Mushrooms are a versatile ingredient, adding an earthy, umami flavour to a variety of dishes. However, they are highly perishable and can quickly spoil. So, how do you know if spotty mushrooms are safe to eat? Fresh mushrooms should be dry, crisp, and firm to the touch, with an even colour and a subtle, earthy scent. If they have developed brown spots, slime, or a strong smell, they are no longer safe to eat. Even a small amount of mould can indicate the presence of harmful bacteria, so it is important to discard any questionable mushrooms. When in doubt, trust your senses and only eat mushrooms that look, feel, and smell fresh.

Fresh mushrooms should be dry, firm, and smooth
Mushrooms are a versatile ingredient that can add an earthy, umami flavour to a variety of dishes. However, they have a short shelf life and can quickly spoil. Fresh mushrooms should be dry, firm, and smooth, with a pleasantly earthy smell.
When buying or preparing mushrooms, it is important to inspect them for any signs of spoilage. Discolouration, such as brown or dark spots, is an indication that mushrooms are starting to go bad. Mushrooms should also be avoided if they appear slimy, sticky, or wet, as this indicates the presence of bacteria and the beginning of rot. Slimy mushrooms have likely been stored incorrectly or left in the fridge for too long.
To maintain freshness, mushrooms should be stored in the fridge in a breathable container or bag to prevent moisture build-up. It is recommended to use fresh mushrooms within 3 to 4 days of purchasing, as they can quickly degrade if not stored properly.
If mushrooms have only started to lose freshness, they can still be used in cooked dishes like soups, sauces, or chillies. However, if there are other signs of decomposition, such as an unpleasant odour, the mushrooms should be discarded. It is important to prioritise food safety and avoid consuming spoiled mushrooms, as they may contain bacteria that can cause food poisoning or botulism.
In summary, fresh mushrooms should be dry, firm, and smooth. When selecting mushrooms, it is crucial to inspect them visually and tactilely for any signs of spoilage and to store them properly to prolong their freshness.

Slimy, smelly, or mouldy mushrooms could make you sick
Mushrooms are a versatile ingredient that can add an earthy, umami flavour to a variety of dishes. However, it is important to be cautious when consuming mushrooms, as eating spoiled mushrooms can lead to food poisoning or botulism.
Mushrooms have a short shelf life and can quickly show signs of spoilage. One of the key indicators of spoiled mushrooms is a slimy texture. If the mushrooms have a coating of slime or feel wet and slippery, they should be discarded. This sliminess occurs when mushrooms have been stored incorrectly or left in the fridge for too long, and it indicates that the mushrooms are beginning to rot and are at risk of bacterial growth.
In addition to slime, other signs of spoilage include discolouration, bruises, and dark spots. Mushrooms should generally appear dry, crisp, and fresh, with a pleasantly subtle scent. If they exhibit an unpleasant or unusual odour, it is best to throw them out. Mushrooms that are soft, mushy, or shrivelled are also not ideal for consumption.
To prevent spoilage, it is recommended to store mushrooms in the fridge in a breathable container or bag to regulate moisture levels. Aim to use fresh mushrooms within 3 to 4 days of purchasing, as they can quickly degrade and develop signs of spoilage.
It is important to exercise caution when consuming mushrooms, especially wild mushrooms. If you are unsure about the safety of mushrooms, it is better to discard them than risk potential health hazards.

Mushrooms have a short shelf life and can spoil quickly
To prevent spoilage, mushrooms should be stored in the fridge in a breathable container or bag to prevent moisture build-up. They should be used within 3 to 4 days of purchase. Sliced mushrooms have a shorter shelf life than whole mushrooms due to their larger surface area. They usually last around 3 to 5 days in the fridge.
Discolouration is another sign that mushrooms are going bad. If mushrooms develop bruises or dark spots, it is best to discard them. However, moon-shaped marks are harmless indentations caused by the stalks pressing onto the caps during transit.
It is important to note that wild mushrooms require special caution. Do not attempt to determine whether wild mushrooms are edible or poisonous without the guidance of a trained mushroom identification professional.

Do not eat mushrooms you aren't 100% sure are safe
It is important to exercise extreme caution when consuming mushrooms in the wild. While some mushrooms with spots may be safe to eat, it is crucial to properly identify the mushroom before consumption. There are many varieties of mushrooms, and some that have spots may belong to toxic species. Even a small amount of certain toxic mushrooms, if ingested, can cause severe illness or even death.
It can be tricky to identify mushrooms, as some poisonous varieties can closely resemble edible ones. Moreover, the same species of mushroom can exhibit variations in appearance depending on its maturity, the local environment, and other factors. Therefore, it is crucial to be absolutely certain of a mushroom's edibility before consuming it. If you are unsure, it is always best to err on the side of caution and refrain from eating it.
One common misconception is that all mushrooms with spots are poisonous. While it is true that some toxic mushrooms may exhibit spots, this is not always the case. However, it is not worth risking your health to find out. If you are ever in doubt about a mushroom's safety, it is best to leave it alone.
Another important consideration is that the toxicity of some mushrooms can vary depending on the individual and the amount consumed. Even if a mushroom is generally considered edible, some people may have an allergic reaction or sensitivity to it. Therefore, it is important to always cook mushrooms properly and consume them in moderation, especially if you are trying a new variety for the first time.
In summary, when it comes to wild mushrooms, it is always better to be safe than sorry. If you are unsure about a mushroom's edibility, do not eat it. There are plenty of other safe and delicious mushroom varieties available in grocery stores and markets, so there is no need to take the risk with uncertain wild mushrooms. Your health and safety are always the top priorities.
Remember, if you ever suspect that you or someone you know has consumed a toxic mushroom, seek medical attention immediately, even if symptoms are mild. Prompt medical care can make a significant difference in the outcome of mushroom poisoning.
