Is Eating Slimy Mushrooms Safe?

Eating slimy ones can be hazardous. While certain mushrooms can be poisonous, others are naturally slimy and safe to eat.

It’s meal prep time, and you find a package of mushrooms in your fridge that would be ideal for your omelet and side dish, only to discover that the item has been there for days. You examine the mushrooms; they appear to be in fair condition, with only a small sheen on the surface. You might question if these slimy mushrooms are still edible. Here are some important things to think about:

• Identification: Prior to eating any mushrooms, make sure they are correctly identified. When cooked, some edible mushrooms—such as some species of Pleurotus, or oyster mushrooms—can become a little slimy.
• Toxicity: Some slimy mushrooms, such some Amanita and Cortinarius species, have the potential to be extremely toxic and deadly.
• Freshness: Because they may contain dangerous bacteria, mushrooms that have spoiled and turned slimy should not be consumed.
• Cooking: While cooking can frequently lessen the sliminess of mushrooms, it does not render hazardous mushrooms safe for consumption.

How long do mushrooms last in the refrigerator?

Fresh mushrooms keep for one to three days at room temperature. Storing them in the refrigerator from the date of purchase can keep them fresh for three to seven days.

According to the USDA Foodkeeper App, fresh mushrooms can be frozen for 10 to 12 months after purchase. Mushrooms have a high water content, so thawed mushrooms may become mushy.

There are a few elements that influence how long they last:

• Their size: Larger mushrooms, including cremini and portobello, last longer than smaller mushrooms.
• Their form: Sliced mushrooms have a shorter shelf life than whole mushrooms because their interior contents are exposed to air.
• How are they stored: Mushrooms stay longer when stored in a paper bag than in a plastic bag in the crisp drawer of the fridge because the former allows for airflow.extra moisture is absorbed.

Why do mushrooms become slimy?

The way mushrooms are stored has a direct impact on their shelf life. Even after harvest, the fungi continue to live.

They do not have a peel like apples and pears, which protects the mushrooms from drying out and decomposing. When they are placed inside plastic packaging or a paper bag, the moisture contained inside provides an ideal environment for microbial growth, including bacteria and molds. So, the metallic sheen you perceive on mushrooms indicates rotting.

Can you eat slimy mushrooms?

As much as you want to save them for your favorite risotto recipe, it is best to avoid eating slimy mushrooms because the slime indicates that the mushrooms have begun to rot.

While a few slimy mushrooms may not make you sick, any meal tainted with dangerous bacteria may. After harvesting, mushrooms can get contaminated with dangerous bacteria such as Listeria monocytogenes. Listeria is a bacteria that, according to the CDC, can infect a variety of foods, including soft cheeses, deli meats, and raw milk products.

While mushrooms are professionally grown in pasteurized manure composts, which considerably inhibit listeria growth, they can become infected with harmful germs during post-harvesting and processing, when they are sorted and packed for distribution to retailers.

How to Know If Mushrooms Have Gone Bad

Examine each slimy mushroom carefully before deciding whether or not to eat it. Are they discolored or shriveled, or do the gills on the mushroom’s underside appear damp and collapsed?

Check the bottom of the package if you retained the mushrooms in their original packaging rather than putting them in a paper bag. When mushrooms begin to spoil, their cell walls separate, releasing moisture.

Also, sniff the mushrooms – do they have an unpleasant odor? Fresh mushrooms have a mild, earthy scent. If they smell bad, even if there is only a little slime, it’s time to toss them away.

How about washing and cooking them?

When handling mushrooms, whether slimy or not, it is better to avoid cleaning and washing them until you are ready to cook with them. Always wash your hands before and after handling the items, and use a clean cutting board.

While it is not suggested, if you insist on having slimy mushrooms, you can wash them off and prepare them. Perform a taste test to see if the mushrooms provide their naturally occurring umami qualities. If they taste harsh or unpleasant, discard the rest.

Because mushrooms may contain disease-causing germs, they are better consumed cooked. If you place the mushrooms in a mixed dish, sauté the ingredients reaching a temperature of 165 degrees Fahrenheit inside.

Are mushrooms that have rotted toxic?

You may have some nausea, diarrhea, and/or vomiting, and you’ll probably feel a little nauseous if by “bad” you mean an otherwise edible mushroom that’s past its prime. If by “bad” you mean that you consumed a toxic mushroom, then the term might apply to a variety of symptoms, including death.

How may the sliminess of mushrooms be prevented?

Additionally, introducing too much moisture—either by washing your mushrooms before storing them or dabbing them with a paper towel—does not help your fungi grow. Since grocery store paper cartons with perforated plastic wrap are usually made to allow airflow, you can reuse the original packing.

It is advised to stay away from eating a mushroom if you are unsure of its type. When foraging, think about speaking with a professional or referring to a trustworthy field guide.
