Consuming raw cheese made from unpasteurized milk carries certain health risks. These include exposure to harmful pathogens, increased danger for vulnerable populations, and a history of public health outbreaks linked to raw milk cheese.
Potential Pathogens
Raw cheese can harbor harmful bacteria such as Listeria, E. coli, Salmonella, and Campylobacter. These pathogens can cause severe illnesses and infections. The lack of pasteurization means bacteria present in the raw milk might survive and multiply during the cheese-making process.
Bacteria contamination can result from improper handling or unsanitary conditions. The Food and Drug Administration (FDA) emphasizes the risks connected with consuming bacteria-laden raw cheese. Even a small amount can lead to serious food poisoning, especially since pathogens like Listeria can thrive in cooler temperatures typically used for cheese aging.
Vulnerable Populations
Certain groups are more susceptible to infections from raw cheese. Pregnant women, children, the elderly, and individuals with a compromised immune system due to conditions like chronic diseases are at higher risk. For these populations, the bacteria in raw cheese can lead to more severe health outcomes.
For instance, Listeria infection during pregnancy can result in miscarriage, stillbirth, or severe illness in newborns. In older adults and those with lower immune responses, infections can lead to long-term complications. The Centers for Disease Control and Prevention (CDC) recommends that these vulnerable groups avoid raw milk products to minimize the risk of severe illness.
Outbreaks and Public Health
There have been several notable public health outbreaks linked to raw cheese consumption. Listeria and E. coli outbreaks have caused recalls and heightened scrutiny from health agencies. These outbreaks highlight the potential for widespread health impacts from a single contaminated cheese batch.
Statistics from the CDC indicate that raw milk products are responsible for a disproportionate number of foodborne illnesses.

Public health measures aim to protect consumers by ensuring that vulnerable groups remain informed about the dangers of raw cheese.
Legal and Regulatory Framework
Regulations surrounding raw milk cheese differ significantly between the US and other countries. These guidelines aim to control safety standards and manage risks associated with consuming unpasteurized dairy products.
US Regulations
In the United States, raw milk cheese must comply with strict guidelines enforced by federal agencies. The U.S. Food and Drug Administration (FDA) enforces a 60-day aging rule, requiring raw milk cheese to be aged for at least 60 days to reduce harmful bacteria levels. This rule is intended to allow the natural acidity and aging processes to kill pathogens.
Additionally, there are restrictions against selling raw milk cheese across state lines due to varying state regulations. Testing for non-toxigenic E. coli is another safety measure, serving as an indicator of fecal contamination. The Farm-to-Consumer Legal Defense Fund often advocates for more flexible regulations to support small-scale raw milk producers.
International Guidelines
International regulations, such as those in France, tend to be more lenient while still prioritizing public safety. France is known for its tradition of raw milk cheese production, and local laws focus on comprehensive microbial testing rather than imposing aging rules. Incorporating scientific assessments and adjusting protocols based on new findings are common practices.
Different countries have varied approaches to these regulations. European guidelines typically include extensive microbial testing and risk categorization to ensure safety. These regulations are continually updated and influenced by organizations like the European Commission.
While the US adopts more prescriptive rules, European and other international approaches rely on rigorous ongoing testing and monitoring to manage risks.
Production and Aging Processes
The production and aging of raw cheese involve specific techniques and conditions that contribute to its quality, safety, and unique characteristics.
Cheese Making Techniques
Raw cheese is created using milk that has not been pasteurized. This milk retains natural enzymes and bacteria that can influence the flavor and texture of the cheese.
The initial stages of cheese making involve carefully selecting quality milk from dairy animals like cows, goats, or sheep. This milk is then coagulated using rennet or other acids, separating the curds from the whey.
After the curd formation, the curds are cut, drained, and sometimes cooked to achieve the desired texture. They are then molded into shapes and salted to enhance flavor and preservation. The techniques can vary significantly, affecting the final product’s moisture content, texture, and taste.
Aging and Its Effects on Cheese
The aging process, also known as affinage, is critical for developing the flavors and textures of cheese. Aging times can range from a few weeks to several years. Soft cheeses may be aged briefly, while hard cheeses typically undergo longer periods of maturation.
Temperature and humidity control are essential throughout aging. Ideal conditions allow beneficial molds and bacteria to flourish, contributing to the terroir — the unique taste and character imparted by the cheese’s environment.
Enzymatic activity during aging breaks down proteins and fats, altering the texture from creamy to crumbly, depending on the cheese type. As cheese ages, its shelf life can increase, but it may require refrigeration to maintain quality.
By understanding these processes, consumers can better appreciate the complexity and craftsmanship of raw cheeses.
