What Happens if You Eat Bad Lobster? The Potential Risks and How to Avoid Them

We’ve all found ourselves in a situation where we have too much leftover food. You might have made too much for a big dinner, or you might have been a guest and got some leftovers from the host. No matter the reason, you may be wondering if that lobster that you have left over is still safe to eat.

Lobster is one of those luxurious seafood treats that we love to indulge in once in a while. When fresh it has that sweet, succulent meat with the most wonderful briny flavor. But lobsters are also highly perishable and a bad lobster can spell disaster if consumed. So what exactly happens if you eat bad lobster? Let’s take a closer look.

Eating spoiled or contaminated lobster can potentially lead to foodborne illness, symptoms of which can range from mild to severe. According to the Centers for Disease Control and Prevention (CDC), around 48 million people get sick from foodborne diseases every year in the United States, resulting in over 128,000 hospitalizations and 3,000 deaths.

Seafood including lobster is one of the most common culprits. Bacteria like Salmonella, Vibrio parahaemolyticus, Clostridium perfringens, Staphylococcus aureus, Listeria monocytogenes, and Campylobacter are often the source of seafood-related food poisoning. Eating bad lobster provides the perfect breeding ground for these nasty bugs to multiply and wreak havoc.

What Kinds of Illness Can You Get From Eating Bad Lobster?

Here are some of the common foodborne illnesses that may occur:

Salmonellosis

This is one of the most frequently reported foodborne diseases. Salmonella infection causes diarrhea, fever, chills, stomach cramps, nausea, and vomiting. Symptoms usually start 12 to 72 hours after ingesting contaminated food and last for 4 to 7 days.

Vibriosis

Caused by Vibrio bacteria, this leads to watery diarrhea, abdominal cramping, nausea, vomiting, fever, and chills. It’s contracted by eating raw or undercooked seafood, like oysters and lobster. Symptoms occur within 24 hours.

Listeriosis

This infection has a long incubation period of 3 weeks. Symptoms are fever, muscle aches, nausea, and diarrhea. It primarily affects pregnant women, newborns, older adults, and those with weakened immune systems.

Staphylococcal Food Poisoning

Caused by the Staphylococcus aureus bacteria, it results in diarrhea and vomiting. Abdominal cramping and fever may also occur. Onset time is 1 to 6 hours after ingesting contaminated food.

Campylobacteriosis

This bacterial infection triggers diarrhea, cramping, abdominal pain, nausea, and vomiting. Symptoms start 2 to 5 days after exposure.

Ciguatera Poisoning

This is caused by toxins produced from dinoflagellates, absorbed by fish and shellfish. Diarrhea, vomiting, numbness, tingling, muscle pain, weakness, dizziness, and itching around the mouth may occur.

As you can see, the common symptoms are abdominal discomfort, diarrhea, vomiting, nausea, fever, and fatigue. In most cases, it resolves on its own in a few days. But certain groups like pregnant women, children, older adults and those with compromised immunity are at higher risk of developing complications like reactive arthritis, Guillain-Barre syndrome, and hemolytic uremic syndrome.

Sometimes, toxins like Ciguatoxin can cause neurological symptoms like tingling, numbness, and paralysis. And Vibrio vulnificus can even lead to septicemia, tissue destruction, and death in individuals with liver disease or weakened immune systems.

So while eating spoiled lobster doesn’t often end fatally, it’s certainly an unpleasant experience. And you want to take adequate precautions to avoid it.

How Does Lobster Get Contaminated in the First Place?

Now you may wonder, how does lobster get contaminated with these nasty bugs if it comes straight out of the pristine ocean waters? Well, here are some ways it can happen:

During storage – Lobsters are often stored for long periods before being transported to retailers. Unsanitary storage conditions can lead to rapid multiplication of bacteria.
During processing – Handling by workers, use of dirty processing equipment and utensils increases the risk of cross-contamination.
Improper cooking – Not heating lobster to the right internal temperature results in bacteria surviving the cooking process. The recommended safe internal temperature is 145°F.
Reusing leftovers – Leftover lobster stored at incorrect temperatures or reheated improperly can also harbor bacteria.
Contaminated tank water – At supermarkets and seafood retailers, lobsters stored in tanks with unclean water can get contaminated.

So contamination can occur at multiple points before that lobster finally reaches your plate. Proper handling and cooking are crucial to prevent foodborne illnesses.

What Should You Do if You Suspect You’ve Eaten Bad Lobster?

If you ate some lobster and now suspect it may have been spoiled, here’s what you need to do:

Watch out for symptoms – Be vigilant about any stomach discomfort, nausea, diarrhea or other symptoms in the hours following your meal. Foodborne illnesses have quick onset times ranging from 1 to 72 hours after ingesting contaminated food.
Stay hydrated – Drink plenty of fluids, like water, clear soups, and oral rehydration solutions. Vomiting and diarrhea can quickly dehydrate you. Preventing dehydration is key.
Call your doctor – If symptoms are severe or persist beyond a day or two, call your doctor immediately. You may need medical attention and antibiotics.
Report the incident – Inform the grocery store, restaurant or retailer where you purchased the lobster. This helps prevent future illnesses.

The key is to act quickly if you suspect you’re suffering from a foodborne illness. Early treatment can reduce the severity and duration of symptoms.

How to Tell if Your Lobster Has Gone Bad

Clearly, you want to avoid getting into a situation where you’ve consumed spoiled lobster in the first place. But how do you tell if that lobster sitting in your fridge or the one you just brought home is bad? Here are some easy ways to identify a spoiled lobster:

Give it a sniff – Fresh lobster has a mild briny aroma while spoiled lobster smells quite off, often like ammonia. An unpleasant fishy or sour odor is a huge red flag.
Check the texture – Fresh lobster meat feels firm. Bad lobster has a mushy texture resembling cottage cheese. Sliminess is also a sign of spoilage.
Observe the color – The meat should look creamy white or pinkish-white. Gray, brown or greenish meat indicates spoilage.
See if it’s active – Live lobsters are typically active when handled. A weak or lifeless lobster is past its prime.
Watch for damage – Cracked shells or tails and puncture wounds make raw lobster prone to bacteria. Discard any damaged lobster.
Verify shelf life – Cooked lobster meat lasts only 3-4 days refrigerated. Frozen, it’s safe for 4 months. Discard leftovers beyond this.

Following basic food safety practices is vital too. Don’t leave lobster unrefrigerated for over 2 hours. Store cooked lobster drained of water at 40°F or below. Handle raw and cooked lobster separately to prevent cross-contamination.

Taking these simple precautions ensures you can enjoy your lobster while also avoiding any tummy troubles or other illness.

How to Safely Handle, Store and Cook Lobster

Mishandling and improper storage are two of the main reasons lobster gets contaminated. Here are some tips on safely handling lobster:

Purchase live lobsters close to when you plan on cooking them. The fresher, the better.
Ensure live lobsters are alert and active in tanks. Avoid lethargic lobsters.
Separate live lobsters from other foods during transport. Prevent cross-contamination.
Store live lobsters in the refrigerator below 40°F. Place atop ice or in a breathable container.
Cook live lobsters within 24 hours of purchasing. Discard any dead lobsters.
Sanitize surfaces, tools and hands after handling raw lobster. Prevent spread of bacteria.
Discard lobster with unpleasant odors, damaged shells or mushy texture. Do not consume bad lobster.
Cook lobster to an internal temperature of at least 145°F. This kills potentially harmful bacteria.
Rapidly chill cooked lobster meat and store in shallow airtight containers below 40°F.
Reheat cooked lobster to 165°F. Reheating at lower temperatures can encourage bacterial growth.
Avoid intermittently cooling and reheating lobster multiple times. This increases spoilage.

Following safe procurement, handling, cooking, cooling, storage, and reheating guidelines reduces the risks of foodborne illness. Take the necessary precautions.

How Long Does Lobster Meat Last?

The answer to this question depends on whether or not your lobster meat is cooked. Uncooked lobster meat lasts only a few hours—this is why most lobsters are boiled alive at restaurants.
