Generally speaking, the green tomalley found in the head of a Boston lobster is edible and highly nutritious. However, it is essential to ensure the lobster is fresh, properly handled, and consumed in moderation. The details are as follows:
The green tomalley is the lobster's hepatopancreas, rich in protein, minerals, and unsaturated fatty acids, with a rich and savory flavor. When consumed in appropriate amounts, it provides valuable nutrients and is considered the most flavorful part of the lobster. In fresh lobsters, the tomalley has no unpleasant odor and a uniform texture. Once thoroughly cooked, it is safe to eat and unlikely to cause discomfort.
If the lobster is not fresh, spoiled, or comes from a polluted environment, the tomalley may accumulate harmful substances such as bacteria and heavy metals. Consuming it under these conditions could irritate the gastrointestinal tract, leading to symptoms like abdominal pain and diarrhea. Additionally, tomalley is high in cholesterol; excessive consumption may increase metabolic strain on the body, particularly for individuals with elevated blood lipid levels.
Before eating, the lobster should be thoroughly cleaned to remove impurities from the head, and must be fully cooked. During regular consumption, portion control is important. Pairing it with vegetables, whole grains, and other balanced ingredients, along with selecting live, high-quality lobsters from reliable sources, allows one to enjoy its flavor while ensuring food safety.
