Yes, mold on cheese can make you sick if it’s a harmful variety or the cheese is not meant to be moldy. Consuming moldy cheese can lead to digestive issues and allergic reactions. It’s important to distinguish between safe, edible mold in cheeses like blue cheese and harmful mold, which is typically fuzzy and discolored.
Understanding Mold on Cheese

Different Types of Mold: Beneficial vs Harmful
Cheese lovers, did you know that not all molds are created equal? Some molds are great for cheese, while others can be harmful.
Beneficial molds are used to develop the flavor and texture of certain cheeses. A famous example is Penicillium roqueforti, which gives blue cheese its distinctive taste.
On the flip side, harmful molds can spoil cheese and pose health risks. These unwanted molds may produce toxins and can cause the cheese to smell bad and taste awful.
It’s important to know the difference to enjoy cheese safely.
Role of Mold in Cheese Making and Aging
In the world of cheese making, mold is a star! It plays a huge role in aging cheese to perfection.
During the aging process, mold helps to break down the cheese’s components, leading to a depth of flavor and a creamy texture that we all love. For example, Brie and Camembert have white mold rinds that are totally safe to eat.
This mold is not just for looks; it’s a key part of what makes these cheeses so special.
Types of Cheese that Commonly Have Mold
Many cheeses are famous for their mold. Blue-veined cheeses like Gorgonzola, Stilton, and Roquefort have beautiful blue or green marbling thanks to mold.
Soft cheeses like Brie and Camembert have a white, edible mold rind. These molds are not only safe but also essential for the character and flavor profile of these cheeses.
Remember, these molds are specially selected for cheese making and are perfectly fine to enjoy.
Difference Between Safe Mold and Spoilage Mold
So, how can you tell safe mold from bad mold? Safe mold on cheese is usually uniform in color and texture. It’s part of the cheese’s design.
Harmful mold, however, can look fuzzy and can be a range of colors like green, black, white, or even pink.
If you see mold on cheese that’s not supposed to have it, that’s a red flag. It could mean the cheese has gone bad or has been stored improperly.
Health Implications of Consuming Moldy Cheese

Potential Health Risks Associated with Harmful Molds
Eating harmful molds can be a health no-no. These molds can produce substances called mycotoxins that can make you feel sick.
They can lead to nausea, vomiting, and diarrhea. For people with mold allergies, eating moldy cheese can trigger sneezing, coughing, and breathing difficulties.
It’s always better to be safe and steer clear of cheese that looks or smells off.
Mycotoxins and Their Effects on Health
Mycotoxins are sneaky toxins that harmful molds produce. They can cause a range of health problems if you eat them.
Long-term exposure to mycotoxins can even affect your immune system and liver. Not all molds make mycotoxins, but it’s best to avoid moldy cheese unless the mold is meant to be there.
Symptoms of Mold-Related Food Poisoning
If you eat cheese with harmful mold, you might get food poisoning. Signs of this can include stomach pains, diarrhea, vomiting, and sometimes even headaches and fever.
These symptoms can pop up quickly after eating the bad cheese. If you think you have food poisoning from moldy cheese, it’s a good idea to talk to a doctor.
Populations More Vulnerable to Mold-Related Illnesses
Some people need to be extra careful with moldy cheese. Babies, pregnant women, older adults, and anyone with a weakened immune system should avoid it.
These groups are more at risk for getting sick from harmful molds. It’s always better to be on the safe side and choose cheese that’s mold-free, unless it’s a type with safe, edible mold.
Safe Practices for Handling and Consuming Cheese with Mold

Guidelines for When to Cut Off Mold and When to Discard Cheese
Can you just cut off the moldy part and eat the rest? Sometimes, yes! If you see mold on hard cheese like cheddar, you can cut off at least an inch around and below the mold spot.
But if the cheese is soft, like cottage cheese or cream cheese, it’s best to throw it away. Mold can spread in these types of cheese even if you can’t see it.
Safe Storage Practices to Prevent Unwanted Mold Growth
Keep your cheese happy and mold-free by storing it right. Wrap it up tight in wax paper or cheese paper and then put it in a plastic bag.
This keeps the cheese from drying out and stops mold from getting in. Keep your fridge temperature below 40°F (4°C) to slow down mold growth.
And don’t forget to keep cheese away from raw meats to prevent any cross-contamination.
Tips for Identifying When Cheese is No Longer Safe to Eat
How do you know when cheese has gone bad? Look for signs like mold that’s not supposed to be there, a sour smell, or a slimy texture.
If the cheese has any of these signs, it’s time to say goodbye. It’s better to be safe than sorry, so when in doubt, throw it out.
Preventing Cross-Contamination with Other Foods
Keep your kitchen safe by avoiding cross-contamination. Use different cutting boards for cheese and other foods, especially raw meats.
Make sure to clean your knife if you cut off mold from cheese before using it on another food.
And always wash your hands after handling moldy cheese. These simple steps can help keep you and your food safe.
