Mushrooms are a versatile ingredient that can be used in a variety of dishes. However, it is important to ensure that they are safe to consume. One of the key indicators of spoiled mushrooms is a fishy smell. Fresh mushrooms should have a slightly sweet and earthy aroma, and any deviation from this, such as a pungent or sour odour, indicates spoilage. Mushrooms can also exhibit other signs of deterioration, including a slimy texture, wrinkling, discolouration, and the presence of dark spots or mould. It is crucial to inspect mushrooms carefully before consumption to avoid any potential health risks associated with consuming spoiled food.

What You'll Learn
Mushrooms with a fishy smell are unsafe to eat
Mushrooms are incredibly versatile and nutritious, but they can quickly turn bad. One of the most obvious signs of spoilage is a fishy smell. If your mushrooms have developed a fishy aroma, it's a clear indication that they have gone bad and are unsafe to eat. This smell is caused by an excessive amount of bacteria on the surface of the mushrooms, which can be dangerous if consumed.
Fresh mushrooms should have a pleasant, earthy, and slightly sweet aroma. A fishy smell is a stark contrast to this and is a sure sign that your mushrooms are no longer edible. In addition to the smell, you may also notice other signs of spoilage, such as a slimy texture, wrinkles, or discolouration. These mushrooms have likely been left in the refrigerator for too long, leading to bacterial growth and spoilage.
It's important to inspect your mushrooms before cooking or consuming them. Give them a whiff to check for any unusual odours and examine their texture and appearance. Fresh mushrooms should be firm, springy, and plump. If they feel soft, soggy, or spongy, it's a sign that they have started to decompose and are unsafe to eat.
To extend the shelf life of your mushrooms, proper storage is key. It's best to purchase whole mushrooms instead of pre-sliced ones as they tend to last longer. Store them in a paper bag in the refrigerator crisper drawer. The paper bag allows air to circulate, keeping the mushrooms fresh, while the paper towel absorbs excess moisture, preventing the growth of slime. With proper storage, mushrooms can last up to 7-10 days in the refrigerator.
In conclusion, if your mushrooms smell fishy, it's best to discard them immediately. Mushrooms with a fishy smell are unsafe to eat due to the presence of excessive bacteria. To prevent waste, it's advisable to inspect your mushrooms regularly and use them within the first week of purchase, as their quality tends to decrease after that.

A fishy smell is caused by an overwhelming amount of bad bacteria
Mushrooms are fungi that are typically covered in a thin layer of dirt when you buy them. This can make it tricky to tell if they've gone bad. However, a fishy smell is a clear indication that they are no longer safe to eat.
Mushrooms can go bad just like any other food. They are highly perishable and can last about 7-10 days in the fridge. Fresh mushrooms should have a slightly sweet and earthy smell. If they smell fishy or pungent, it is because they are now spoiled and have been colonized by bacteria. Different bacteria cause different odors, so bad mushrooms may give off various strange smells.
Mushrooms that have been left in the refrigerator for too long often become slimy and are more likely to be covered in bacteria. If you can see or feel that the mushrooms are wet, sticky, or slippery, they are no longer edible. Fresh mushrooms should look and feel dry, crisp, and plump.

Fresh mushrooms should be dry, firm, and smooth
Mushrooms are fungi, so it can be difficult to tell if they are spoiling or are just fungusy. However, the texture is usually a good indicator of their freshness. Fresh mushrooms should be firm and plump. If your mushrooms feel soft, soggy, spongy, or floppy, they have started to decompose and are no longer safe to eat.
Fresh mushrooms typically last about 7-10 days in the fridge. However, they may spoil before then, depending on how long they have been sitting out at room temperature. Aim to use fresh mushrooms within 3-4 days of purchasing. If you store them correctly in an open brown paper bag in the fridge crisper drawer, they will last longer. The paper bag will absorb excess moisture and allow air to flow freely, keeping your mushrooms fresh.
If your mushrooms smell fishy, it means they are too far gone to eat. Mushrooms that smell fishy are spoiled. They may also be wrinkled or shrivelled, have brown spots or discolouration, and grow mould.

Bad mushrooms are slimy, wrinkled, and discoloured
Mushrooms are delicate and can go bad quickly. Bad mushrooms may be slimy, wrinkled, and discoloured.
Mushrooms are fungi, and when fresh, they are typically covered in a thin layer of dirt. They usually have a slightly sweet and earthy smell. However, when they go bad, they can develop an unpleasant odour, becoming pungent, musky, sour, or even fishy.
If mushrooms are slimy, it means that bacteria are breaking them down, and they are no longer edible. Sliminess is often the result of keeping mushrooms in the fridge for too long. Mushrooms have a high water content, and when exposed to excess moisture, they can become slimy and discoloured. Therefore, it is best to store mushrooms in a paper bag in the fridge to absorb excess moisture and allow airflow.
Wrinkles on mushrooms indicate that they are getting old and dehydrated. If they have just started to wrinkle and show no other signs of spoilage, they can still be used, but they will need to be rehydrated. However, if the mushrooms have many wrinkles and look shrivelled, they are too far gone and should not be eaten.
Discolouration is another sign of spoilage. Mushrooms can develop dark spots or become darker overall, especially white or light-coloured varieties. If the spots are minor, the mushrooms can still be consumed, but if they are completely covered in spots, it is best to discard them.
In summary, bad mushrooms will likely be slimy, wrinkled, and discoloured, and may also have a fishy or otherwise unpleasant odour. To prevent mushrooms from going bad, it is important to store them properly in a paper bag in the fridge and consume them within a few days of purchase.

Properly stored mushrooms last longer
Mushrooms are a tasty and nutritious addition to any meal, but they can go bad quickly. Fresh mushrooms typically last about 7-10 days in the fridge, but they may spoil before then depending on how long they've been sitting out at room temperature or how they are stored.
To make your mushrooms last longer, it's important to store them correctly. Mushrooms have a high water content, so storing them in their supermarket packaging can trap moisture and cause them to spoil more quickly. The best way to store mushrooms is in a breathable container in the refrigerator. A brown paper bag works great, and you can also add a paper towel to absorb excess moisture. The bottom shelf of the fridge is best, as the crisper drawer tends to be too humid for mushrooms.
If you're not planning on using your mushrooms within a few days, you can also freeze them. Spread them out on a cookie sheet and flash-freeze them until they are frozen solid. Then, transfer them to a freezer-safe container, where they will last for up to 3 months.
To tell if your mushrooms have gone bad, look for any wrinkles, dark spots, or a slimy coating. Fresh mushrooms should be firm, dry, and plump, so if they feel soft, soggy, or spongy, that's another sign they've gone bad. Give them a whiff, too—if they smell fishy, pungent, or sour, it's time to toss them.
