How do you tell if mussels are bad after cooking?

One of the most important things to know about cooking mussels is how to tell if they are bad after cooking.

Mussels can spoil quickly, so it’s important that you know how to tell if they are safe to eat.

In this blog post, we will discuss the signs that mussels are bad after cooking, and we will give you some tips on how to prevent them from spoiling in the first place!

What does a dead mussel look like? If the shell has been broken or cracked in any way the mussel is dead and is not safe to consume.

Check the opening on the shell. If it’s fully open, the mussel has a problem. Verify that the opening of the shell is only partially open.

If the mussel is dead, you’ll see that the meat has turned red or brown. If it’s still alive, the meat will be off-white in color.

Another way to tell if a mussel is dead is by giving it a tap on the shell. If there’s no response, it means that the mussel has died and is not safe for consumption.

If you have any doubt about whether a mussel is alive or dead, it’s best to err on the side of caution and throw it away.

It’s not worth taking the risk of becoming ill from eating a bad mussel. When shopping for mussels, look for those that have shells that are tightly closed.

Avoid buying mussels with cracked or broken shells. If you find a mussel with an open shell, give it a tap. If there’s no response, put it back and look for another one.

How long can mussels stay in the fridge?

Cover the mussels in a moist cloth or paper towel. It’s essential not to keep the mussels in the water.

Put them in the refrigerator and keep for 2 to 5 days. Keep an eye on the Mussels regularly and flush any water that has accumulated.

Drain and replace the water every day. When you are ready to cook the mussels, remove them from the refrigerator and rinse thoroughly under cold water.

Some people like to soak their mussels for a few minutes in fresh water before cooking but I don’t find this necessary.

If your mussels are particularly sandy, you can give them a quick scrub with a brush under cold running water. Discard any mussels that are open or have cracked shells.

What do bad mussels smell like?

Clean and then store the mussels first time you arrive at home, if not planning to cook them immediately.

If they smell strongly fresh, they’re probably particularly fresh. They should smell slightly salty and fishy but not with a an overwhelming fish smell.

Mussels that have open shells could be dead, and thus dangerous to consume. If the mussels are still alive, give them a tap on the shell.

If they close up, they’re still good to eat. If they don’t close, discard them.

You can tell if mussels are bad if:

  • The shells are cracked or broken
  • The shells are open and the mussel meat is dried out
  • The mussels have an ammonia smell
  • The mussels have a slimy film on their exterior

If any of these things are true, it’s best to discard the mussel. Cooking won’t necessarily make a bad mussel safe to eat.

When in doubt, it’s always better to be safe than sorry when it comes to seafood!

When cleaning mussels, scrub them well under cold water to remove any dirt or debris. Use a stiff brush if necessary.

You can also debeard mussels by giving them a good tug – the beard is a stringy substance attached to the shell that helps the mussel attach to rocks.

Why can’t you eat mussels that don’t open?

Mussels that are not opened were dead from the beginning and they are not safe to consume.

Every mussel needs to be opened gently for eating, however in the event that the shell is tightly sealed that you require an crowbar to open it, that indicates that the shell is not good.

If you do not have a crowbar, then you can use a knife to pry it open. If the mussel is already dead, there is a possibility that it has been contaminated by bacteria which can cause food poisoning.

Mussels are filter feeders and they live in water. As they filter water for food, they also absorb toxins and pollutants that are present in the water.

These pollutants can be harmful to humans if consumed, which is why it is important to only eat mussels that are alive and well.

If you’re ever unsure about whether or not a mussel is safe to eat, it’s always better to err on the side of caution and throw it out.

It’s not worth risking your health for a mussel that may not be edible.

Do mussels open in the fridge?

Ideally, you should cook and prepare the mussels as soon as soon as you can, but in the event that they’re fresh, they can be kept overnight and even for an entire day.

If the mussels are opened then give them a squeeze and throw away any that remain open or with damaged shells.

You can store the mussels in the fridge, either in their shells or out of them. If you’re keeping them in their shells, make sure they’re covered with a damp cloth or paper towel so they don’t dry out.

If you’re taking them out of their shells, put them in an airtight container filled with cold water. Change the water every 12 hours to keep the mussels fresh.

When you’re ready to cook the mussels, give them a final rinse and scrub under cold water to remove any dirt or grit that may have accumulated.

Mussels are now ready to be steamed! Add them to a pot of boiling water and cook until they open up, which should take about five minutes.

How long does it take to get food poisoning from mussels?

The symptoms of shellfish poisoning can be seen 4 to 48 hours after eating the shellfish and can include: Nausea. Vomiting. Diarrhea.

Abdominal cramps. Fever. Chills. Symptoms usually last for 24 to 72 hours, but can last up to a week in some cases.

If you experience any of these symptoms after eating shellfish, it is important to see a doctor as soon as possible, as some types of shellfish poisoning can be life-threatening.

It is unclear exactly how long it takes to get food poisoning from mussels specifically, as there are many variables that can affect this, such as the type of mussel consumed and the person’s individual sensitivity to the toxins present in mussels.

Can you keep mussels in the fridge overnight?

Place the colander in an ice-filled bowl, so that the ice is able to drain away when it melts.

Don’t let the mussels be submerged or they’ll drown. Keep the mussels in the refrigerator or in a cooler, and they should be safe for at most 24 hours.

You can also keep them alive for a bit longer by storing them in a bucket of seawater.

Change the water every 12 hours, and don’t let the mussels sit in their own juices, as this will kill them.

With this method, you can usually keep mussels alive for up to 48 hours. If you have any mussels that die, discard them immediately.

Do not eat any mussels that do not open when cooked, as they may be spoiled. When in doubt, throw it out!

Now that you know how to store mussels, go forth and enjoy these delicious seafood treats!

Pair your fresh mussels with a glass of white wine for the ultimate dining experience.

Can you reheat mussels the next day?

To ensure your safety and for the highest quality of your food, make sure you choose mussels that are sealed.

Instead of throwing away any leftover mussels, store them in the refrigerator to then reheat them.

They are prone to dry out after being heated, but you should do it slowly. Place them in a skillet over low heat and add some water or broth to keep them moist.

You can also use wine, beer, or cider. It’s important not to overcook mussels as they will become tough, so reheat until they are just warm throughout.

If you’re looking for an easy seafood dinner option, try mussels! They cook quickly and don’t require much prep work.

Plus, they’re relatively inexpensive compared to other seafood options. Mussels can be steamed, grilled, or even baked.

And if you have leftovers, you can reheat them the next day. Just make sure to choose mussels that are still sealed and reheat slowly to avoid drying them out. Enjoy!

How long do mussels live for?

Most mussels can live for 60-70 years in an environment that is healthy. The oldest recorded mussel was 125 years old!

The lifespan of a mussel is determined by many different factors such as water quality and food availability.

However, the biggest threat to mussels is humans.

Humans are polluting the waters that mussels live in and we are also eating them!

Mussels are a delicious seafood but they are becoming harder to find because of overfishing.

We need to be careful with how we treat our oceans if we want to keep eating seafood like mussels for years to come.

Can you taste if a mussel is bad?

The mussel needs to get removed from the shell using an fork and consumed by mouth in one go.

However, the ultimate the judge of a good mussel is the palate of the person who is eating.

Therefore, if the mussel is not taste delicious, no matter if it’s opened or sealed the case should not be eaten. Open-and-closed case!

If you have any doubts about a mussel, don’t take the risk. There are plenty of other seafood options to choose from.


Overall, it is quite difficult to tell if mussels are bad after cooking. The best way to ensure that they are cooked properly is to use a food thermometer.

If the internal temperature of the mussel reaches 165 degrees Fahrenheit, then it is safe to eat.

Additionally, you can also look for signs of spoilage, such as an off-putting smell or discoloration.

If you notice either of these things, it is best to discard the mussel.

Finally, remember that cooked mussels should be eaten within two days.

After that time, they will start to spoil and can cause food poisoning.
