Sometimes when I am at the grocery store, I have the best of intentions with my meal planning but then life gets in the way. Have you ever opened the fridge and realized that you have something in there that you need to use but then wondered if it’s still good? This happens to me all of the time. That is why I had to find out for sure how long do mushrooms last?
Raw mushrooms can last up to 10 days in the refrigerator but proper storage is important. Sliced mushrooms can last up to 7 days in the fridge. Cooked mushrooms can last up to 10 days.
You can generally tell if a mushroom has gone bad by how it feels. If it feels slimy and sticky it is probably not a mushroom that you want to eat. Another sign of a mushroom going bad is if it is discolored, looks bruised or has brown spots. Also, if your mushrooms are looking shriveled that is a sign that it has definitely dehydrated and may not be tasty. Finally, smell your mushrooms because a spoiled mushroom will smell sour or a bit like ammonia.
Tip: When you buy your mushrooms fresh from the store make a note of their condition. This will help you keep a visual gauge on the discoloration as they age in your fridge. White mushrooms should be nearly blemish free with well-rounded white caps and no brown on the end of the stems. Portabellas: uniform brown color without blemishes, no slimy-looking stems, preferably with a tight cap.
Can you get sick from eating old mushrooms?

What’s the best way to store fresh mushrooms?
Make sure that your mushrooms are not fully wrapped in plastic. They need some air to breath and something that will absorb excess moisture.
