Identifying whether a snail is poisonous can be determined by looking at its shell color and shape. Most snails are non-toxic, but some secrete poisonous mucus, such as the violet snail and cone snail. Generally, the common snails in many regions are the white jade snails, which are often farmed for consumption. Touching snails generally does not lead to parasite infections, though it's still recommended to wash hands afterward to prevent any bacterial residue.
Snails are invertebrates that primarily feed on plants and are commonly found in tropical regions, though some also live in colder areas. There are numerous species of snails, rich in proteins and minerals, and often they are farmed as pets or for consumption. However, not all snails are harmless; some contain potent toxins that can be harmful to humans.
How to Identify Poisonous Snails
1. Shell Color:
Some snails with brightly colored shells might have poisonous secretions. Examples include the violet snail and the glitter snail, which can be dangerous if ingested.
2. Shell Shape:
Normal snails usually have low conical-shaped shells that are either dextral (right-handed) or sinistral (left-handed). If the shell shape appears unusual, it may indicate that the snail is toxic. Examples include the ornate cerith snail and cone snails.
Which Snails Are Non-Toxic and Edible?
The white jade snail is one of the most common snail species in many regions and is often artificially farmed. White jade snails have higher protein content than beef and lamb, while having low fat content. They are rich in vitamins and minerals, making them ideal for people with nutritional deficiencies. Consuming these snails can also be beneficial for skin and hair health.
