Are whelks poisonous?

Answered by Robert Flynn

Whelks can indeed be considered poisonous due to the presence of a toxic substance called tetramine in their salivary glands. This poison can cause various symptoms if the whelks are ingested without properly removing the salivary glands.

One of the most common symptoms experienced after consuming whelks with the salivary glands intact is a headache. This can range from a mild discomfort to a severe throbbing pain, depending on the individual and the amount of tetramine consumed. The headache typically develops within 30 minutes to an hour after ingestion.

Dizziness is another potential symptom of consuming whelks without removing the salivary glands. This sensation of lightheadedness can be accompanied by feelings of unsteadiness or a spinning sensation. It can be quite unsettling and may persist for a significant period of time, making it difficult to perform everyday tasks.

A feeling of seasickness is yet another possible symptom of ingesting whelks with the salivary glands still intact. This sensation is often described as a general feeling of discomfort and nausea, similar to what one might experience while on a boat in rough seas. This can be particularly distressing for individuals who are prone to motion sickness or have a sensitivity to such symptoms.

It is important to note that the severity of these symptoms can vary depending on the individual’s sensitivity to tetramine and the amount of poison consumed. Some individuals may experience only mild symptoms, while others may have a more pronounced reaction.

To avoid these symptoms, it is crucial to properly remove the salivary glands before consuming whelks. This can be done by carefully dissecting the whelk and removing the glands, ensuring that no trace of the poisonous substance remains.

Whelks can be considered poisonous due to the presence of tetramine in their salivary glands. Ingesting whelks without removing these glands can lead to symptoms such as headache, dizziness, and a feeling of seasickness. It is important to exercise caution and properly prepare whelks to avoid any potential harm.
