Cheddar cheese, a beloved staple in kitchens worldwide, comes in various forms, from mild to sharp, aged to fresh. But one particular variety sparks considerable debate: raw cheddar cheese. Is it safe to consume? The answer is complex, involving a careful consideration of potential risks, purported benefits, and the regulatory landscape that governs its production and sale.
Understanding Raw Cheddar Cheese
Raw cheddar cheese, unlike its pasteurized counterpart, is made from milk that has not been heated to a specific temperature to kill harmful bacteria. This fundamental difference is what sets it apart and fuels the controversy surrounding its safety.
The Cheesemaking Process: Raw vs. Pasteurized
The typical cheesemaking process, regardless of whether it uses raw or pasteurized milk, involves several key steps. First, milk is collected and, in the case of pasteurized cheese, heated to eliminate potentially harmful microorganisms. Then, starter cultures are added to acidify the milk, followed by rennet to coagulate it into curds. These curds are cut, cooked, and drained of whey. Finally, the curds are pressed into molds and aged, a process that can last from weeks to years, depending on the desired flavor and texture.
The crucial distinction lies in the pasteurization step. Proponents of raw milk cheese argue that this process, while eliminating harmful bacteria, also destroys beneficial enzymes and microorganisms that contribute to the cheese’s unique flavor profile and potential health benefits. Pasteurization is designed to make milk safer but some feel it sacrifices flavor and possible health advantages.
What Does “Raw” Really Mean?
When we talk about “raw” cheddar, we’re specifically referring to cheese made from milk that hasn’t undergone pasteurization. There is no heating process involved that meets pasteurization temperature standards. This is crucial to understanding the risks and benefits involved. It’s important to know the origin of the milk and the processes used to create the raw cheddar you intend to consume.
Potential Risks of Consuming Raw Cheddar
The primary concern surrounding raw cheddar cheese is the presence of potentially harmful bacteria that can thrive in unpasteurized milk. These bacteria can cause foodborne illnesses, ranging from mild discomfort to severe health complications.
Common Bacterial Contaminants
Several types of bacteria are commonly associated with raw milk and raw milk products, including:
-
E. coli: Some strains of E. coli, particularly E. coli O157:H7, can cause severe diarrhea, abdominal cramps, and vomiting. In severe cases, it can lead to kidney failure.
-
Salmonella: Salmonella infection can cause diarrhea, fever, and abdominal cramps.
-
Listeria: Listeria monocytogenes can cause listeriosis, a serious infection that can be particularly dangerous for pregnant women, newborns, older adults, and people with weakened immune systems.
-
Campylobacter: Campylobacter infection can cause diarrhea, abdominal pain, and fever.
These bacteria, if present in the raw milk used to make cheddar cheese, can survive the cheesemaking process and pose a risk to consumers.
Who is Most Vulnerable?
Certain populations are more susceptible to the harmful effects of bacteria found in raw cheddar cheese. These include:
-
Pregnant women: Listeriosis can cause miscarriage, stillbirth, premature delivery, or serious illness in newborns.
-
Infants and young children: Their immune systems are not fully developed, making them more vulnerable to severe infections.
-
Older adults: Their immune systems may be weakened, increasing their risk of complications.
-
Individuals with weakened immune systems: People with conditions like HIV/AIDS, cancer, or those taking immunosuppressant medications are at higher risk.
For these groups, avoiding raw cheddar cheese is generally recommended.
The Importance of Proper Handling and Storage
Even if raw milk is initially free from harmful bacteria, contamination can occur during the cheesemaking process or subsequent handling. Proper hygiene practices, such as washing hands and sanitizing equipment, are crucial in preventing contamination. Furthermore, proper storage at appropriate temperatures is essential to inhibit bacterial growth.
Potential Benefits of Raw Cheddar
While the risks associated with raw cheddar cheese are undeniable, proponents argue that it also offers potential health benefits that are lost during pasteurization.
Nutritional Advantages
Raw milk is believed to retain more of its natural nutrients and enzymes compared to pasteurized milk. This is a central argument made by enthusiasts. Some of the key nutritional differences may include:
-
Enzymes: Raw milk contains enzymes that aid in digestion and nutrient absorption. Pasteurization can destroy these enzymes.
-
Vitamins: Some vitamins, such as vitamin B12 and vitamin C, may be present in higher concentrations in raw milk.

Probiotics: Raw milk naturally contains beneficial bacteria that can contribute to gut health.
However, it’s important to note that the nutritional differences between raw and pasteurized milk can vary depending on factors such as the cow’s diet and the processing methods used.
Flavor and Texture
Many cheese connoisseurs appreciate raw cheddar for its complex and nuanced flavor profile. The absence of pasteurization allows for a wider range of microorganisms to contribute to the cheese’s development, resulting in a more intense and varied taste.
The texture of raw cheddar can also differ from that of pasteurized cheddar. Raw milk cheeses often have a firmer, more crumbly texture due to the different protein structure.
Potential Allergy Benefits
Some studies suggest that exposure to raw milk early in life may reduce the risk of developing allergies and asthma. However, more research is needed to confirm these findings, and the potential risks of consuming raw milk must be carefully weighed against any potential benefits.
Regulations and Legality
The sale and consumption of raw milk and raw milk products are subject to strict regulations in many countries, including the United States.
Regulations in the United States
In the United States, federal law prohibits the interstate sale of raw milk for human consumption. However, individual states have the authority to regulate the intrastate sale of raw milk. Some states allow the sale of raw milk in retail stores, while others only permit it on farms or through herd-sharing agreements. Some states completely ban the sale of raw milk.
The Food and Drug Administration (FDA) is responsible for enforcing federal regulations regarding raw milk. The FDA has consistently warned against the consumption of raw milk due to the risk of foodborne illness.
Regulations in Other Countries
The regulations surrounding raw milk and raw milk products vary widely around the world. Some countries, like Switzerland, have a long tradition of consuming raw milk products and have relatively lenient regulations. Other countries, like Canada, have stricter regulations.

What exactly is raw cheddar cheese, and how does it differ from regular cheddar?
Raw cheddar cheese is made from unpasteurized milk, meaning the milk hasn’t been heated to kill potentially harmful bacteria. This differentiates it significantly from regular cheddar, which is produced using pasteurized milk that undergoes a heating process to eliminate many bacteria. The absence of pasteurization in raw cheddar allows naturally occurring enzymes and bacteria in the milk to remain active, influencing its flavor and texture development.
This difference in processing leads to a cheddar with a more complex and nuanced flavor profile, often described as having more earthy, tangy, and robust notes compared to the milder and more consistent taste of regular cheddar. Texturally, raw cheddar may exhibit a crumbly and less uniform structure due to the active enzymes breaking down the milk proteins during the aging process. Regular cheddar tends to be smoother and more pliable.
What are the potential health risks associated with consuming raw cheddar cheese?
The primary risk associated with raw cheddar consumption stems from the potential presence of harmful bacteria such as E. coli, Salmonella, Listeria, and Campylobacter. These bacteria can survive in unpasteurized milk and, if present in sufficient quantities, can cause foodborne illnesses, leading to symptoms like nausea, vomiting, diarrhea, abdominal cramps, and fever. Individuals with weakened immune systems, pregnant women, young children, and older adults are particularly vulnerable to severe complications from these infections.
While cheesemaking processes, including acidification, salting, and aging, can help control bacterial growth, they don’t eliminate the risk entirely. Regulations exist to minimize these risks, but occasional outbreaks linked to raw milk cheeses do occur. It is crucial to consider these risks carefully before consuming raw cheddar, especially for those in high-risk groups.
What are the purported health benefits of raw cheddar cheese that some people believe in?
Proponents of raw cheddar cheese often cite its potential for containing beneficial bacteria and enzymes that are destroyed during pasteurization. They believe these live microorganisms contribute to improved gut health by supporting a more diverse and balanced microbiome. The enzymes are thought to aid in the digestion of lactose and other milk components, potentially making raw cheddar easier to tolerate for individuals with mild lactose sensitivity.
Furthermore, raw milk enthusiasts suggest that raw cheddar retains higher levels of certain vitamins and minerals, such as vitamins A, D, and K2, as well as calcium, compared to pasteurized cheddar. They argue that the natural state of the milk allows for better nutrient absorption and utilization by the body. However, it’s important to note that scientific evidence supporting these claims is often limited, and the potential benefits must be weighed against the documented risks.
How are raw cheddar cheese products regulated to ensure safety?
Raw cheddar cheese production is typically subject to regulations designed to minimize the risk of contamination and bacterial growth. These regulations often include stringent standards for milk quality, hygiene during cheesemaking, and temperature control throughout the production and aging process. Many jurisdictions require regular testing of raw milk and finished products to detect the presence of harmful pathogens.
Furthermore, aging requirements are frequently mandated, with minimum aging periods (often 60 days in the U.S.) believed to reduce the risk of harmful bacteria. The longer aging period allows natural enzymes to break down proteins and sugars, making the environment less hospitable for some pathogens. These regulations vary by region, so understanding the specific rules in your area is crucial when assessing the safety of raw cheddar.
What should I look for when purchasing raw cheddar cheese to minimize my risk of getting sick?
When considering purchasing raw cheddar, prioritize reputable producers who adhere to stringent hygiene and safety practices.
