The world of cheese is a vast and wondrous place, with a staggering array of textures, flavors, and aromas to explore. From the creamy richness of brie to the tangy zip of feta, there’s a type of cheese out there to suit every taste and preference. However, amidst all the excitement and enthusiasm for artisanal and farm-to-table cheeses, there’s a growing concern about the safety of unpasteurized cheese. In this article, we’ll delve into the reasons why unpasteurized cheese can be bad for you, and why it’s essential to exercise caution when consuming these types of cheeses.
What is Unpasteurized Cheese?
Before we dive into the potential risks associated with unpasteurized cheese, it’s essential to understand what it is and how it’s made. Unpasteurized cheese, also known as raw milk cheese, is made from milk that hasn’t been heat-treated to kill off bacteria and other microorganisms. This means that the milk used to produce unpasteurized cheese can contain a range of bacteria, including some that can be harmful to humans.
The Risks of Unpasteurized Cheese
So, why is unpasteurized cheese bad for you? The primary concern is the risk of foodborne illness. Unpasteurized cheese can contain a range of pathogens, including:
- E. coli: A type of bacteria that can cause severe food poisoning, including symptoms like diarrhea, vomiting, and abdominal cramps.
- Salmonella: A type of bacteria that can cause food poisoning, including symptoms like diarrhea, fever, and abdominal cramps.
- Listeria: A type of bacteria that can cause food poisoning, including symptoms like fever, headache, and stiffness.
- Brucella: A type of bacteria that can cause brucellosis, a serious infection that can lead to symptoms like fever, headache, and muscle pain.
These pathogens can be present in the milk used to produce unpasteurized cheese, and can survive the cheese-making process. When consumed, these pathogens can cause a range of illnesses, from mild to severe.
Who’s at Risk?
While anyone can get sick from consuming unpasteurized cheese, some groups are more vulnerable than others. These include:
- Pregnant women: Pregnant women are more susceptible to foodborne illness, and can pass on infections to their unborn babies.
- Young children: Young children are more vulnerable to foodborne illness, and can experience severe symptoms.
- Older adults: Older adults may have weakened immune systems, making them more susceptible to foodborne illness.
- People with weakened immune systems: People with conditions like HIV/AIDS, cancer, or taking immunosuppressive medications may be more vulnerable to foodborne illness.
The Benefits of Pasteurization
So, why do we pasteurize milk and cheese in the first place? Pasteurization is a process that involves heating milk to a high temperature to kill off bacteria and other microorganisms. This process has several benefits, including:
- Killing off pathogens: Pasteurization can kill off pathogens like E. coli, Salmonella, and Listeria, making milk and cheese safer to consume.
- Extending shelf life: Pasteurization can help extend the shelf life of milk and cheese by reducing the risk of spoilage.
- Improving flavor and texture: Pasteurization can help improve the flavor and texture of milk and cheese by reducing the risk of off-flavors and textures.
Is All Unpasteurized Cheese Bad?
While unpasteurized cheese can pose a risk to human health, not all unpasteurized cheese is created equal. Some types of unpasteurized cheese may be safer than others, depending on factors like:
- The type of milk used: Cheese made from milk from grass-fed cows or goats may be safer than cheese made from milk from grain-fed cows.
- The cheese-making process: Cheese made using traditional methods, like raw milk cheese, may be safer than cheese made using modern methods.
- The aging process: Cheese that’s aged for a longer period may be safer than cheese that’s aged for a shorter period.
However, it’s essential to note that even if some types of unpasteurized cheese may be safer than others, there’s still a risk of foodborne illness associated with consuming these cheeses.
What Can You Do?
If you’re a cheese lover, don’t worry – you don’t have to give up cheese altogether. Here are some tips for enjoying cheese safely:

What is unpasteurized cheese and how is it different from pasteurized cheese?
Unpasteurized cheese, also known as raw milk cheese, is made from milk that has not been pasteurized, a process that involves heating the milk to a high temperature to kill off bacteria and other microorganisms. This type of cheese is often preferred by cheese enthusiasts for its rich, nuanced flavor and texture. However, the lack of pasteurization means that the milk used to make the cheese may contain pathogens like E. coli, Salmonella, and Listeria.
The main difference between unpasteurized and pasteurized cheese is the risk of contamination. Pasteurized cheese is made from milk that has been heated to a temperature that is hot enough to kill off most bacteria, making it a safer choice for consumption. Unpasteurized cheese, on the other hand, carries a higher risk of contamination, which can be particularly problematic for vulnerable populations like the elderly, pregnant women, and young children.
What are the risks associated with consuming unpasteurized cheese?
Consuming unpasteurized cheese can pose a number of health risks, particularly for vulnerable populations. The main risk is the potential for contamination with pathogens like E. coli, Salmonella, and Listeria. These bacteria can cause a range of symptoms, from mild stomach upset to life-threatening illnesses. In severe cases, contamination can lead to conditions like kidney failure, miscarriage, and even death.
The risks associated with unpasteurized cheese are particularly concerning for certain groups of people. Pregnant women, for example, are advised to avoid unpasteurized cheese altogether due to the risk of Listeria contamination, which can cause miscarriage and stillbirth. Similarly, the elderly and young children may be more susceptible to the effects of foodborne illness due to their weakened immune systems.
How common are foodborne illnesses associated with unpasteurized cheese?
Foodborne illnesses associated with unpasteurized cheese are relatively rare, but they can and do occur. According to the Centers for Disease Control and Prevention (CDC), there are approximately 48 million cases of foodborne illness in the United States each year, resulting in around 128,000 hospitalizations and 3,000 deaths. While not all of these cases are linked to unpasteurized cheese, the risk is still present and should be taken seriously.
