order to avoid potential illnesses.

Can You Get Sick from Handling Snails?

Yes, you can get sick from handling snails. Snails and slugs may seem harmless, but they can carry a parasitic worm called rat lungworm (Angiostrongylus cantonensis) which causes eosinophilic meningitis in humans. The disease is spread when humans ingest food contaminated with the tiny larvae of the parasite.

Handling snails or coming into contact with their mucus is one way to become infected. In addition to causing meningitis, this infection has been linked to pain and swelling in joints as well as muscle weakness and numbness throughout the body. Symptoms usually appear within 2-8 weeks after initial exposure but some cases have been reported where symptoms appeared up to 6 months later.

If you handle snails it’s important that you wash your hands thoroughly afterwards in order to reduce your risk of becoming infected with this parasite.

Is It Safe to Touch a Snail?

It is generally safe to touch a snail, but there are some precautions you should take. Snails carry bacteria that can cause infections in humans if their slime or mucus comes into contact with open cuts or wounds on your skin. If you have any open sores, it is best not to touch the snail at all.

Additionally, snails may contain parasites that can make people sick if they come into contact with them. The most common of these illnesses would be salmonella poisoning from handling garden snails, so it’s important to wash hands thoroughly after touching them as well as any surfaces they touched before and after being handled. Lastly, even though snails don’t usually bite humans because of their small mouths, it is possible for them to do so in certain circumstances; thus extra caution should be taken when handling the animal.

Why Snails Kill 200 000 People Every Year

Snail Diseases And Treatment

Snails are surprisingly vulnerable to a variety of diseases, including parasites, bacterial infections and fungal infections. Common treatments for snail illnesses involve antibiotics or other anti-parasitic medications that can help fight off the infection. It is also important to keep your tank clean and maintain optimal water parameters for your snails in order to prevent disease.

If you suspect your snail may be ill, it’s best to seek out advice from a qualified veterinarian who is experienced in treating snail ailments.


Schistosomiasis is a parasitic disease caused by infection with flatworms from the genus Schistosoma. It affects more than 240 million people, mostly in tropical and subtropical countries, causing anemia, malnutrition and other health problems. Treatment involves preventing contact with contaminated water sources as well as medications to kill the parasite.

Vaccines are currently being developed but are not yet available for widespread use.

Garden Snail Parasites

Garden snails are vulnerable to a variety of parasites, including various protozoans and fungi. These parasites can cause serious damage to the snail’s soft body tissue, leading to death if left untreated. Common symptoms include discolored patches on the shell or mucus-like secretions around its mouth and eyes, as well as lethargy or difficulty moving.

If you suspect your garden snail has been infected with a parasite, contact an experienced veterinarian for treatment options.

Disease from Snails And Slugs

Snails and slugs can be carriers of human diseases, such as rat lungworm. Rat lungworm is a parasitic roundworm that can cause eosinophilic meningitis in humans when ingested with contaminated food or water. Symptoms of this disease include headache, stiff neck, nausea, vomiting and altered mental status.

While it is rare for humans to get sick from snails and slugs carrying the parasite, it’s still important to take precautions by avoiding contact with them and washing your hands after handling any potential contaminated material.

Snail Disease in Humans

Although it is rare, humans can contract diseases from snails. Schistosomiasis, also known as snail fever, is a parasitic disease caused by several species of trematode worms and is spread by infected freshwater snails. Symptoms may include fever, chills, coughs, muscle aches and fatigue.

If left untreated the symptoms can worsen and even lead to organ damage or death in extreme cases. It’s important to seek medical attention if you think you may have contracted any type of illness from a snail so that it can be properly diagnosed and treated.

Snail Parasite Human

A parasitic snail, called a schistosome, can cause an infection in humans known as ‘schistosomiasis’. This is one of the most common parasitic infections worldwide and affects over 200 million people. Symptoms include fever, rash, fatigue and abdominal pain.

If left untreated it can lead to more serious medical issues such as liver damage or kidney failure. To protect yourself from this dangerous parasite it is important to practice good hygiene when swimming in fresh water lakes or rivers that may be infected with these snails.

Aquarium Snail Parasites

Aquarium snails are prone to parasites, like many other animals. The most common types of snail parasites include digeneans, trematodes, and nematodes. These parasites can cause serious health problems for the snail if left untreated; symptoms may include lethargy, loss of appetite, or even death in severe cases.

To keep your aquarium snails healthy and parasite-free it is important to provide them with a clean environment with plenty of oxygenated water as well as regularly check for signs of infection.

Can You Get Rat Lungworm from Touching a Snail

No, you cannot get rat lungworm from touching a snail. Rat lungworm is caused by the parasite Angiostrongylus cantonensis, which can be contracted through eating raw or undercooked snails and slugs that are infected with the parasite. Therefore, it is important to thoroughly cook any snails or slugs before consuming them in order to avoid contracting this potentially serious health condition.


Overall, this blog post has highlighted the ways in which snails can spread diseases and how they can affect humans. We have learned that snail-borne illnesses commonly occur in tropical or subtropical climates, but that doesn’t mean people should be complacent about them everywhere else. People should take precautionary measures to protect themselves from contracting any diseases carried by snails regardless of where they live.

As a result, it is important for us to be aware of the risks associated with coming into contact with snails and their habitats so we can all stay safe and healthy.
