How to Tell If A Mushroom Is Bad?
It’s a key cooking skill if you know how to tell if mushrooms are bad. Eating spoiled or rotten mushrooms can cause gastrointestinal illness and even poisoning. It’s not the mushrooms that will get you – it’s the microbes that eventually colonize and take over mushrooms once they are spoiled. Below are some ways to determine if mushrooms have spoiled while in storage:
- Check the entire mushroom and see if the surface is already wrinkling or if there are already shriveled areas. Shriveling is the first sign that mushrooms are beginning to degrade. As much as possible, eat fresh mushrooms and try to consume them before they begin to shrivel up.
- Inspect the surface of the mushrooms and see if there are any brown or black spots. Any discolorations will signal something wrong with your mushrooms, and you should likely toss them.
- Slimy mushrooms are abnormal, and they should not be eaten. The best mushrooms have good color, firm flesh, and do not have any slime. Slime is a sign of decomposition.
- Smell your mushrooms. Fresh mushrooms have very little smell. There might be a little earthy smell, but that’s it. If you smell sourness or any strange stink, then toss your mushrooms in the bin.
Store-bought mushrooms should always be kept for a maximum of ten days only, even in the fridge. This applies to portabella mushrooms, cremini, and white mushrooms as well. Mushrooms that have already been displayed for a week in any store will likely spoil quickly once brought home.
