What You'll Learn

Brie cheese in the US is usually pasteurized
In the United States, it is very rare to find unpasteurized brie cheese. This is because, in 2004, the US government passed a law stating that any cheese aged under 60 days that is imported or sold in the country must be made with pasteurized milk. Brie is a "young" cheese, typically aged for 40-45 days, and the traditional French version is usually unpasteurized and aged for under five weeks. As a result, it is difficult to import authentic French brie into the US, and it is never sold commercially unless it is smuggled.
Brie is a soft, mould-ripened cheese that originated in the region of Brie in France, now called Seine-et-Marne. It is traditionally made with raw cow's milk, exposed to natural moulds in caves, cellars, and other cool, dark storage places. The moulds cause surface yeast to bloom into a rind and flavour the creamy interior as the cheese matures. This traditional production method results in a creamy, oozing texture and a complex flavour profile that is highly regarded by cheese purists.
However, unpasteurized brie carries a high risk of foodborne illness, especially for pregnant women, the elderly, and individuals with weakened immune systems. The pasteurization process, discovered by Frenchman Louis Pasteur, heats milk to a specific temperature, killing harmful bacteria and making dairy products safer to consume. While it can alter the flavour and texture of the cheese, pasteurization is an important safety measure, especially for those with higher health risks.
In the US, commercially produced brie cheeses are typically pasteurized as a standard safety measure. This means that while the brie available in American markets may not be the "real" or "authentic" French version, it is safer to consume, particularly for individuals with higher health risks. It is important to note that even pasteurized brie can carry a risk of foodborne illness if it is not produced, stored, or handled safely. Therefore, it is recommended to bake pasteurized brie to an internal temperature of at least 165°F (74°C) to reduce the risk of illness.

Unpasteurized brie is linked to a higher risk of foodborne illness
In the United States, imported cheeses must be pasteurized and aged for at least 60 days, so it is rare to find unpasteurized brie in American markets. Most commercially produced brie cheeses in the United States and many other countries are also pasteurized as a standard safety measure.
However, some specialty or artisanal brie cheeses may be made from unpasteurized milk. Unpasteurized brie carries a higher risk of foodborne illness because it has not undergone the heat treatment process that eliminates harmful bacteria, viruses, and parasites. Pasteurization involves exposing the substance to a specific temperature for a predetermined duration, effectively destroying pathogens without significantly altering the product's nutritional value or flavour.
Unpasteurized brie poses a particularly high risk for pregnant women, the elderly, and individuals with weakened immune systems. This is because unpasteurized cheese can contain harmful bacteria that can cross the placenta and infect the fetus, and people with weakened immune systems are more susceptible to infections.
Even pasteurized brie carries some risk of foodborne illness, especially if it is produced in facilities with unsanitary conditions or not stored or handled safely. However, baking pasteurized brie to an internal temperature of at least 165 degrees Fahrenheit (74 degrees Celsius) can significantly reduce the risk of illness.

Pregnant women should avoid unpasteurized brie
It is generally advised that pregnant women avoid consuming unpasteurized brie due to the risk of Listeria contamination. Brie is a soft cheese made from cow's milk that has been exposed to natural molds, resulting in its characteristic creamy texture and flavor. While pasteurization effectively eliminates harmful bacteria, viruses, and parasites, unpasteurized brie may contain Listeria, which can cause listeriosis, a severe infection that poses a significant risk to pregnant women and their babies.
Listeriosis can lead to flu-like symptoms in healthy individuals, but for pregnant women, it can have more serious consequences, including miscarriage or stillbirth. The risk of Listeria infection is ten times higher for pregnant women, and the suppression of the immune system during pregnancy further increases their susceptibility. Therefore, it is crucial for pregnant women to exercise caution when consuming soft cheeses like brie.
To ensure food safety, it is recommended to opt for pasteurized brie, which has undergone heat treatment to eliminate harmful pathogens. Most commercially available brie cheeses in the United States and other countries are pasteurized as a standard safety measure. However, it is important to read labels carefully, as unpasteurized brie may pose potential health risks, especially for pregnant women.
While pasteurization significantly reduces the risk of foodborne illnesses, it may not kill all bacteria in the cheese. Some experts advise against consuming any soft cheese during pregnancy due to the risk of Listeria contamination, even in pasteurized products. Cooking or baking pasteurized brie to an internal temperature of at least 165°F (74°C) can further reduce the risk of illness, making it safer for consumption by pregnant women.

Unpasteurized brie is hard to find in the US
In 2004, the United States government passed a law stating that any cheese aged under 60 days imported to or sold in the country must be made with pasteurized milk. This law was implemented to enhance food safety and reduce the risk of harmful bacteria, such as E. coli, salmonella, and listeria, which can cause severe health issues. As Brie is a "young" cheese, typically aged for only 40-45 days, it rarely makes it into the US borders and is never sold in American cheese markets.
The FDA has strict criteria for imported cheese, which means that some French cheeses, including Brie, Camembert, Reblochon, and Roquefort, are made with raw milk products that are illegal in the USA. This difference in regulations between the US and France, where Brie originates, makes it nearly impossible to find authentic, unpasteurized Brie in the US. The Brie sold in the US is typically an impostor, a pasteurized version of the traditional French cheese.
While the pasteurization process kills harmful bacteria and extends the shelf life of cheese, it also alters the flavour and texture of Brie. The raw milk used in traditional Brie contributes to a much more intense flavour, often retaining notes of the types of food on which cows graze. The French place a high value on maintaining the traditional Brie flavour, and some consumers prefer the raw, unpasteurized variety for its complexity and texture. However, due to the health risks associated with unpasteurized Brie, it is challenging to find this version in the US outside of the black market.

Pasteurization does not significantly alter nutritional value
While some people believe that raw milk is healthier than pasteurized milk, the latter is safer for human consumption. Pasteurization is a heat treatment that eliminates harmful bacteria, viruses, and parasites from food and beverages. It involves exposing the substance to a specific temperature for a predetermined duration, effectively destroying pathogens.
In the United States, imported cheeses must be pasteurized and aged for at least 60 days. This is why pasteurized forms of Brie dominate American markets. However, traditional Brie, made with raw cow's milk, is still available in France and other European countries.
Unpasteurized Brie carries a high risk of foodborne illness, especially for pregnant women, the elderly, and individuals with weakened immune systems. It is also less widely available than pasteurized varieties due to safety concerns. To reduce the risk of foodborne illness, it is recommended to bake pasteurized Brie to an internal temperature of at least 165°F (74°C).
Although pasteurization can affect the nutritional value of Brie, the impact is not significant. It preserves the majority of the cheese's nutritional content, including essential vitamins, minerals, and proteins. While it does decrease the concentration of some vitamins, such as B2, pasteurized Brie is still an important dietary source of these nutrients. Additionally, vitamin D fortification is mandatory for pasteurized milk sold in Canada, making it an excellent source of this vitamin, which is lacking in raw milk. Overall, the benefits of pasteurization in terms of food safety and extended shelf life outweigh any minor losses in nutritional value.
