How Can You Tell if a Lobster is Dead or Alive?

Determining the state of a lobster, whether it’s dead or alive, is vital before consumption. One of the most apparent signs is the lobster’s claws. If the lobster claws are tightly clenched, the lobster is likely still alive, whereas relaxed claws suggest it might be dead.
Another indicator is the lobster tail. A live lobster typically curls its tail under its body, especially when lifted or handled. On the other hand, if the tail appears straight or limp, it’s a sign the lobster may have expired.
The lobster’s eyes offer another clue. A live lobster has bright and clear eyes, while a dead lobster has cloudy or sunken eyes. Lastly, the smell is an obvious determinant. A strong, offensive odor is a sure sign of a dead lobster.
Is It Safe to Cook and Eat a Dead Lobster?
Yes, it’s safe to cook and eat dead lobster with precautions. It’s important to cook and consume the lobster within two hours of its death to reduce the risk of food poisoning. Lobsters that are refrigerated can be safe for up to 24 hours, but this isn’t the ideal method.
What To Do If Your Lobster Is Dead
If your lobster is dead upon arrival, check its quality. If it’s in good condition, is cool to the touch, and doesn’t have a foul smell, it can be safely cooked and consumed. Our local lobster fishermen catch live Maine lobsters daily for next day shipping to you, ensuring safe consumption.
Check For Signs Of Rot And Decay

Before proceeding to cook a lobster, especially one that has been dead before cooking, it’s essential to inspect it for indications of rot and decay. These signs serve as a warning that the lobster might not be safe to consume.
A pungent, unpleasant smell is a clear red flag. Additionally, look for visual cues: cloudy or sunken eyes and a soft or discolored shell can mean that the lobster is decaying. Similarly, the flesh’s texture can offer insights; if it’s slimy, mushy, or resembles cottage cheese, this suggests that the meat has rotted.
Always prioritize your health and safety; when in doubt, it’s best to discard the lobster rather than risk potential foodborne illnesses.
How to Safely Cook a Dead Lobster
- Use a meat thermometer: Ensure the internal temperature reaches at least 145°F (63°C)
- Prevent cross-contamination: Use separate cutting boards and utensils
- Discard leftovers within two hours of cooking
Do You Have to Eat Lobster Right Away?
While it’s ideal to eat lobsters as soon as they’re cooked, dead lobsters should be consumed within two hours if they’ve been left at room temperature. Refrigeration can extend this time up to 24 hours.
What Happens If You Eat a Dead Lobster?

Consuming a lobster that has been dead for an extended period can pose serious health risks. When a lobster dies, a natural process called autolysis begins, where the muscles start to break down and decompose.
This decomposition can lead to the rapid growth of bacteria, and these bacteria can produce toxins harmful to humans. Even if you were to cook the lobster, certain toxins produced by the bacteria might remain, potentially leading to food poisoning.
Food poisoning symptoms can range from mild digestive discomfort to more severe symptoms like nausea, vomiting, diarrhea, and abdominal pain. Additionally, the overall quality of the lobster’s meat deteriorates when it’s dead for too long, resulting in an unpleasant taste and texture.
The meat can turn mushy, stringy, and discolored. That’s why it’s important to make sure the lobster is fresh, whether alive or recently deceased, before cooking and consumption to avoid any adverse health consequences.
Frequently Asked Questions

Lobsters, with their intricate biology and unique culinary attributes, lead to many questions among consumers and cooking enthusiasts. Here, we’ve answered some of the most common questions to cater to your lobster curiosities:
Do Lobsters Move After They Die?
Once a lobster passes away, its bodily functions stop, leading to a state of inertia. This means they no longer show any signs of movement and their bodies turn limp and inactive, quite different from their usual lively nature.
How Long Can You Keep Dead Lobster in the Fridge?
Preserving the freshness of lobster meat is crucial. While we generally don’t advise it, if you find yourself with a dead lobster, it can be safely stored in a refrigerator for up to 24 hours if it’s kept at temperatures below 40°F. After this period, the quality and safety of the meat may be compromised.
How Long Can a Lobster Survive Out of Water?
Lobsters are remarkably resilient creatures. Even outside their natural aquatic habitat, they can survive for several days as long as they are kept in cool and moist conditions. However, for optimal health and quality, it’s best to minimize their time out of water.
What’s the Green Stuff in Lobster?
When dissecting a lobster, you might come across a green substance. This is called tomalley and is essentially the liver of the lobster. Contrary to initial reactions, many lobster connoisseurs regard tomalley as a delicacy thanks to its distinct flavor profile.
Black Stuff Inside Lobster?
Finding black stuff inside a lobster can be concerning. However, this typically signifies that you have an under-cooked female lobster. This black substance can easily be rinsed away. We recommend cooking the lobster until it’s completely done to ensure both safety and taste.
