May 21, 2008 – Not all lobster lovers enjoy lobster tomalli, but those who eat it should limit their consumption, recommends Health Canada.
Tomalli, this green substance found in the lobster cavity, takes over the functions of the liver and pancreas. As it acts as a natural filter for contaminants, it may contain a marine toxin called paralyzing phycotoxin.
To avoid intoxication, the daily consumption of tomalley for an adult should be limited to the amount contained in two lobsters and in one lobster for a child, specifies Health Canada.
This restriction does not apply to canned tomalli, which is subject to strict control. The toxin is also not detectable in lobster meat.
When consumed in large quantities, paralyzing phycotoxin can affect the human nervous system. The first signs of poisoning are a feeling of tingling or numbness of the lips that gradually invades the face and neck.
Other symptoms may appear in the case of a more serious intoxication: a feeling of tingling in the extremities, headache, dizziness and nausea. In rare cases, there is paralysis of the respiratory muscles which can be fatal.
In the presence of one or more of these symptoms, Health Canada recommends consulting a health care professional without delay.
