Can lobster still be eaten after it starts oozing black liquid?

It is not recommended to eat lobsters that exude black fluid. Fresh, healthy lobsters have firm, plump meat and clear bodily fluids; the presence of black discharge usually indicates spoilage or contamination, which may pose health risks if consumed. If you accidentally consume a lobster with black discharge and experience discomfort such as vomiting, diarrhea, or abdominal pain, seek medical attention promptly.

The primary cause of black fluid in lobsters is spoilage. After a live lobster dies, bacteria multiply rapidly inside its body, breaking down the flesh and internal organs and producing black, decomposed substances. This process is often accompanied by foul odor and slimy texture. Consuming such spoiled lobsters can lead to gastrointestinal infections due to harmful substances.

In addition, if the lobster's living environment is polluted, it may accumulate heavy metals or other toxic substances, which can also cause darkening of bodily fluids. These contaminants can build up in the body over time, and long-term or excessive consumption may damage vital organs such as the liver and kidneys.

When purchasing lobsters, choose live, active individuals with intact shells. Cook them promptly after purchase and avoid prolonged storage. Before cooking, thoroughly clean the underside and remove the digestive tract (vein). Ensure the lobster is fully cooked through. Do not consume lobsters of unknown origin, those with abnormal appearance, or those that are dead or spoiled.
