Cheddar Cheese: Unpasteurized Or Not?

is cheddar cheese unpasteurized

Cheddar cheese is generally safe to consume during pregnancy, provided it is made from pasteurized milk. Pasteurization is a process that involves heating milk to eliminate harmful bacteria and reduce the risk of foodborne illnesses. While most commercially available cheddar cheese is pasteurized, it is advisable to check the product label for confirmation. Notably, unpasteurized cheddar cheese, such as Keens' cheddar, is also available and tends to have a strong, nutty, and creamy flavor.

Pasteurized cheese is safer for pregnant women to eat

Pregnancy is a time when women are advised to be extra cautious about their diet. While cheese is a great source of nutrition, offering protein and many vitamins, it is important to know which types are safe to eat.

Cheddar cheese, for example, can be found in both pasteurized and unpasteurized forms. Pasteurization is a process that heats food to a certain temperature, killing off harmful bacteria. This process makes cheese safer to eat, as it reduces the likelihood of contamination or bacteria. Therefore, pasteurized cheddar cheese is safer for pregnant women to eat than unpasteurized cheddar cheese.

Unpasteurized cheese, also known as raw cheese, may contain harmful bacteria such as Listeria, which can cause listeriosis. Listeriosis is a serious concern for pregnant women, as it can lead to infection or illness. In fact, pregnant people make up about one out of every six people who develop listeriosis, and they are 18 times more likely to get the infection than non-pregnant adults.

To ensure food safety, it is recommended that pregnant women choose pasteurized cheese over unpasteurized varieties. Pasteurized cheeses are widely available in stores and are considered safe for consumption during pregnancy. However, it is still important to read labels carefully and look for the word "pasteurized" when selecting cheeses. Additionally, when buying soft cheeses, it is safer to purchase individual rounds of pasteurized cheese rather than pieces cut from a larger wheel to avoid cross-contamination.

While cheddar cheese can be enjoyed by pregnant women, it is always advisable to consult a healthcare professional for specific dietary guidelines during pregnancy.

Unpasteurized cheese is considered unsafe in many countries

The consumption of unpasteurized, or raw, milk cheese may be risky, and the CDC and Food and Drug Administration (FDA) recommend that people do not consume raw milk or raw milk products. The standard medical advice is to avoid all unpasteurized cheese, especially for children, adults over 65, pregnant people, and immunocompromised people. The American College of Obstetricians and Gynecologists agrees with the recommendations of the FDA and directs patients to avoid certain foods that might bear a higher risk of Listeria.

In the United States, the FDA requires raw-milk cheese, both domestic and imported, to be aged for at least 60 days before it can be sold. This aging process is intended to kill harmful microbes such as Salmonella, Listeria, and E. coli, which can survive the cheese production and aging process. However, it is not known whether this aging process would kill or inactivate the avian flu virus, which has been found in dairy cows.

Despite the potential risks, some people choose to consume unpasteurized cheese for its richer, more complex flavor and texture. In some countries, such as Australia and New Zealand, the import or sale of nearly all unpasteurized cheeses is prohibited, regardless of age. In contrast, other countries, like those in the European Union, have different regulations and allow the sale of unpasteurized cheese. For example, traditional cheddars like Keens' cheddar cheese, made with unpasteurized milk, are available in the United Kingdom.

Unpasteurized cheddar has a strong, nutty, and creamy taste

Unpasteurized cheddar is a traditional English cheese with a strong, nutty, and creamy flavour. It is made with unpasteurized milk, which gives it a unique taste. The process of pasteurization involves heating milk to a high temperature to kill off bacteria and other microorganisms, but this can also affect the flavour of the cheese. Unpasteurized cheese retains more of the flavour of the milk, which can reflect what the animals were grazing on, leading to a more intense and complex flavour profile.

Keens' cheddar cheese, for example, is a well-known variety of unpasteurized cheddar that has been handmade by the same family business since 1899. It has a strong, nutty, and creamy taste that makes it perfect for melting, adding to a cheeseboard, or including in a sandwich. The flavour of unpasteurized cheddar is often described as "real" and "strong", with a depth of flavour that is lacking in pasteurized cheddar.

However, it is important to note that unpasteurized cheese carries a risk of contamination with bacteria and other pathogens, which can cause foodborne illnesses. These risks are particularly relevant for pregnant women, young children, older adults, and people with weakened immune systems. Hard cheeses like cheddar, which have a lower moisture content, tend to be less hospitable to bacterial growth, and aging the cheese can also help to kill off bacteria.

Despite the risks, many people enjoy the complex flavour profiles and lingering taste of unpasteurized cheese. The decision to consume unpasteurized cheese ultimately comes down to personal preference, with some opting for the flavour of unpasteurized cheese while others prioritize the safety of pasteurized options.

Pasteurization involves heating milk to kill harmful bacteria

Pasteurization is a process that involves heating milk to a certain temperature to kill harmful bacteria. This process is often used in the production of dairy products such as cheese to reduce the risk of foodborne illnesses.

During pasteurization, milk is typically heated to a temperature of around 72°C (161°F) for about 15 seconds. This temperature is hot enough to destroy bacteria such as Listeria, which can cause serious illnesses. The process also helps to extend the shelf life of the milk and improve its overall safety.

When it comes to cheddar cheese, pasteurization plays a crucial role in ensuring its safety, especially for pregnant women. Cheddar cheese is generally safe to consume during pregnancy, but it is recommended to choose cheddar made from pasteurized milk to reduce the risk of foodborne illnesses. Most commercially available cheddar cheeses are pasteurized, but it is always a good idea to check the product label to confirm.

Some people may prefer the taste of unpasteurized cheddar cheese, also known as raw milk cheese. Unpasteurized cheddar, such as Keens' cheddar cheese, is produced using unpasteurized milk to maximize flavor. It has a strong, nutty, and creamy taste that makes it perfect for melting, cooking, or eating on its own. However, it's important to note that unpasteurized cheese may pose higher health risks, especially for pregnant women, as it has a higher chance of harboring harmful bacteria.

In some countries, such as Australia and New Zealand, the import and sale of unpasteurized cheese are prohibited due to safety concerns. It is always recommended to follow local health guidelines and consult a healthcare professional for personalized advice regarding cheese consumption, especially during pregnancy.

Hard, dry, salty, and acidic cheeses are less likely to grow pathogens like Listeria

Listeria, or Listeriosis, is a disease caused by the bacteria Listeria monocytogenes. It is a relatively rare disease, with 0.1 to 10 cases per 1 million people per year, but it has a high rate of death, making it a significant public health concern. L. monocytogenes can be found in many places, including soil, water, vegetation, and animals. It can survive and grow even under refrigeration, and it can cross-contaminate other foods that have been cut and served on the same cutting board or stored in the same area.

Certain cheeses are more likely to make people sick from Listeria than others. This is because some cheeses are made in a way that allows Listeria to contaminate the cheese and grow. High-moisture, creamy, soft, and fresh cheeses that do not go through a significant aging process are more likely to harbor or grow pathogens like Listeria. Cheeses made with unpasteurized (raw) milk are also more likely to contain Listeria and other germs that make people sick.

However, hard, dry, salty, and acidic cheeses are less likely to grow pathogens like Listeria. These cheeses can be unpasteurized but aged for well over 60 days. Examples of such cheeses include Aged Gouda (Beemster, Parrano, Prima Donna, or Reypenaer), cheddar (Cabot Clothbound, Dubliner, Excalibur, or Old Croc), Manchego, Parmesan (not Parmigiano-Reggiano), or Piave. It is worth noting that even these cheeses are not immune to the risks of cross-contamination, and whole intact cheeses are less likely to be contaminated. For those who want to be extra cautious, there are also many aged pasteurized cheeses available.

While good practices on farms can reduce contamination, they cannot guarantee safety from harmful germs. Pasteurized milk offers the same nutritional benefits without the risks of raw milk consumption. The CDC and the FDA recommend that everyone choose pasteurized milk and dairy products. However, it is important to note that some people enjoy the strong, nutty, and creamy flavor that unpasteurized cheeses offer. For example, Keens' cheddar cheese, a traditional cheddar cheese made with unpasteurized milk, has a strong flavor that is perfect for cooking and eating on its own.
