The first time you open a cooked lobster and see a bright green substance inside, it can be surprising. Many people wonder whether it is safe to eat or should be avoided. The green material is called **tomalley**, and it is the lobster’s digestive gland. It works like a combination of a liver and pancreas, helping the lobster digest food, store nutrients, and filter substances from its body.

For many seafood lovers, tomalley is considered a delicacy. Its rich, creamy texture and strong briny flavor make it popular for spreading on toast, mixing into seafood sauces, or adding to lobster dishes. While some chefs enjoy its distinctive taste, others leave it out because they know its flavor is not for everyone.

Tomalley can also collect certain contaminants because it filters what the lobster eats. It may contain higher levels of environmental pollutants, naturally occurring toxins, or harmful compounds produced during algae blooms. For that reason, several food safety agencies recommend limiting or avoiding it, especially when shellfish advisories are in effect. Although many people eat tomalley without issue, experts generally advise being cautious rather than making it a regular part of your meal.

If you decide to eat tomalley, it is best to buy lobster from reputable sources and waters that are regularly monitored for safety. Even then, moderation is recommended. Many diners simply remove the green substance and enjoy the sweet, tender lobster meat instead, while others continue to enjoy tomalley as part of the experience.

In the end, there is no single right answer. Some people believe tomalley is one of the tastiest parts of the lobster, while others prefer to skip it. Knowing what it is, how it works, and why experts sometimes recommend caution can help you make the choice that feels right for you. As the article notes, **”the true enjoyment of seafood comes not just from its flavor, but from knowing exactly what’s on your plate and deciding what’s right for you.”**
