Is Green Mold On Cheese Dangerous

Is green mold on cheese dangerous. Cheese is a fundamental dairy product that comes in numerous types. It’s made up of milk that has been separated into two components: solid (fats and proteins).

Although there are numerous types of cheese, they all go through the same basic preparation process.

Milk is used to make cheese, and it goes through an aging process before being produced into the finished cheese product. Ageing is a complex process, and whether aged or moldy cheese are edible is a source of debate.

Bacteria are often used in the process of making cheese. Yet, the moulds (or fungus) employed are particular varieties in certain cases, such as Roquefort, Camembert, brie, or blue cheese.

Any food, including cheese, can be moldy. The causes of cheese molding range from nutritional to hygiene. Mold requires a lot of nutrients to grow, and cheese provides them.

Moreover, by soaking the cheese in salty water, which dries out the rind and makes it less enticing for mold to grow, there are various ways to keep mold off the cheese.

Mold and bacteria, on the other hand, are frequently mistaken as being the same. Mold is not common in most cheeses, although it is common in white, blue, and green penicillium mold.

What is mold?

Molds are fungus that spore and generate spores. They can be found anywhere in the environment, from your refrigerator to insects and water, and prefer warm, moist conditions.

In the majority of foods, mold is a indication of spoilage. Green, white, black, blue, or gray tend to be fuzzy and greenish.

It usually appears on the surface of the food when it begins to grow, with its roots extending deep into the food. It gives the food a sour or “off” odor by altering its appearance and smell.

Although molds are generally harmful to consume, certain kinds are utilized in cheesemaking to create flavor and texture. These types of mushrooms are totally safe to eat.

MOLD: Mold is a fuzzy, off-color spore that produces fungus. Some types of fungus are used to make certain cheeses, despite the fact that it’s typically a indication of spoilage when it grows on food.

Why can mold be harmful?


There are a variety of molds available again. Others may make you quite ill, while some will do nothing. The USDA warns that certain molds may cause allergic responses and breathing difficulties.

Some molds, under the right circumstances, may create “mycotoxins,” which are harmful chemicals that may make you sick and even kill you.

Good mold vs. bad mold

Cheese, in and of itself, is mold in certain ways. Several of the cheesemaking molds are also wonderful.

That white mold growth on soft-rind cheeses like Brie or Camembert, or the blue veins in your favorite Gorgonzola, is a thick coating. So, really, none of the molds that might grow on your cheeses will make you sick.

Moreover, they might have an adverse effect on the flavor of your cheese. In order to avoid wasting any yummy pieces, it’s essential to learn how to control the mold on your cheeses.

How does cheese get moldy?

Some cheeses are meant to be moldy, and it’s OK to eat those molds, says Jane Ziegler, D.C.N., R.D., L.D.N., associate professor and director of the Department of Clinical and Preventive Nutrition Sciences at Rutgers University.

She adds, “The development of Penicillium roqueforti spores causes blue-veined cheese to develop, such as Roquefort, Gorgonzola, and Stilton.

A internal and a surface mold may exist in other cheeses. These cheeses are safe to eat since they are pasteurized.

Mold spores, on the other hand, may grow in the air or water if they attach to your cheese.

Mould can collect and grow on the food’s surface when moisture is present, and ventilation allows for mold exposure, Detwiler says.

“Mostly these are invisible to the naked eye, but when one can see mold, strong roots have already grown.”

Main Types of Mold prepared Cheese


1. Soft-ripened

The smooth and thin rind (outer texture) of semi-ripe cheese is well-known.

The cheese is typically sprayed with the mould, which allows it to develop from the outside and form its characteristic rind. The most well-known varieties of this kind of cheese are Brie and Camembert.

2. Washed-rind

The exterior texture of washed-rind cheese is similar to that of soft-ripened cheese. The surface of the cheese is washed with saltwater or another mold-bearing substance on a regular basis to prepare it.

The cheese’s aroma and texture are improved by washing it inwards. Smear-ripened cheese is a softer version of washed-rind cheese.

Washed-rind cheese includes bricked, Limburger, and Munster.

3. Blue Cheese

During the early stage of cheese production, specific strains of penicillium mould are injected to produce blue cheese.

To allow oxygen access deep inside the interior, the cheese is often spiked during the early manufacturing stages. The blue color and flavor of spiking are what give the blue cheese its unique hue.

The most common types of blue cheese include Roquefort, Gorgonzola, and Stilton.

Is moldy cheese safe to eat?

Spoiled cheese isn’t always moldy.

The molds that sprout on your old cheese and bread are not the same as the ones used to make particular varieties.

It is safe to consume those who make cheese. Blue veins within the cheese or a thick, white rind on the exterior — rather than ordinary mold, which has a fuzzy growth that ranges in color from white to green.

Odor can also be a mold indicator, in addition to appearance. It’s also a good idea to smell the cheese after you purchase to establish a baseline since some cheese is naturally stinky.

You can check the freshness of the product in the future using this method.

It’s worth noting that mold-grown cheeses may also carry dangerous spores. Those that develop on different foods look a lot like them.

Is green mold on cheese dangerous, should I throw it away?

Moldy soft cheeses, such as cottage cheese, cream cheese, and ricotta, should be tossed. Any kind of shredded, crumbled, or sliced cheese is subject to the same rule.

The mold can spread threads throughout the cheese, contamining more than you see, with these cheeses.

Harmful bacteria, such as listeria, brucella, salmonella, and E. coli., may also be present. coli may develop alongside the mold.

Hard and semisoft cheeses, such as cheddar, colby, Parmesan, and Swiss, are generally impervious to mold.

So you can eat the remainder of the cheese by cutting away the moldy section. At least 1 inch (2.5 centimeters) above and below the moldy area should be cut off.

Make sure you keep the cheese mold away from the knife so it does not contaminate other areas.


Of course, not all mold are dangerous. Cheese varieties like Brie and Camembert are made using specific types of mold. Adults who are healthy may consume these molds.

People with decreased immune systems, senior adults, pregnant women, babies, and young children should avoid these cheeses as well as other soft cheeses and cheeses made with unpasteurized milk.

The safest option is to throw away any cheese that you’re not sure about or what to do if it grows mold.

Health Risks of Moldy Cheese

1. Mycotoxin Exposure

The term “mycotoxin” refers to a group of fungal toxins. Chronic exposure to mycotoxins has been linked to cancer, liver damage, and immune suppression, according to certain research.

Aflatoxin is a notorious hepatotoxic chemical created by a fungus that may be lethal in high doses and induce severe liver damage.

Human Ergotism is caused by other noxious chemicals such as Ergot Alkaloids. This condition necessitates urgent medical attention since it causes severe spasms.

2. Food Poisoning

Toxins can be found in several varieties of moldy cheese. Food poisoning can result from acute exposure to certain chemicals. Nausea and tiredness are common symptoms that may eventually lead to chronic diarrhoea.

If you have nausea, vomiting, or diarrhoea after suspecting you’ve eaten moldy cheese, see a doctor right away.

3. Mold Allergy

Everyone may be at risk of mold exposure. Mold spores can cause allergic responses in some people, and they are more sensitive to atmospheric allergens.

Asthma sufferers, for example, should be careful when handling moldy materials. Mold can also worsen symptoms, according to certain research.

4. Presence of Other Harmful Microorganisms

Other microorganisms, such as bacteria, thrive in the environment that allows mold growth. Also, harmful bacteria such as E. coli The food and the mould may also be colonized by coli and Salmonella.

Therefore, you should not eat foods that are uncertain about having mold since such microorganisms may cause severe illness.

How can I prevent cheese from molding?

The best way to prevent cheese from molding is to store it properly and consume it within a reasonable time period. Wrap your cheese in specialty cheese packaging or a sheet of parchment packaging to store it.

The type of cheese and the date you purchased it are both written on the label.

Keep it in a drawer in your fridge, which will maintain consistent temperatures and humidity. You can store cheese in a dedicated wine fridge, which is preferable for the cheese since the temperatures are less chilly.

The best way to store your cheese safely


Every few months, the USDA recommends cleaning your refrigerator with a baking soda solution or a bleach solution to kill off mold spores that may be hiding inside.

According to the USDA, you should also keep your cheese wrapped in plastic wrap and avoid leaving it out for more than two hours at a time.

Detwiler has a trick that you might want to try if you’re really serious about your cheese storage:

To keep the cheese fresh, wrap a hard or soft cheese in fresh parchment or waxed paper after each use. “These breathable materials prevent mold-causing moisture from collecting on the surface without drying it out,” he says.

Bottom line: It is best to pitch moldy cheese if you are unsure of what kind or how to dispose of it. Throw it out if you’re not sure.

Health Benefits of Cheese

1. Rich Protein Source

Proteins may be found in cheese. Cheese is a excellent source of proteins and is often difficult for vegetarians to achieve an adequate protein intake.

The fact that cheese contains the fat and proteins part of milk, which has been separated from the water, is directly related to its higher protein content.

2. Enhances Bone Development

Cheese is one of the milk products with a high calcium content. Calcium and phosphorus, as well as important minerals for bone development, are extremely high in cheese.

Moreover, if you don’t get enough calcium, your bones will absorb it, weakening them. As a result, cheese consumption aids in calcium intake by helping to keep it healthy.

3. Improves Immunity

According to certain research, the probiotic properties of cheese help strengthen the immune system, allowing people to fight off any illnesses and illnesses.

4. Lowers Cholesterol

Many heart conditions are linked to cholesterol. As a result, anything high in fat is assumed to raise cholesterol levels, according to most people.

Cheese consumption has been linked to lower cholesterol levels in certain research. Cheese has a high calcium concentration, which decreases the amount of fat absorbed by the body.

What can happen if you eat moldy cheese?

The variety is incredible, and it all depends on whether the mold is carrying bacteria and how severe the symptoms are. You can’t tell from looking at it. This is how Detwiler predicts possible outcomes:

Worst-case scenario: Nothing. You might experience indigestion or a bad taste.
You might experience a mild allergic response, get sick from food, or have respiratory concerns in the interim.


You might be sent to the hospital, have dialysis treatment, or even die in the worst-case scenario. Immunocompromised people are more likely to face this danger, according to Detwiler.

It is preferable to throw the cheese, particularly when there are children and people at high-risk in the family, Ziegler says.

When it comes to soft cheeses, shreddeds, or sliced cheeses, Ziegler says that’s especially true. “Soft cheeses have a high moisture content,” she explains. “They can be contaminated well beyond the surface of the moldy area.”

According to Detwiler, if your cheese is hard or semi-soft, such as cheddar, Parmesan, or Swiss, you may be able to scrape off the moldy portion and enjoy the remainder of the cheese.

“Keep the knife out of the mold so it doesn’t contaminate other sections of the cheese,” he advises.
